Hi,
I'm trying to create an axis2 module that is responsible to run validation
and respond to the requestor with a receipt message.
public class ValidateAndSendReceipt extends AbstractHandler {
@Override
public InvocationResponse invoke(MessageContext messageContext) throws
AxisFault {
//Validation logic goes here
MessageContext outMsgContext =
MessageContextBuilder.createOutMessageContext(messageContext);
outMsgContext.setEnvelope(buildReceiptEnvelope());
AxisEngine.send(outMsgContext);
return InvocationResponse.CONTINUE;
}
However I'm getting the following exceptions trying to execute my handler
described above:
[2014-01-23 20:26:59,693] ERROR - ServerWorker Error processing POST request

What is the possible reasons for these exceptions?
Thanks,
