ADDITIONAL INFORMATION
•J2EE (Java 2 Enterprise Edition) includes Java Specification enhancements that allow client-server applications to
work with different clients. The J2EE application server provides execution environments and services, which can be
used by clients (Web Container, EJB Container, and interfaces to resources such as JDBC, JMS, and JCA).
Defined and enhanced by Sun (not Open Source), Java is a programming language developed for using applets in
Web applications. The paradigm is “write once, run everywhere.” The compiler creates machine-independent byte
code (class file) execution required by JVM as runtime environment.
•Java Servlets define an API and framework for basic request and response processing.
•Java Server Pages define a standard for building dynamic Web pages using Java code and custom tag libraries.
•Enterprise JavaBeans describe a distributed-component model with built-in services, such as transaction
management, object pooling, and automated persistence.
•Web Container implements the Web component contract of the J2EE architecture.
•EJB Container is a software that runs on a server and manages the EJBs.
•JNDI (Java Naming and Directory Interface) provides a unified interface to multiple naming and directory services.
•JAAS (Java Authentication and Authorization Service) provides a set of APIs that enables services to authenticate
and enforce access controls on users.
JDBC (Java Database Connectivity) provides a generic API for access to relational databases.
•JMS (Java Message Service) provides generic API for accessing point-to-point and publish and subscribe queues.
•JCA (J2EE Connector Architecture) provides an abstraction layer between application components and Enterprise
Information Systems (EIS).
•JVM (Java Virtual Machine) is the runtime environment for byte code. Sun delivers JVM implementations for many
platforms, while other vendors (such as J2EE) implement custom JVMs (such as JRockit and IBM JVM).
•JRE (Java Runtime Environment) is JVM plus supporting class files.
•JDK/Java SDK (Java Development Kit) is the development environment, with a compiler, packager, and other tools.
•JTS/JTA (Java Transaction Service/Java Transaction API) API offers global transactions spanning multiple
resources.

Content Engine Authentication
„
The IBM FileNet P8 authentication process uses two
standards:
1. Java Authentication and Authorization Service (JAAS)
– The framework for security interoperability in a J2EE
environment
2. Web Services Security standard (WS-Security)
– The framework in the heterogeneous environment of
clients and servers that communicate through Web
services interfaces
„
Note: This course uses JAAS.
16
HELP PATH
FileNet P8 Documentation > FileNet P8 Administration > Enterprise-wide Administration > FileNet P8 Security >
> Authentication
ADDITIONAL INFORMATION
The Content Engine Enterprise JavaBeans (EJB) resides within the J2EE Application Server EJB container.
The CE EJB is therefore accessible only by authenticated callers, those who can pass any authorization checks
that the administrator has placed on the EJB.

17
HELP PATH
FileNet P8 Documentation > FileNet P8 Administration > Enterprise-wide Administration > FileNet P8 Security >
> Authentication
ADDITIONAL INFORMATION:
JAAS configurations
To use a J2EE-based application, a client must first perform a JAAS log-in by specifying a JAAS configuration
(in a file).
The JAAS configuration specifies the authentication technologies (LoginModules) that will be used to verify the
client's credentials.
A JAAS configuration file lists one entry for each configured application. Within an application entry is a list of
LoginModules for that application. Based on the contents of the configuration file, the JAAS framework
dynamically determines which set of authentication technologies to invoke when a client application attempts to
authenticate.
JAAS LoginContexts
A J2EE client application must specify a JAAS configuration and a mechanism through which credentials can be
obtained from a user at run time. These two items constitute a JAAS LoginContext. J2EE client applications use
the LoginContext to interact with JAAS and to authenticate themselves to a J2EE server.
JAAS LoginModules
JAAS-compliant LoginModules are implemented by authentication technology providers. J2EE application
server vendors, such as BEA, IBM, and JBOSS, typically provide LoginModules for standard types of
credentials, such as username and password
JAAS Subjects
When a JAAS log-in has successfully completed, a JAAS Subject is returned to the caller. The Subject is a key
J2EE class, which is transparently sent between J2EE clients and J2EE servers any time an EJB is invoked.
A JAAS Subject contains the set of JAAS principals (authenticated identities) and JAAS credentials
(authentication data such as cryptographic keys) that result from the log-in process. Each LoginModule that
successfully authenticates the user updates the Subject with information about the user. A J2EE server
application can examine the principals in the Subject to establish the caller's identity.

