[AXIS2] : Null Pointer Exception in Stub

[aashish <aa...@yahoo.com>]

hi all,
i get anull pointer exception at 
System.out.println("transport is 
"+_messageContext.getTransportOut().getSender().toString());
in my stub. (stub generated using Axis2  Code Generator plugin, by passing the 
WSDL)
and the error in System.Err is 
org.apache.axis2.AxisFault: The system cannot infer the transport

  
information from the 
 http://212.34.1.123:13000/Directory/services/ABCService URL.

lient.java:165) 


The transportOut is somehow being set to null.

However i can use the same stub to call the same service from another 
application.
