Using embedded Java in BPEL 2.0

I have found a lot of write ups but am having difficulty.
My problem is a failure to deploy by composite. I get the message below:
Redeploying on /Farm_soadev_domain/soadev_domain/AdminServer ...
Redeploying on "/Farm_soadev_domain/soadev_domain/AdminServer" failed!
There was an error deploying/undeploying composite on AdminServer: Error occurred during deployment of component: formatDate to service engine: implementation.bpel for composite: formatData: ORABPEL-05250
Error deploying BPEL suitcase.
error while attempting to deploy the BPEL component file "E:\Oracle\Middleware\user_projects\domains\soadev_domain\servers\AdminServer\dc\soa_c8abc64b-8475-4479-b54b-b36e4f44c37a"; the exception reported is: java.lang.RuntimeException: failed to compile execlets of formatDate
This error contained an exception thrown by the underlying deployment module.
Verify the exception trace in the log (with logging level set to debug mode).
To simplify the issue I have reduced my code snippet to:
/*Write your java code below e.g.
System.out.println("Hello, World");
String testOne = "Hi Mom";
The embedded section looks like:
    <extensionActivity>
      <bpelx:exec name="decodeBinary" language="java">
        <![CDATA[
/*Write your java code below e.g.
System.out.println("Hello, World");
String testOne = "Hi Mom";]]>
      </bpelx:exec>
    </extensionActivity>

I read the blog post here
Embedding Java in BPEL process
Based on that I created this test class to help write code:
The bolded code is the snippet I actually want to implement when I can solve the problem above.
package com.f17.customfunction;
import com.collaxa.cube.engine.ext.bpel.v1.nodes.BPELXExecLet;
public class codeTyper extends BPELXExecLet {
    public codeTyper() {
        super();
    public void exec(){
     // below code gets pasted in here
String input = (String)getVariableData("testfile");
oracle.soa.common.util.Base64Decoder Decoder = new oracle.soa.common.util.Base64Decoder();
try {
byte[] decodedByteArray = oracle.soa.common.util.Base64Decoder.decode(input.getBytes());
setVariableData("compANDstore_merge_InputVariable.AusCreditCollection/ns2:AusCredit/ns2:fileData,decodedByteArray",decodedByteArray);
} catch(Exception e) {

Embedded Java And BPEL

Hi All
I need some very urgent help. I had been working on TIBCO and XI till now and in a project currently using Oracle Fusion. I need to query a data from an LDAP service and post a collection of employees into a JMS Queue as an XML. Now I tried using Embedded java to query the LDAP service and that works fine and it returns me the employee details. I have an XSD file that represents how the data needs to be presented. I imported the XSD file into my project and created a variable of element type and chose the schema to be the XSD which I am pasting below. I tried all kinds of ways to populate the data but I always get a selection failure error.
I then just tried a simple setVariableData method to set the username and again i get the same error. How can I set the variable so that it returns me a collection back. Please help. I am pasting both the XSD as well as the java code that I tried to use. It would be great if someone could let me know what I have done wrong or is there any ways of doing this.
Thanks so much

addAuditTrailEntry(e);
I tried numerous things and today is the final day for my code completion. So i am in a bit of trouble. I just cant figure out what I have done wrong here. I have created a DOM document as you had suggested and then done a setVariableData onto the Variable_1 that i had created selecting the xsd that I had pasted in my previous post as the schema for the variable. I have the namespace set corretly as well. Any suggestions.
Thanks so much in advance

Embedded Java in BPEL and exception handling

Hello everybody,
i want to use some embedded java code in my BPEL process (bpelx:exec). This code would sometimes throw exceptions. How can i deal with these exceptions to control my BPEL process? I would like, in a sense, to do some catching of java exceptions but at the BPEL level... for example, my java code would throw an exception, that my BPEL process would "catch" and react the way i want. Is it possible to do that?
Thanks for your help!
Nicolas

you need to throw a com.oracle.bpel.client.BPELFault ..
from the code
* This class represents a standard fault that may be thrown by the server
* during run-time. A BPEL fault has defined, minimally, a QName that
* corresponds to the fault name (there are several standard faults that
* are supported, please refer to Appendix A - Standard Faults in the BPEL
* 1.1 specification for a complete list).
* <p>
* This class can only be used from within a <code>bpelx:exec</code> activity;
* the <code>throw</code> activity can be used from BPEL code.
* <p>
* Additional information (such as a fault variable) can be passed through
* as a part. Currently, internal system errors populate error codes and
* summary messages via parts.

