1. Database Setup
Login as SYS

default tablespace users
temporary tablespace temp;
grant connect, create session, create procedure, create public synonym to webutil;
grant resource, connect to webutil;
grant execute on dbms_lob to webutil;

grant execute on webutil_db to public;
set serveroutput on
declare
a boolean;
begin
a:=webutil_db.closeblob(1);
If a then
dbms_output.put_line('webutil/blob setup '||'TRUE');
else
dbms_output.put_line(' webutil/blob setup '||'FALSE');
end if;
end;
2. copy jacob.jar and copy frmwebutil.jar to ORACLE_HOME/forms/java directory.
Make sure you can download these using the below
http://machinename.com/forms/java/jacob.jar
http://machinename.com/forms/java/frmwebutil.jar
3. Create directory webutil under [OraHome]/forms/webutil and .
copy jacob.dll , JNIsharedstubs.dll, d2kwutil.dll

5. In the default.env update
WEBUTIL_CONFIG=/opt/oracle/product/10gas/forms/server/webutil.cfg
CLASSPATH=c:\temp\webutil\lib\frmwebutil.jar;c:\"Program
Files"\Java\j2re1.4.2_06\lib\rt.jar (Include rt.jar)
Also include C:\Dev10g\forms\java\ frmall.jar
6. Settings for

8. Sign jacob.jar ( Not mandatory )
Open a DOS command prompt.
Add [OraHome]\jdk\bin to the PATH:
set PATH=[OraHome]\jdk\bin;%PATH%
Sign the file, and check the output for success:
[OraHome]\forms\webutil\sign_webutil [OraHome]\forms\java\jacob.jar
[Previously this point stated that frmwebutil.jar also needed to be signed. This is no longer
necessary and should not be done.]
9. Start Forms Builder and connect to a schema in the RDBMS used in step (4).
Open webutil.pll, do a "Compile ALL" (shift-Control-K), and generate to PLX (Control-T).
If the PLX is not generated, the Webutil.pll library would have to be attached with
full path information to all forms wishing to use WebUtil. This is NOT recommended.
10. Create a new FMB.
Open webutil.olb, and Subclass (not Copy) the Webutil object to the form.
There is no need to Subclass the WebutilConfig object.
Attach the Webutil.pll Library, and remove the path.
Create a new button on a new canvas, with the code
show_webutil_information (TRUE);
in a WHEN-BUTTON-PRESSED trigger.
Compile the FMB to FMX, after doing a Compile-All (Shift-Control-K).
11. Under Edit->Preferences->Runtime in Forms Builder, click on "Reset to Default" if
the "Application Server URL" is empty.
Then append "?config=webutil" at the end, so you end up with a URL of the form
http://server:port/forms/frmservlet?config=webutil
12. Compile the webutil.pll and attach it to the fmb. Compile it

Debugging
1. Clear the browser cache and enable the jinitator / sun java plugin.
For Sun Java Plugin
Start ->Settings ->Control –Panel->Java->Advanced ->Show Java Console
Debugging ->Select All
Clear the plugin cache and once again access the URL. Make sure all the dlls,jar files
are getting downloaded.

4. Read / Write - image file
----------------------------The code was not erroring out, but the image was not getting copied in the
image item .
Cause
----transfer.appsrv.workAreaRoot=<name of the temp directory >
transfer.appsrv.accessControl=TRUE was not specified in the webutil.cfg file
The root of the location in which WebUtil can store temporary files
uploaded from the client.
While Writing Image file ( remember its the client to which the image
is written to ).
Example
client_image.write_image_file('d:\myimg\','GIF','CTRL.MY_IMG',
maximize_compression, original_depth);
Then ensure that on the thin client , there exist a directory called as "myimg" in the D drive .
One should watch out for the error in the console or the log depending on how
the logging has been set to .In case if the directory does not exist on the
client message appears that cannot create a file ...
These are the steps that occurs 1) WebUtil creates a working directory that is private to the user
on the applciation server using the value of transfer.appsrv.workAreaRoot
This is that <ipaddress>\<ntuser name> directory
2) The basic forms Write Image file is used to extract a temporary copy
of the image into that directory.
3) The image is downloaded into the client machine and saved as the name
that you specified as the filename in the write_image_file command.
4) The temporary copy of the image held in the workAreaRoot on the Appserver
is cleaned up.
4) Client_host - The command is supposed to run the executable on the client .
But if you are trying to call an exe which is not in the path , you will not
get any error.

otherwise there is an error message when opening the canvas in the new created fmb
6. Post a thread in otn forum
7. Last option is to send an email to info@alexys.us We will look into it and can give the
