Axis2 web service invocation error

Question

I tried to create a simple tester for my service and I get this exception:

Exception in thread "main" org.apache.axis2.AxisFault: java.lang.UnsupportedOperationException: An access occurred that is not valid.
    at org.apache.axis2.util.Utils.getInboundFaultFromMessageContext(Utils.java:531)

    at pinservice.PinOperationStub.changePin(PinOperationStub.java:496)
    at pinservice.PinOperationTester.main(PinOperationTester.java:22)

any help on troubleshooting this error or thoughts on why this happens ?

Answer 1

It is an incorrect use of message receiver (in-out and in-only). Make sure to update services.xml file with correct configuration. More details available in below link with simple example.