to the CE Server
„
The FileNet P8 CE installation provides JAAS
configuration sample files
y Examples:
– jaas.weblogic.config
– jaas.websphere.config
„
Legacy support
y CE API does an internal JAAS log-in
y The client environment must include a proper JAAS
configuration
y The username and password model using the UserContext
class is not supported
18
HELP PATH
FileNet P8 Documentation > FileNet P8 Administration > Enterprise-wide Administration > FileNet P8 Security >
> Authentication
ADDITIONAL INFORMATION
The client application obtains a JAAS Subject prior to calling the Content Engine Java API. Interactions with the
CE Java API cause the Content Engine EJB to be invoked. The client's JAAS subject is transparently sent to the
J2EE application server with each EJB call. The application server validates the JAAS subject and confirms the
caller's identity before executing any code in the Content Engine EJB.

Factory.Connection.getConnection(…)
2. Authenticate with the application server
UserContext.createSubject(…)
3. Get the UserContext object associated with the current thread
UserContext.get()
4. Make the specified JAAS Subject active

Factory.Connection.getConnection(…)
public static Connection getConnection(String uri)
„
Parameters
y uri - Specify the Universal Resource Identity (URI) for this connection
WebLogic - t3://servername:port/FileNet/Engine
WebSphere - iiop://servername:port/FileNet/Engine
„
Returns
y A Connection object
„
Notes:
y A domain connection is required to obtain a reference to any object
y
stored within that domain.
This method uses default configuration parameters.
11
ADDITIONAL INFORMATION
•There is another variation of this method (takes additional parameter for configuration):
public static Connection getConnection(java.lang.String uri,
ConfigurationParameters parameters)
•Configuration parameters represent a group of parameters that defines the behavior of the client API.
•The method discussed in the slide is equivalent to calling getConnection(uri, new ConfigurationParameters()).

– The following characters are not allowed: * \ / : * ? " % & > |
„
Returns

12
ADDITIONAL INFORMATION
Three methods are used to create a subfolder:
Factory.Folder.createInstance(…)
ObjectStore.createObject(…)
Folder.createSubFolder(…)
There is no performance difference among these methods. However, the createSubFolder() method is
preferred for type-safety reasons. It ensures that a couple of required properties are set on the newly created
subfolder. Factory.Folder.createInstance() method is also discussed on the next slide and used in the code.

What Are Custom Objects?
„
A custom object is an object without content
y Created to model its business process usage
y Named for its business process usage
y Used to store properties
„
Like a Document object, a custom object

Is independently securable
Can be persisted in an object store
Can be filed into a folder
Can have annotations associated with it
Can subscribe to server-side events

Create Custom Objects
Why Use Custom Objects?
„
Use custom objects when
y The object simply stores properties
y Saved versions of the object are not needed
y Custom properties are needed for the objects in a class
„
Applications often associate custom properties with
the objects they process
y Create a CustomObject subclass for each set of
application-specific custom properties
y To link the subclass with another object, create a custom
property that points to the associated object by using the
associated object GUID as the value

y Is an instance of the document class or a subclass
„
A Document object can have the following:
y One or more content elements
y Associated annotations
y Metadata or properties that are used for identification
„
Document content elements are stored

„
Notes
y This method creates a new instance of ContentReference class.
y This object is a dependent object.
y It is persisted on the server when its parent object has been saved.
20
ADDITIONAL INFORMATION
• The ContentReference object represents external content data that exists outside of an object store (and therefore
outside the control of the Content Engine server), but to which an object store maintains a reference.
• The URL of the resource that contains the content data is stored in the ContentLocation property.
• The object is persisted to an object store when its parent object (the independently persistable object that
references it) is persisted.
• The most frequently used form of this method takes no arguments. Since a dependent object is persisted to the
object store of its parent, there is no need to specify an object store.
• A second form of this method, provided for backward compatibility with the FileNet P8 Content Engine COM API,
takes an object store argument. If the specified object store is not that of the parent object, an exception is thrown
when the parent is persisted.

