Question

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）注入几个托管Bean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

    (somewhat shortened..)

但是当我直接从UserBean中访问WS时，它可以工作.. 期待您的想法：）

我有解决方案！ Webservices的事务必须是原子的，就像依赖注入一样。但是它试图将请求嵌入到注入事务中（hihi this rhymes），所以它不再是原子的。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();
    }

}
