"NullPointerException in JAXWSMetaDataBuilder" To view the discussion, visit: https://community.jboss.org/message/772265#772265 -------------------------------------------------------------- Hi, I'm using jboss 5.1.0 and I'm trying to attach a custom SOAPHandler to a WebService reference injected in an EJB: @Stateless public class MyServiceBean implements MyService { @WebServiceRef(name = "services/MyWebService") private MyWebServicePortType myWebService; } in jboss.xml: <session> <ejb-name>MyServiceBean </ejb-name> <service-ref> <service-ref-name>services/MyWebService</service-ref-name> <service-qname>{ http://mycompany.com/MyWebService http://mycompany.com/MyWebService}MyWebService</service-qname> <handler-chain>jbossws-client-handlers.xml</handler-chain> <wsdl-override> http://myserver/myservice?wsdl http://myserver/myservice?wsdl</wsdl-override> </service-ref> </session> When I call a method on my EJB which uses the WS, I get: java.lang.RuntimeException: Unable to inject jndi dependency: env/services/MyWebService into property com.mycompany.MyServiceBean.myWebService: null at org.jboss.injection.JndiPropertyInjector.lookup(JndiPropertyInjector.java:82) at org.jboss.injection.JndiPropertyInjector.inject(JndiPropertyInjector.java:99) at org.jboss.injection.JndiPropertyInjector.inject(JndiPropertyInjector.java:89) at org.jboss.injection.JndiPropertyInjector.inject(JndiPropertyInjector.java:61) at org.jboss.ejb3.injection.InjectionInvocation.invokeTarget(InjectionInvocation.java:89) at org.jboss.ejb3.injection.InjectionInvocation.invokeNext(InjectionInvocation.java:83) at org.jboss.aspects.currentinvocation.CurrentInvocationInterceptor.invoke(CurrentInvocationInterceptor.java:67) at org.jboss.ejb3.injection.InjectionInvocation.invokeNext(InjectionInvocation.java:74) at org.jboss.ejb3.EJBContainer.injectBeanContext(EJBContainer.java:1086) at org.jboss.ejb3.pool.AbstractPool.create(AbstractPool.java:83) at org.jboss.ejb3.InfinitePool.get(InfinitePool.java:56) at org.jboss.ejb3.InfinitePool.get(InfinitePool.java:51) at org.jboss.ejb3.pool.ThreadlocalPool.create(ThreadlocalPool.java:53) at org.jboss.ejb3.pool.ThreadlocalPool.get(ThreadlocalPool.java:93) at org.jboss.ejb3.stateless.StatelessInstanceInterceptor.invoke(StatelessInstanceInterceptor.java:58) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) at org.jboss.ejb3.tx.NullInterceptor.invoke(NullInterceptor.java:42) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) at org.jboss.aspects.tx.TxPropagationInterceptor.invoke(TxPropagationInterceptor.java:76) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) at org.jboss.ejb3.security.RunAsSecurityInterceptorv2.invoke(RunAsSecurityInterceptorv2.java:94) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) at org.jboss.ejb3.security.RoleBasedAuthorizationInterceptorv2.invoke(RoleBasedAuthorizationInterceptorv2.java:201) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) at org.jboss.ejb3.security.Ejb3AuthenticationInterceptorv2.invoke(Ejb3AuthenticationInterceptorv2.java:186) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) at org.jboss.ejb3.ENCPropagationInterceptor.invoke(ENCPropagationInterceptor.java:41) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) at org.jboss.ejb3.BlockContainerShutdownInterceptor.invoke(BlockContainerShutdownInterceptor.java:67) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) at org.jboss.aspects.currentinvocation.CurrentInvocationInterceptor.invoke(CurrentInvocationInterceptor.java:67) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) at org.jboss.ejb3.session.SessionSpecContainer.invoke(SessionSpecContainer.java:176) at org.jboss.ejb3.session.SessionSpecContainer.invoke(SessionSpecContainer.java:216) at org.jboss.ejb3.proxy.impl.handler.session.SessionProxyInvocationHandlerBase.invoke(SessionProxyInvocationHandlerBase.java:207) at org.jboss.ejb3.proxy.impl.handler.session.SessionProxyInvocationHandlerBase.invoke(SessionProxyInvocationHandlerBase.java:164) ...

To load the handlers-chain file, JAXWSMetaDataBuilder tries to use wsClass.getClassloader().getResource(filename) but the returned classloader is null. The comment on Class.getClassloader() says: "Returns the class loader for the class. Some implementations may use *null* to represent the bootstrap class loader. This method will return null in such implementations if this class was loaded by the bootstrap class loader." That's normal because javax.xml.ws.Service is part of jdk6+. I checked all versions of jbossws-native-cores (up to 4+) and all versions seem to do the same thing. Is there any way to prevent that NPE or is it a bug that can't be avoided?
