[jira] Resolved: (AXIS2-2775) nullpointer by invoking web service
and RPCMessageReceiver problem
[ https://issues.apache.org/jira/browse/AXIS2-2775?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Deepal Jayasinghe resolved AXIS2-2775.
--------------------------------------
Resolution: Fixed
First you do not need to get the session context as you have done , you can just get the session context from the MessageContext.
MessageContext mctx =MessageContext.getCurrentMessageContext();
TransportListener listener = mctx.getTransportIn().getReceiver();
SessionContext session = listener.getSessionContext(mctx);
MessageContext.getCurrentMessageContext().setSessionContext(session);
And other thing is you have only valid session context only if you have deploy your service in transport session. So please try to do the following,
First deploy your service in transport session
Get the session context from the messagecontext.
MessageContext.getCurrentMessageContext().getSessionContext();
I will resolve the issues , since the error is due to user code. Please try to follow the steps that I mentioned and please re-open the issue if the issue is still there.