The autoClassify parameter specifies whether the document should have automatic document classification
enabled. This autoClassify and versions are discussed in separate lessons and modules.
Before you can determine if a document has content, you must set the content for the document.
If you do not want the Content Engine to assign a MIME type to the checked-in document, you must explicitly set
the value.

Instructor Notes:
Inconsistency in retrieving a document using the folder path and document name:
I have run “add document code” more than once with the document name hard coded. It ended up adding two documents
with the same name on the same folder (it did not complain). When I tried to retrieve the document with the path, it threw
an error.
Even after deleting the duplicate document, it still did not work. However, I was able to retrieve it using the GUID. The
documents that are added once did not have this problem. They were retrieved using folder path.

Scalar data types are Binary, Boolean, DateTime, Float, ID, Integer, String. There is a single Object-valued type,
and it is used to represent an object. For example, the annotations associated with a document can be
represented as Object type properties for the document..

HELP PATH
FileNet P8 documentation > Developer Help > Content Engine Development > Java and .NET developer’s Guide >
Properties > Concepts >Property Cache Concepts
ADDITIONAL INFORMATION
To save system resources, each Content Engine object maintains a local (client-side) property cache from which one
or more of an object's properties, if available, can be retrieved.
Object refresh method pulls properties from the server. It replaces the object’s properties currently in cache and adds
any new properties not in cache.
Fetch property or fetch properties methods merge with existing properties and add any new properties not in cache.
Object setter methods are used in your program to write values to properties. You learned about Properties.putValue
in an earlier module. There is also the Property.setObjectValue(java.lang.Object val) method.
Get property or getProperties methods retrieve from cache and throw an exception if a requested property is not in
cache.
The system has an internal property called the update sequence number that it uses to coordinate concurrent
updates among different applications

3.
When you create a new class (for example, a document class), the PropertyDescription that you choose is copied into
the class.
After the class is created, if you modify that PropertyDescription, it is not automatically updated in the Document class.
You need to delete the old PropertyDescription and add the new or modified one to the class.
After the updating the class, only newly created objects (for example, documents) will have the updated property.

SearchSQL
„
SearchSQL is a helper class
y Used to assist in building valid SQL statements.
y Used to pass an instance of this class in to the
SearchScope.fetchObjects method to perform a query.
13
ADDITIONAL INFORMATION
There are helper methods on the SearchSQL class to assist you in constructing an SQL statement. The next
lesson deals with these methods.
Alternatively, you can construct an SQL statement independently and pass it to a SearchSQL instance as a
string.
SQL statements need to follow the FileNet standard, which generally conform to SQL-92, with extensions for
FileNet-specific constructs. See SQL Syntax Reference for a complete description.

„
Parameters
y searchSQL – Specify a SearchSQL instance containing the
SQL statement to use for the search.
y pageSize – Specify an integer indicating the maximum number
of objects per page to retrieve. This can be null.
y filter - A PropertyFilter object that represents information for
controlling which property values (and with what level of
detail and recursion) to return.
„
Returns
y IndependentObject objects collection from the object stores
14
ADDITIONAL INFORMATION
When pageSize is unspecified, the default page size (ServerCacheCofiguration.QueryPageDefaultSize) is
used.
If the continuable parameter is false or null, the pageSize value is ignored.

searchScope.fetchRows(…)
public RepositoryRowSet fetchRows(
SearchSQL searchSQL,
Integer pageSize,
PropertyFilter filter
Boolean continuable)
Parameters
y continuable –
– If false or null, the query is not paged.
– If true, when the end of the first page is reached, a request
for the next page of Properties objects is issued.
– Page requests iterate until all of the Properties objects
satisfying the query are retrieved.
„
Returns
y RepositoryRowSet object Rows of properties from object
stores
15
ADDITIONAL INFORMATION
Parameters:
A PropertyFilter object - Represents information for controlling which property values (with what level of
detail and recursion) to return.
If null, this method returns values for all nonobject properties and returns placeholders for all object-valued
properties (PropertyEngineObject properties with a state of PropertyState.UNEVALUATED or
PropertyState.REFERENCE).
Any subsequent attempts to access an object-valued property cause an automatic roundtrip to the server to
fetch its value.
SearchSQL - The selection list in the searchSQL parameter determines which top-level properties are
returned.
The property filter specified here determines the subproperties: the properties returned for the applicable
top-level properties. For example, if a top-level property specified in the selection list (searchSQL parameter)
is of type Object, the filter parameter determines which properties are returned in that object.
Queries using continuation use ORDER BY in their implementation. If an ORDER BY clause is not specified
in the SQL statement (the searchSQL parameter), an ORDER BY Id clause is used. If an ORDER BY clause
is specified in the SQL statement but does not contain the Id property, the Id property (having a unique
value) is appended to the end of the ORDER BY clause. You need to consider whether the overhead of
adding the Id property to the ORDER BY clause is significant for your application. Do not use a continuable
query if it might cause a severe performance reduction.