How to Debug a Java Project in Eclipse using Tomcat6.0

Hi
Can anybody help me with the following questions.
1.How to create a java project in eclipse(I am using jsp,servlets,jsf,spring,jasper,struts).
2.How to debug my application in Eclipse Europa by putting break points.
3.how should i add Tomcat6.0 to my project in order to debug my application so that i can put break points while running the applications and observe the values.
Thanks
Bala

You may find this tutorial useful regarding to JSF, Eclipse and Tomcat: http://balusc.blogspot.com/2008/01/jsf-tutorial-with-eclipse-and-tomcat.html
To put breakpoints, just doubleclick on the left gray rule of the code, you'll get blue bullets at the left rule, indicating a break point. Run Tomcat in debug modus (rightclick Tomcat � debug). Use the Eclipse debug perspective to step in the code (window � open perspective � debug).

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"/>

Pass the BPEL Input Payload to Embedded Java Program

Please let me know how can we pass the Input to a BPEL process to the embedded Java Program.
Requirement:
To pass the payload recieved by the BPEL process to a Java method using embedded java activity where we can parse/modify this payload
I tried this approach
Object obj = (Object)getVariableData('variableName');
//call to java method with obj as argument
//In java method
XMLElement xmlElement = (XMLElement)obj;
thereafter I am trying to read the nodes of this element but this is not working.
Please point me to any document/tutorial/examples in this context.
Thanks

Hi
the getVariableData() method returns a org.w3c.dom.Element object (10.1.3 version).
So I believe you should use something like:
Object obj = (Object)getVariableData('variableName');
//call to java method with obj as argument
//In java method
org.w3c.dom.Element xmlElement = (org.w3c.dom.Element)obj;
And to read a node use this:
org.w3c.dom.Node node = xmlElement.getFirstChild().getNodeValue();
However I never tried getVariableData('variableName'), I tried getVariableData('variableName','partName','query') so I don´t know the diferences between these two methods, but I hope this helps you.

Hi,
I am facing an issue as below in Java embedding activity of BPEL process in 10g...
Could not invoke: "GTM servlet URL" with verb: POST and context: null
and the code in java embedding activity is as below...
// create a new rest invoker stub
RestInvocation invocation = new RestInvocation();
org.w3c.dom.Element callOtm_process_InputVariable = (org.w3c.dom.Element)getVariableData("Variable_GTMTransmission");
// get the result el - so we can derive the namespace needed

How to debug XSLT in BPEL

Hello,
I am getting issue in BPEL code while executing XSLT file. If I have performed the 10 mappings in XSLT file and one of them has error in assigning source to target values. Its just mentioned that following XSLT file has error and doesn't mention the exact line where the error has been occured.
Any best way to debug XSLT so it can provide the exact error ?
Thanks

Yes, It is the part of BPEL. But I am using Oracle SOA 10 g. Can you please elaborate how can I debug the XSLT is BPEL using BPEL Console in 10g ?? Actually when I am getting issue in XSLT, it's hard to find out where I am having the problem. If I am performing more than 20 transformation in XSLT file it's impossible for me to highlight the exact line where I have an issue.
Thanks

Hi ,
In your java project frm jdev..right click and choose general and then choose deployment profiles and then choose Jar ..and then give some appropriate name(abc) and then click ok.
Then under resources file u get a abc.deploy file right click and say deploy to jar ..u will find the jar in that director.Now include this jar in your prjct libraries.
have a look at the link http://niallcblogs.blogspot.com/search/label/embedded%20Java
