How to call a web Service from Oracle Applications?

Question

Hi friends,
I've posted this question on OA Framework forum , but may be it's more appropiated put it here. Sorry for do it again:
It's about how to call a web service from a Form or a .sql (via Request) in Oracle Applications:
Could you please explain here the detailed steps (with code example if it's possible) to invoke a webservice from Oracle Applications?.. how did yo do it...?
I've read differents posts here and the 33097.1 metalink note (by the way, the first recommended link in this note is broken...), but there are lots of theorical concepts and no real examples to see how/from where invoke the WS
I'll have to call one webservice (I suppose the customer will give me the interface implementation)...but I've never did it with Applications so that's why I ask you for all the detailed steps...
I work with Forms 6i, Apps 11.5.10.2 and DB 9.2.0.7.
Thanks a lot.
Jose.

Hello Jose,
I did using java program to call BPEL web services in 11.5.10.
I pasted below the metalink note for your reference (Note:250964.1)
The idea is first write a java program to call the webservice (in my case it is calling an BPEL web service, so this may not help directly), test it.
Then port the java program as specified in the note, so that you could call your web service through concurrent manager scheduler.
Is this ok?
Thanks
Arun.

How to register and create a Java concurrent program for Oracle Applications
Release 11i
Solution
========
1. Create your Java Concurrent Program (JCP) , using a text editor.
/*===========================================================================+
| Concurrent Processing Sample Code |
| |
| FILENAME |
| Hello.java |
| |
| DESCRIPTION |
| Sample Java concurrent program |
| About the simplest possible program, just writes a message to the |
| logfile and output file. |
| |
| HISTORY |
| $Log$ |
| |
+===========================================================================*/
package oracle.apps.fnd.cp.sample;
import oracle.apps.fnd.cp.request.*;
public class Hello implements JavaConcurrentProgram {
public static final String RCS_ID = "$Header$";
public void runProgram(CpContext ctx) {
ctx.getLogFile().writeln("-- Hello World! --", 0);
ctx.getOutFile().writeln("-- Hello World! --");
ctx.getReqCompletion().setCompletion(ReqCompletion.NORMAL, "");
=======================================
End Sample
=======================================
2. Create a sample directory under $JAVA_TOP:
$ mkdir $JAVA_TOPoracle/apps/fnd/cp/sample
3. Copy Hello.java into $JAVA_TOP/oracle/apps/fnd/cp/sample:
$ cp $HOME/Hello.java $JAVA_TOP/oracle/apps/fnd/cp/sample
4. Compile your java program:
javac $JAVA_TOP/oracle/apps/fnd/cp/sample/Hello.java
5. Test at the command line with following syntax:
jre -Ddbcfile=$FND_TOP/secure/your_dbc_file.dbc \
-Drequest.outfile=./outfile \
oracle.apps.fnd.cp.request.Run \
oracle.apps.fnd.cp.sample.Hello
6. Register your custom java concurrent program with Oracle Applications.
a. Navigate: Concurrent > Program > Executable
b. Enter details into the form
Executable: JCPHELLO
Shortname: JCPHELLO
Application: Application Object Library
Execution Method: Java Concurrent Program
Execution File Name: Hello (Insert a name that does not contain space or period)
Execution File Path: oracle.apps.fnd.cp.sample
c. Save the details
d. Navigate: Concurrent > Program > Define
e. Enter details into the form
Program Name: JCPHELLO
Program Shortname: JCPHELLO
Application: Application Object Library
Executable: Choose JCPHELLO from LOV
Executable Options :
f. Save the details
7. Add this new concurrent request to your responsibility request group.
a. Navigate > Security > Responsiblity > Request
b. Query System Administrator
c. Add new row and choose TestJava
d. Save the changes.
8. Run your new Hello Java Concurrent Program
Navigate: Request > Run
