Exception Handling in BPEL

Question

Guys,
I have exposed the following class as Web-Service, using Axis.
public class ExceptionCreator {
public ExceptionCreator(){
public ReturnObject generate(boolean flag) throws CustomException{
if(flag){
throw new CustomException("This is a custom exception");
}else{
return new ReturnObject(1,"NO EXCEPTION");
where ReturnObject is a simple JavaClass with two member variables id & name and CustomException is a class extended from Exception superclass in Java.
Using axis, writing appropriate serializers in wsdd, I created a web-service out of this and imported the WSDL from Axis as a Partner Link in BPEL.
If I pass true as Input and if I specify "{http://schemas.oracle.com/bpel/extension}remoteFault as faultName in the catch, the exception does get caught. However, I am unable to access the details of the same which looks like below:
[2005/09/26 18:44:11] "{http://schemas.oracle.com/bpel/extension}remoteFault" has been thrown.
<remoteFault xmlns="http://schemas.oracle.com/bpel/extension">
<part name="code">
<code>Server.userException</code>
</part>
<part name="summary">
<summary>when invoking endpointAddress 'http://kingfisher:9080/axis/services/ExceptionCreatorSewrvice', com.misys.equationcore.tutorials.CustomException: This is a custom exception</summary>
</part>
<part name="detail">
<detail>AxisFault faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException faultSubcode: faultString: com.misys.equationcore.tutorials.CustomException: This is a custom exception faultActor: faultNode: faultDetail: {http://kingfisher:9080/axis/services/ExceptionCreatorSewrvice}fault:<exceptionMessage type="soapenc:string">String CustomException Constructor</exceptionMessage> {http://xml.apache.org/axis/}hostname:kingfisher</detail>
</part>
</remoteFault>
I am trying to access the contents of this fault in a Assign activity where I want to display the actual java exception as output.
Any clues as to how I can access the same?
Thanks in advance,
~Soumen.

Currently in My bpel ,when any error occurs i have to send a error notification by Email .
Currently i have exposed the email service which shuts emails and write a file with errored Message.Seeing your use case I will suggest you to use fault handling framework (fault policy). Fault handling framework should be used where you need generic error handling framework which handles all the faults occured in any composite component. Generally BPEL catch block should be used to propagate error info/fault back to the client/to fault handling framework or to consume an error
