How to use external Java API in Java Embedd inside BPEL

How to use external classes inside the BPEL in Java Embed Activity ? Any sample code availble ? Like i want to use log4j API inside BPEL.

No you dont have to change your startManagedServer.cmd/.sh everytime you need to have a Java Embedding activity. You only need it in case of using Log4J. As log4j requires a configuration xml viz log4j.debug.xml and log4j.dtd you need to let the soa managed server know about it. The best way to load this configuration files is using the JAVA_OPTIONS command during server startup.
Hope the explanation helps.

How to use the Java embedding activity in BPel

hi all,
How to use the java embedding activity in BPEL
pls can u provide sample example

1 Use [Oracle BPEL Process Manager Client Java API Reference|http://download-uk.oracle.com/docs/cd/B31017_01/integrate.1013/b28986/overview-summary.html] and especially [com.collaxa.cube.engine.ext|http://download-uk.oracle.com/docs/cd/B31017_01/integrate.1013/b28986/com/collaxa/cube/engine/ext/BaseBPELXExecLet.html]
Instead of System.Out.println use addAuditTrailEntry(java.lang.String message)
2. If you want to import a package write in code (Source View) of bpel process
+<bpelx:exec import="package_name"/>+ for example +<bpelx:exec import="java.util.regex.Matcher"/>+
example 1:
String bodyAsString;
StringBuffer myStringBuffer = new StringBuffer();
try {
bodyAsString = (String)getVariableData("BodyString");
addAuditTrailEntry("bodyAsString1: "+ bodyAsString);
Pattern pattern = Pattern.compile("goodDay");
Matcher matcher= pattern.matcher(bodyAsString);
while (matcher.find()) {
matcher.appendReplacement(myStringBuffer, "shitDay");
matcher.appendTail(myStringBuffer);
bodyAsString = myStringBuffer.toString();
addAuditTrailEntry("bodyAsString2: "+ bodyAsString);
} catch (Exception ex) {
addAuditTrailEntry("Failed+bodyAsString",ex.getMessage());
I put in code (Source View) the following
<bpelx:exec import="java.util.regex.Matcher"/>
<bpelx:exec import="java.util.regex.Pattern"/>
example2:
Object temp;
try {
temp = ((XMLElement)getVariableData("inputVariable","payload","/ns2:FiscalisMessage/ns2:Body")).getChildNodes().item(1);
setVariableData("AdjReceipt",temp);
addAuditTrailEntry("ok",temp.toString());
catch (Exception ex) {
addAuditTrailEntry("Failed :",ex);
I put in code (Source View) the following
<bpelx:exec import="oracle.xml.parser.v2.XMLElement"/>

How to use external jars in NW2004

Hello Experts,
can i use the same approach mentioned in the below Weblog for using the external jars in NW2004.
/people/bertram.ganz/blog/2008/11/24/how-to-use-external-jar-files-in-web-dynpro-development-components
and if not then what will be the best way to achieve it in NW2004.
Please provide your inputs on above.
Regards,
Siddharth

Hi Sidharth,
If you are using web dynpro DC perspective then you need to follow the following points to use the external jar files in it.
1. Create a external library project.
2. copy the external jars in the library folder os the projects.
3.) Select all the jars from the u201CLibrariesu201D folder, Right click and then select Development Component and click on Add to Public Part
4.Select the first Radio Button (Provides an API)and give some nameto it.
5. Repeat the step no 3 but now select the second radio button other than as selected in step no 4.
6. Now build your lirary DC.
7. Now create a j2ee DC project.
8. ) Expand the node DC Definition and Right Click on Used DC. Select Add Used DC.
9. Select the External Library DC with build time dependency.
10.Right click on the J2EE DC and then select Development Component followed by Build
11. Right click on the J2EE DC and then select Development Component followed by Deploy
now you can use both the libary DC and the j2ee DC in your web dynpro DC as used DC.
But if you have created a web dynpro project only(but not DC) than you can directly add the external jars in java build path
hope this will help
regards
Narendra

How to use External Tables

Hi, I want to know how to use external tables? The procedure i follow for SQL*Loader in my shell script is:
Call the sqlldr
Check return code
If return code = 2. get count of records from bad file and exit.
If return code != 0 and != 2 then exit as fatal error
If return code = 0 then continue.
But i don't understand how to use external table as it is not invoked and does not have a return code.

Hello,
What do you mean alogrithim, do you mean to invoke external table as you invoke sqlldr? You can generate external table script from sqlldr and use it to load data but you might have to modify the table name and datafile name . You can see if any bad file generated from sqlldr and if yes then you can generate external table (using sqlldr) or based on your bad file. May be if you can list what exactly you want in bullet points, then it will be easier to suggest you.

How to use the Worklist API from Java (classpath ??)

Hi all,
Sorry for a novice question but I couldn't find the way to go about this (probably because it's such common knowldge...)
I would like to try and use the Worklist API from my Java code in Eclipse, and according to the BPEL dev-guide I need to add an Import command for oracle.tip.pc.api.worklist. Where do I find these classes ?????
I guess I need to change my CLASSPATH but I couldn't find a single word about this in the BPEL dev-guide (chapter 17), BPEL installation guide or elseware.
thanks.

Hi all,
Ok now.
To summarize - I was trying the code from BPEL developer guide, chapter 17, page 40 for using the Worklist local API's.
Only after adding the following JAR's to the build path, was I able to compile it:
orabpel-common.jar
orabpel.jar
bpm-infra.jar
bpm-services.jar
So, these 4 JAR's are required for using the Worklist local API's (not a clue in the dev guide itself for this requirement though...)
Thank you very much for your help,
assaf.

