Error while making webservice call

Question

I am accessing a webservice exposed by some other guy as a client using axis2 and I have made a wrapper method for abcStub .java (Stub java file made by running some batch) and tried to instantiate the Stub file inside the wrapper java file. But i get following errors:

    INFO: ERROR org.apache.struts.actions.DispatchAction  - Dispatch[/remittanceTransaction] to method 'remTransApprove' returned an exception

I think there must be problem with this

org.apache.neethi.PolicyEngine.getPolicy(Ljava/lang/Object;)Lorg/apache/neethi/Policy; 

or may be im wrong. Either way, dunno how to fix. Would be of much help if anyone knew of faced/solved this before.

I got this while making following call:

public String getAppDeclWrapper(String session, String parentAgent, String mirsTxnNo, String strReason, String isApprove, String modifiedBY){ String returnString = null;
try {

         mtmrsLogger.info("Entering into Approve Decline procedure, Starting to send Status to MIRS");
               MIRSRemittanceServicesStub stub  = new MIRSRemittanceServicesStub(); //Error occurs at this line

               ApproveDecline approvedEcline = new ApproveDecline();
               ApproveDeclineResponse approveResponse =  new ApproveDeclineResponse();
               approvedEcline.setCParentAgent(parentAgent);
               approvedEcline.setMirsSession(session);
               approvedEcline.setModifiedBy(modifiedBY);
               approvedEcline.setRefNo(mirsTxnNo);
               approvedEcline.setStrReason(strReason);
               approvedEcline.setIsApprove(isApprove);

Answer 1

My guess is you have multiple versions (or invalid version) of PolicyEngine on your classpath. I think you are running inside a servlet engine. Try following code to determine where this version is stored and fix it:

org.apache.neethi.PolicyEngine.class.getProtectionDomain().getCodeSource().getLo‌​cation()
