Ali Sadik Kumlali commented on AXIS2-679: ----------------------------------------- Oops! Second call has problem in either case. Here is the scenario again: ----------------------------------------------- - When I call serviceA, one of its methods calls stub of serviceB. Here is the last minute situations: ----------------------------------------------- - With the ServiceClient comming with 1.0 release: - First call to serviceA works well. - Second call causes the mentioned NPE at the server side which serviceA is deployed. - When modify the ServiceClient of 1.0 release; - First call to serviceA works well - Second call causes "org.apache.axis2.AxisFault: WSDoAllReceiver: Request does not contain required Security header" at the client side which serviceB.aar is deployed. At the server, there is no NPE. The SOAP has WS-Addressing tags, but not WS-Security tags. > Calling a service from within another service causes NPE > -------------------------------------------------------- > > Key: AXIS2-679 > URL: http://issues.apache.org/jira/browse/AXIS2-679 > Project: Apache Axis 2.0 (Axis2) > Type: Bug > Components: core > Versions: 1.0 > Environment: WinXP Pro, JDK 1.4, Tomcat 5.5 > Reporter: Ali Sadik Kumlali > Assignee: Deepal Jayasinghe > > Here is my scenario: > 1) I have serviceA.wsdl and serviceB.wsdl. > 2) I generate skeletons and stubs with WSDL2Java > 3) I have serviceA.aar which has serviceB.wsdl's stub > 4) When I call serviceB's stub from a class found in serviceA.aar I get the > following error: > ---------------------------------------------------------------- > java.lang.NullPointerException > at > org.apache.axis2.context.ServiceGroupContext.getServiceContext(ServiceGroupContext.java:59) > at org.apache.axis2.client.ServiceClient.<init>(ServiceClient.java:101) > at > com.mycompany.service.test.account.AccountServicesStub.<init>(AccountServicesStub.java:79) > ---------------------------------------------------------------- > I founded that "unassinged parent" caused the NPE. If the service is already > registered in axisConfig it doesn't enter in the code that assings a parent > to the service. Also, it doesn't uses the parent of the registered service. > The code causes NPE is here: > ---------------------------------------------------------------- > // org.apache.axis2.client.ServiceClient > public ServiceClient(ConfigurationContext configContext, > AxisService axisService) throws AxisFault { > ... > // If the service is already registered, it doesn't enter > // here so there will be no parent. > if (this.axisConfig.getService(this.axisService.getName()) == null) { > this.axisConfig.addService(this.axisService); > } > ServiceGroupContext sgc = new ServiceGroupContext(this.configContext, > (AxisServiceGroup) this.axisService.getParent()); > this.serviceContext = sgc.getServiceContext(this.axisService); > } > ---------------------------------------------------------------- > I made the following change and it worked: > ---------------------------------------------------------------- > // org.apache.axis2.client.ServiceClient > public ServiceClient(ConfigurationContext configContext, > AxisService axisService) throws AxisFault { > ... > AxisService service = null; > AxisService registeredService = > this.axisConfig.getService(this.axisService.getName()); > if (registeredService != null) { > service = registeredService; > } else { > this.axisConfig.addService(this.axisService); > service = this.axisService; > } > > ServiceGroupContext sgc = new ServiceGroupContext(this.configContext, > (AxisServiceGroup) service.getParent()); > this.serviceContext = sgc.getServiceContext(service); > } > ---------------------------------------------------------------- > But this time, there was no addressing and security headers in the soap > message. Then I tried to manually engage the modules as following: > ---------------------------------------------------------------- > stubB._getServiceClient().engageModule(new QName("addressing")); > stubB._getServiceClient().engageModule(new QName("rampart")); > ---------------------------------------------------------------- > It didn't work either. > P.S.: I tried both 1.0 RC5 and 1.0 releases. -- 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