How to use a Java Resource in my java source

Hello,
I need to know how to use my external JAR I loaded in the database using this line below:
CREATE OR REPLACE JAVA RESOURCE NAMED "MyJar" USING BFILE (BFILE_DIR,'MyExternal.jar');
In fact, I have a Java file using this JAR, but I do not know how to tell to the java source that it have to use this JAR.
==========Java Source importing the Jar===================
package com.gemalto.ws.snmp;
import java.io.IOException;
import java.util.Vector;
import org.snmp4j.Snmp;
import org.snmp4j.smi.*;
import org.snmp4j.TransportMapping;
import org.snmp4j.transport.DefaultUdpTransportMapping;
import org.snmp4j.CommunityTarget;
import org.snmp4j.mp.SnmpConstants;
import org.snmp4j.PDU;
import org.snmp4j.event.ResponseEvent;
public class SNMPAgent
==========================
Could you give the SQL request or loadjava command line permitting to do use my java resource file?
Thks

The JAR is already load by using CREATE JAVA RESOURCE ... or "loadjava -resolve –force -user p/p@SID –genmissing -jarasresource MyJar.jar"
If we can create a resource by SQL or loadjava, how can I use it in my java code?

Using External java within web dynpro DC

Hi
I'm new in web dynpro and I'm facing a problem.
I'm doing a web dynpro DC application and I want to use some external java classes I have created into my DC. But I don't really know how to do it, I tried EJB but I don't exactly how it works.
by the way, I was using a stand along web dynpro before and this worked fine, I just needed to create a package within my web dynpro project with all my class architecture to have them directly. but now with the DC stuff, it's not the same at all. so please help
thanks

Hi
Better you create a Java Development component and add all your java classes to that DC and build it.
Create a webdynpro DC to develop front end and add the java DC in used DC's of your Webdynpro DC.
This is the way you can use the java classes effectively with out redundancy.
If you create a package inside a normal webdynpro project, then you can not reuse them later in other webdynpro proj
Go with SAP component model by creating 2 development components one for java and other for webdynpro and define the reusability (Used DC's) in DC Metadata.

Setting bpel variable using external java code

Hi all
I would like to ask if there is a way to set bpel process variable during process execution from external java code using java api without using java embedding code?!!
Thnx in advance

Hi, I wanna to know if it is possible at all to edit/update value of variables in a process instance via external java code?
In fact I don't believe that we can set a variable remotely using java APIs.Am I right?
For example,is it possible to change the value of a field in the user task form(that is sent to a user to fill and complete the task)?

Hi,
I think you should not load the jar as java resource.
And I think there is no need to tell to the java source that it have to use the JAR. It will automatically look for the library.
You should load the jar file using the loadjava utility.
If it can helps, here is how I proceed :
/* LOAD .JAR FILE */
loadjava -user your_user/password@host -resolve -verbose -nodefiner C:\jdevstudio1013\jdev\lib\your_lib.jar
/* LOAD PROGRAM */
loadjava -user your_user/password@host -resolve -verbose -nodefiner C:\jdevstudio1013\jdev\mywork\your_program.java
/* CREATE THE PL/SQL FUNCTION */
create or replace procedure your_function(arg1 in varchar2, arg2 in varchar2) authid current_user as
language java name 'your_program.your_function(java.lang.String, java.lang.String)';
/* EXECUTE */
select your_function('hello','world') from dual;

How to use another java program to stop this running prpgram???

Dear Sir:
I have following code and I run it success,
import java.util.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.*;
public class CertainAndRepeatTime{
public static void main(String[] args) throws IOException{
    int delay = 1;
    Timer timer = new Timer();
    ActionListener actionListener = new ActionListener() {
        public void actionPerformed(ActionEvent actionEvent) {
          System.out.println("Hello World Timer");
    System.out.println("What do you want (Certain time or Repeat time)?");
    System.out.print("Please enter \'C\' or \'R\' for that: ");
    BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
    String ans = in.readLine();
    System.out.print("Please enter ans=" + ans + " IsTrue= " + (ans.equals("R") || ans.equals("r")) +"\n");
    if (ans.equals("C") || ans.equals("c")){
      //System.out.println("This line is printed only once start...");
      timer.schedule(new TimerTask(){
        public void run(){
          System.out.println("This line is printed only once.");
      },delay,1);
    else if(ans.equals("r") || ans.equals("R")){
        timer.scheduleAtFixedRate(new TimerTask(){
          public void run(){
            System.out.println("This line is printed repeatedly.");
        },delay, 1000);
      while(true){
           //System.out.println("Charles print This line is printed repeatedly.");
      } //This will make your main thread hang.
    else{
      System.out.println("Invalid Entry.");
      System.exit(0);
    System.exit(0);
}But I hope to use another java program to stop it when it is running instead of pressing CRTL + C to stop it.
How to do it??
Any example??
Thanks a lot!!

Sorry, I think i did not express cearly. It is my fault.
I re-write my requirements again:
I have
Class AAA1.java,
Class AAA2.java,
Class AAA3.java,
Class AAA20.java...
etc
they all look like the program I posted first time,, once executed, they will run for ever, and they will be stopped until I press CRTL + C;
Now I hope to use another java class StopProgram.java to stop them 1 by 1 or at once instead of pressing CRTL + C;
In this case, how to code this StopProgram.java ??
Thanks