„
Retrieves class description object from object stores.
„
Parameters
y classNames - Names of the classes to retrieve. Can be the
symbolic name, the display name, or the object ID for the
class.
y filter - Information for controlling which property values (and
with what level of detail and recursion) to return.
„

17
ADDITIONAL INFORMATION
If the SearchScope instance references multiple repositories, properties that are not applicable to multiple
repositories will not be present in the ClassDescription objects returned, and will not be present in the
PropertyDescription objects contained in these ClassDescription objects.
If the filter is null, this method returns values for all nonobject properties and returns placeholders for all
object-valued properties (PropertyEngineObject properties with a state of PropertyState.UNEVALUATED or
PropertyState.REFERENCE). Any subsequent attempts to access an object-valued property cause an
automatic roundtrip to the server to fetch its value.

Folder Operators
„
INFOLDER
y Matches object contained within specified folder.
y Folder ID
y Full path name
„
INSUBFOLDER
y Can be used only on subfolders that have the
Folder.Parent property set to the parent of the folder.
32
ADDITIONAL INFORMATION
The INFOLDER operator matches an object contained within a specified folder. The left-hand operand
specifies an object-valued property or an expression that results in a single object value. The right-hand
operand identifies the folder in one of the following forms:
•The folder ID
•The full path name of the folder
INSUBFOLDER can be used only on subfolders that have the Folder.Parent property set to the parent of the
folder (direct containment). The INSUBFOLDER operator will not recognize a subfolder linked to a parent by
referential containment (a ReferentialContainmentRelationship object having the
ReferentialContainmentRelationship.Tail property equal to the subfolder and the
ReferentialContainmentRelationship.Head property equal to the parent folder).
Note: Use of the INSUBFOLDER operator results in a complex query that can take a long time to execute.
Before deploying a solution that uses an INSUBFOLDER search across a large number of folders and
containees, ensure that this search behaves well on a large database and is properly optimized. The
database is not capable of properly optimizing all queries.

IN Operator
„
For multivalued properties (LIST cardinality)
„
value IN (constant1, constant2, …)
„
value IN (SELECT someproperty FROM …)
„
value IN
33
ADDITIONAL INFORMATION
The following formats are used for the IN operator:
•value IN listproperty
Where value is either a property name or a constant (<property_spec> | <literal>), and listproperty is a
property name (<property_spec>) of a property that has the cardinality of LIST. This format is used to search
a property that is of cardinality LIST. If the list has a value equal to value, the expression is true. Note that
you cannot use "value = listproperty" to compare a property of type LIST to a value. The IN operator must be
used.
•value IN (constant1, constant2, constant3,…)
Where constant1, constant2, constant3 are constants. This format is used to determine if value is equal to
one of the constants in the list. Note that when multiple items are enclosed in parentheses, the items must
be constants.
•value IN (SELECT someproperty FROM …)
This format is used to determine if value is one of the results returned by the subquery. Note that the
subquery must select only one property.

