[jira] Resolved: (AXIS2-679) Calling a service from within another
service causes NPE
[ http://issues.apache.org/jira/browse/AXIS2-679?page=all ]
Deepal Jayasinghe resolved AXIS2-679:
-------------------------------------
Resolution: Fixed
fixed in current svn
> 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.
