Simon Laws updated TUSCANY-372: ------------------------------- Attachment: helloworld6-notworkingsample.tar The example that causes the null pointer. > Null pointer for axis2/tomcat example where the service interface/operation > takes no parameters > ----------------------------------------------------------------------------------------------- > > Key: TUSCANY-372 > URL: http://issues.apache.org/jira/browse/TUSCANY-372 > Project: Tuscany > Type: Bug > Components: Java SCA Axis Binding > Versions: Java-M1 > Environment: Fedora Core 5 > Reporter: Simon Laws > Priority: Minor > Attachments: helloworld6-notworkingsample.tar > > This is based on a check out from last week so I will give it a go on the > latest release but lest I forget the details. I have an example (attached) > which simply calls a remote component via axis2/web services. The implemented > operation takes no parameters and causes a null pointers exception down in > the Axis code on the server side where the request message is being unpacked > [1]. I copied the example and changed the operation signature to include a > single string parameter (also included) and all was well. Nothing else, as > far as I can tell, changed between the two versions of the sample. > [1] > [EMAIL PROTECTED] helloworld6client]$ ./run.sh > Exception in thread "main" org.osoa.sca.ServiceRuntimeException: > org.apache.axis2.AxisFault: null; nested exception is: > java.lang.NullPointerException > at > org.apache.tuscany.binding.axis2.externalservice.Axis2ServiceInvoker.invoke(Axis2ServiceInvoker.java:56) > at > org.apache.tuscany.core.extension.ExternalServiceTargetInvoker.doInvoke(ExternalServiceTargetInvoker.java:84) > at > org.apache.tuscany.core.extension.ExternalServiceTargetInvoker.invokeTarget(ExternalServiceTargetInvoker.java:79) > at > org.apache.tuscany.core.extension.ExternalServiceTargetInvoker.invoke(ExternalServiceTargetInvoker.java:93) > at > org.apache.tuscany.core.wire.impl.InvokerInterceptor.invoke(InvokerInterceptor.java:39) > at > org.apache.tuscany.core.wire.jdk.JDKInvocationHandler.invoke(JDKInvocationHandler.java:112) > at $Proxy13.getResponse(Unknown Source) > at > org.sample.helloworld.HelloWorldClient.main(HelloWorldClient.java:28) > Caused by: org.apache.axis2.AxisFault: null; nested exception is: > java.lang.NullPointerException > at > org.apache.axis2.description.OutInAxisOperationClient.execute(OutInAxisOperation.java:287) > at > org.apache.tuscany.binding.axis2.externalservice.Axis2OperationInvoker.invokeOperation(Axis2OperationInvoker.java:78) > at > org.apache.tuscany.binding.axis2.externalservice.Axis2ServiceInvoker.invoke(Axis2ServiceInvoker.java:53) > ... 7 more > Caused by: java.lang.Exception: org.apache.axis2.AxisFault: null; nested > exception is: > java.lang.NullPointerException > at org.apache.axis2.AxisFault.makeFault(AxisFault.java:318) > at > org.apache.tuscany.binding.axis2.entrypoint.WebServiceEntryPointInOutSyncMessageReceiver.invokeBusinessLogic(WebServiceEntryPointInOutSyncMessageReceiver.java:83) > at > org.apache.axis2.receivers.AbstractInOutSyncMessageReceiver.receive(AbstractInOutSyncMessageReceiver.java:37) > at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:454) > at > org.apache.axis2.transport.http.HTTPTransportUtils.processHTTPPostRequest(HTTPTransportUtils.java:284) > at > org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:136) > at > org.apache.tuscany.binding.axis2.entrypoint.WebServiceEntryPointServlet.doPost(WebServiceEntryPointServlet.java:81) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:709) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) > at > org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) > at > org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) > at > org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) > at org.apache.tuscany.tomcat.TuscanyValve.invoke(TuscanyValve.java:87) > at > org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) > at > org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) > at > org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) > at > org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) > at > org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) > at > org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) > at > org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) > at > org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80) > at > org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) > at java.lang.Thread.run(Thread.java:797) > Caused by: java.lang.NullPointerException > at > org.apache.tuscany.binding.axis2.databinding.AxiomHelper.toDataObject(AxiomHelper.java:164) > at > org.apache.tuscany.binding.axis2.databinding.AxiomHelper.toObjects(AxiomHelper.java:68) > at > org.apache.tuscany.binding.axis2.databinding.SDODataBinding.fromOMElement(SDODataBinding.java:42) > at > org.apache.tuscany.binding.axis2.entrypoint.WebServiceEntryPointInOutSyncMessageReceiver.invokeBusinessLogic(WebServiceEntryPointInOutSyncMessageReceiver.java:50) > ... 22 more > at org.apache.axis2.AxisFault.<init>(AxisFault.java:159) > ... 10 more -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
