如何从Web模块向@WebServiceRef注入EJB

我有一个JEE6应用程序，带有一个ejb和一个web模块，在GlassFish 3.1.1上运行现在我想通过将它（作为会话Bean）注入到几个Managed Beans中来访问WebService（JAX-WS）。

@Stateless public class AnyService implements AnyServiceLocal { @WebServiceRef(wsdlLocation = "META-INF/wsdl/AnyService/Any.wsdl") private AnyService service; @Override public String findLastname(Integer key) { Any port = service.getAnyPort(); AnyPerson sp = port.findAnynumber(key); return sp.getLastname(); } } 

当我尝试访问它时：

 @ManagedBean @SessionScoped public class UserBean { @EJB private AnyServiceLocal any; public void findLastname() { name = any.findLastname(Integer.valueOf(key)); } } 

我会得到这些例外

 WARNUNG: A system exception occurred during an invocation on EJB AnyService method public java.lang.String de.mizui.anytest.ejb.bean.AnyService.findLastname(java.lang.Integer) javax.ejb.EJBException at com.sun.ejb.containers.BaseContainer.processSystemException(BaseContainer.java:5193) at com.sun.ejb.containers.BaseContainer.completeNewTx(BaseContainer.java:5091) at com.sun.ejb.containers.BaseContainer.postInvokeTx(BaseContainer.java:4879) at com.sun.ejb.containers.BaseContainer.postInvoke(BaseContainer.java:2039) at com.sun.ejb.containers.BaseContainer.postInvoke(BaseContainer.java:1990) at com.sun.ejb.containers.EJBObjectInvocationHandler.invoke(EJBObjectInvocationHandler.java:213) at com.sun.ejb.containers.EJBObjectInvocationHandlerDelegate.invoke(EJBObjectInvocationHandlerDelegate.java:79) at $Proxy430.findLastname(Unknown Source) ..blabla..

Caused by: java.lang.NullPointerException at com.sun.xml.ws.tx.coordinator.CoordinationManager.lookupOrCreateCoordinator(CoordinationManager.java:175) (somewhat shortened..) 

但是当我直接从UserBean中访问WS时，它可以工作..期待你的想法:)

我有解决方案！ Webservices的事务必须是primefaces的，就像dependency injection一样。 但是它试图将请求嵌入到注入事务中（hihi this rhymes），因此它不再是primefaces的。 您可以使用注释绕过特定方法：

 @Stateless @LocalBean public class AnyServices{ @WebServiceRef(wsdlLocation = "META-INF/wsdl/AnyService/Any.wsdl") private AnyService service; @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED) public String findLastname(Integer key) { Any port = service.getAnyPort(); AnyPerson sp = port.findAnynumber(key); return sp.getLastname(); } }
