Spring Service Component
The Spring Framework is a lightweight container using “plain old Java objects” (POJOs)
WebLogic SCA enables the usage of the Spring Framework and to expose components as SCA services and references
SCA extends Spring framework capabilities
•
Publish spring beans as SCA component services
•
Provide references to Spring beans wired to services of other components
Following types of component integrations are supported
•
Java components to WSDL components
•
WSDL components to Java components
•
Java components to Java components

<sca:service> Element
Declares a Spring bean that SCA exposes as a service
Takes the following attributes:
•   Name
§   the name of the service (required)
•   Type
§   The fully qualified Java type of the Java class to be exposed as an SCA service
(required)
•   Target
§   The bean to be exposed as a service (required)

<sca:reference> Element
Declares a Spring bean representing an SCA service external to the Spring application context
Takes the following attributes:
•   Name
§   The name of the reference (required)
•   Type
§   The fully-qualified Java type of the interface or class representing the remote service
(required)
•   Default
§   The target bean for the reference if none is specified (optional)

Using the Predefined Beans
The following spring beans are predefined in SOA Suite:
•   headerHelperBean – for getting an setting header properties
•   instanceHelperBean – for getting Instance ID of composite and component, name of the Spring service component
•   loggerBean – for providing context-aware logging message
You can also define your own Spring beans globally => see use case 3

Five Cool Use Cases for the Spring component of the Oracle SOA Suite

Case 1 – Configuration: Within SOA Suite
Use Case: Need configuration properties which are changeable at runtime
Within a SCA Composite preferences can be declared
•
Has to start with bpel.preference
Use ora:getPreference('greetingMessage') from within BPEL
Restriction : Only scalar values are supported! Can only be accessed from a
BPEL component.

Case 1 – Configuration: Within SOA Suite
Values can be changed through System MBean Browser in EM
§   oracle.soa.config > Server : soa_server1 > SCAComposite > your_project >
SCAComposite.SCAComponent > your bpel_process

Case 3 – NoSQL: What is NoSQL?
NoSQL is a new class of databases
They don‘t use the relational data model and thus don‘t use SQL
Tend to be designed to run on cluster
Schema-Less - Don‘t have a fixed schema, allowing to store any data in any record
Different types of NoSQL databases
•
Key/value
•
Column Family
•
Document
•
Graph

Case 3a – NoSQL: MongoDB Logging Bean
Define bean in the global spring context (custom predefined bean) so that logging is globally available
1.
Add the bean definition here
§   SOA_HOME/soa/modules/oracle.soa.ext_11.1.1/classes/ springse-extension-global-beans.xml
2.
Add the corresponding classes in either the lib or classes directory
3.
Run the ant script and restart server (more information in readme.txt
)

Summary
The Spring component is a nice way to extend the functionality of the SOA
Suite and the other service engines
Use cases for it are endless ….
Only use the Spring component if no out-of-the-box feature in the SOA
Suite exists
Make sure that you test the Java and Spring stuff externally first
Only Spring Framework 2.5 …