OBJECT Function
„
Create object constant to compare with an objectvalue property.
„
SELECT … FROM Folder WHERE Parent =
OBJECT('/root/sub1/sub1a')
34
ADDITIONAL INFORMATION
The Object function provides a means to create the effect of an object constant, which can then be
compared to an object-valued property or expression.
There are two logical forms of the Object function, one of which takes an argument of type GUID (Id), which
can either be a constant or a GUID-valued property, and the other of which takes a string argument, which
can be one of the following:
•The GUID constant (Id) of the object
•For Folder objects, the full path name of the folder
A <property_spec> for a property of datatype Id. An Object function can be used to compare objects to IDs,
which can be especially useful in joins

WHERE DocumentTitle = 'MyDoc'
35
ADDITIONAL INFORMATION
The INCLUDESUBCLASSES and EXCLUDESUBCLASSES operators, along with ISCLASS, are used to
limit results to specific classes or class hierarchies. INCLUDESUBCLASSES is the default. SQL query
examples are shown below.
The IsClass function acts as a filter for finding specific classes. The IsClass function is useful when querying
base classes WITH INCLUDESUBCLASSES, and the results must include objects that belong to one or
more particular subclasses of the base class.

Content Searches
„
A content (full-text) search
y Returns documents that contain the text you specify.
y Includes in the query words or phrases that might be stored
in objects or in their string properties.
y Is initiated by either a CONTAINS or a FREETEXT operator
in the SQL statement contained in SearchSQL.
„
To do a Content Search, you must
y Enable content-based retrieval (CBR) for the object and its
string properties.
y Index the documents.
50
ADDITIONAL INFORMATION
While the CONTAINS operator can search content in all properties or in a single property, the FREETEXT
operator can search content only in all properties. Note that attempting to specify a property name for
FREETEXT generates an exception.

Full-Text Joins

„
SELECT … FROM Document D LEFT OUTER JOIN
VerityContentSearch CS ON
D.This=CS.QueriedObject WHERE CONTAINS(*,'text')
OR D.Creator = 'Frank'
51
ADDITIONAL INFORMATION
Whenever a CONTAINS or FREETEXT clause is used, a join is performed on the (internal) ContentSearch
or VerityContentSearch classes.
Note: Instances of the ContentSearch or VerityContentSearch classes cannot be retrieved. However, the
properties of these classes are defined in the metadata for a RepositoryRow object.
The join is necessary because when a query with a full-text search is executed, the full-text search is done
first, and then the data from the full-text search is copied to a temporary database table that is referenced by
either the ContentSearch or the VerityContentSearch class name (both behave identically). The remainder of
the search statement is then executed against the repository, joining to this temporary table to access the
full-text search data.

Examples: a, about, above, be, because, few, for,
from, and so forth
56
ADDITIONAL INFORMATION
By default, the search engine does not look for certain common words, called Stop Words. When the index
is built, the stop words are not added to the collection so they can never be found.
If one or more words in your search requires a stop word, such as when you use the All or Near modifiers or
the AND operator between lines, the search will fail because these words never appear in the index. See
Autonomy K2 Stop Words for a list of these words.

ADDITIONAL INFORMATION
Simply entering one word as your search criteria causes the search engine to find various forms of that word
(stemmed variations). You can turn off stemming and require matching capitalization using double quotation
marks, look for patterns using the asterisk (*) as a wildcard character, or exclude a word using the
exclamation point (!) at the beginning.
When you enter two or more words, you can specify a relationship between those words.
Your object stores can be configured to use either Near or Sentence and Paragraph (Near is the default). If
your site uses Near, Sentence and Paragraph act like Near. If the specified object stores use Sentence and
Paragraph, then Near operates like Sentence and Paragraph. The words will qualify if they do not cross a

TimeLimit
y The time limit for the query, in seconds.

FullTextRowLimit
y Indicates the number of rows to pull from the full text index
prior to executing the remainder of the query.
y If a value is not supplied, the value of the
ObjectStore.FullTextRowDefault property (stored in the
GCD) is used.
59
ADDITIONAL INFORMATION
FullTextRowLimit
There is one row for each content element that is indexable, plus one more row for all CBR-enabled strings
of an object. Data from the full-text index is copied to a temporary table, and that table is then joined with the
remainder of the object store database to execute the query.
The FullTextRowLimit option enables you to control the maximum number of rows pulled from the full text
index.
For example, suppose a query has the clause "WHERE color = 'red' and CONTAINS(*, 'blue')". This query
might have a thousand rows that match "CONTAINS(*, 'blue')", but only ten rows that match "color = 'red'"
and "CONTAINS(*, 'blue')". If FullTextRowLimit is set to 500, then only 500 rows are pulled from the full text
index and written to the temporary table. Even though there are only ten rows that match the complete
WHERE clause, not all ten rows might be found because not all ten are necessarily in the 500 rows fetched
from the full text index.
If a value for FullTextRowLimit is supplied and this value is greater than the value of
ObjectStore.FullTextRowMax, then the value of ObjectStore.FullTextRowMax is used instead. The
FullTextRowMax property is present on the ObjectStore class to prevent queries from using too much
processing time and pulling an inordinate number of rows from the full-text index.

ADDITIONAL INFORMATION
• Assets managed in the Content Engine are protected and can be seen or modified only according to a
user's access rights.
• Each Content Engine server object has its own security, which controls a user's (or group's) access to that
object.
• Only securable objects have permissions that can be independently set. Non-securable objects are not
really non-securable; they are simply dependent on their parent object for their access rights (that is, they
are secured via the parent object’s permissions).
• A document with multiple content elements illustrates that you cannot independently control security on the
content element itself, unlike annotations, which are independently securable.
• A grantee is either an individual user or a group of users. A user can be a member of zero, one, or more
groups, and a group can contain zero, one, or more subgroups. A user account is defined on the Content
Engine server using tools provided by the directory service, for example, Microsoft Active Directory or Sun
ONE Directory Services.

Retrieve Object Permissions
Access Control Objects and Properties
„
Access rights for an object are determined by Access Control
List (ACL)
y Made up of one or more Access Control Entries (ACE)
y An ACE is represented by a Permission object
y An ACL is a Permissions collection (represents the full set of
ACEs)
„
Each ACE specifies:
y A security grantee (a user or group)
y A permission source (Example: Direct or Security Policy)
y “Allow” or “Deny” access type
y Access level
– Examples: “View Content”, “Full Control”, “Custom”
y Access rights (a more granular access level)
– Example: “Change state”
y Apply To
– Example: this object only or object and immediate children

ADDITIONAL INFORMATION
•Each ACE is represented by a Permission object, which establishes the access granted to a user or
group (the "grantee"), and contains a reference to the user or group being assigned the permission.
• A Permissions collection represents the full set of access control entries (ACEs) associated with an
object and forms the object's Access Control List (ACL).
Instructor Notes:
Emphasize the fact that an ACE corresponds to the API’s concept of a “Permission”, and that an ACL is a Permissions
collection.

ADDITIONAL INFORMATION
A newly-created object acquires its default permissions directly from its class.
The ClassDescription interface's get_DefaultInstancePermissions method returns the default permissions for
an object belonging to the class. You can use this method to determine if the class's permissions are
appropriate for your application or to display the default permissions in a user interface and allow the user to
modify the permissions when you are creating a new object of this class.
An object can also acquire permissions through inheritance and from a security policy.

What Is a Realm?
„
An abstract entity representing:
y A collection of security principals (users and groups) who
have access to objects controlled by the Content Engine
„
For Active Directory…
y A realm is the same as the Domain
„
For other directory services…
y A realm is the base object used to search the directory
y Details were specified during Content Engine installation

Instructor Notes:
Question (from Eric Adel):
On the Select users and groups window( under properties/security tab/add); We have two options Display
name and short name radio buttons. What is the difference, they both return the same results?
Answer (from Phong and Java Doc):
The searchedAttribute parameter identifies the User object attribute to be included in the search criteria, as
follows:
0 (or PRINCIPAL_SEARCH_ATTR_NONE) specifies that no attribute is included in the search criteria.
1 (or PRINCIPAL_SEARCH_ATTR_SHORT_NAME) specifies that the user's short name is to be included
in the search criteria.
2 (or PRINCIPAL_SEARCH_ATTR_DISPLAY_NAME) specifies that the user's display name is to be
included in the search criteria.
The difference between short name and display name is in the way you define user:
If you use Active Directory User and Group tool to open a user or group, you can see there is a name and
a Display name. They can be different; our users/groups have the same short name as the display name,
for example allen, amy. If you want to test, create a user with the name eric, and then set the display name
to something different, say Bruce the Great, then test it and you can see the difference.
