java - ejb3端点Web服务jboss 7抛出非法状态异常

Question

我有一个这样定义的 Web 服务:

@WebService(endpointInterface = "com.example.Test",
        serviceName = "TestWS")
@Stateless
public class TestWS implements Test {
    public final String basic(final int number) {
        return "{\"Basic\":\"true\",\"number\":" + number + "}";
    }
}

@WebService
@Local
@SOAPBinding(style = SOAPBinding.Style.DOCUMENT)
public interface Test {
    @WebMethod
    public String basic(@WebParam(name = "number")int number);
}

我可以在 [host]/TestWS/TestWS?wsdl 中看到生成的 wsdl，但是当我调用 Web 服务(使用soapui 5.6.2)时，它会抛出非法状态异常:

谁能帮我解决这个问题吗？我尝试遵循 documentation但没有效果。

Answer 1

检查spec ，ch。 3.1“服务实现Bean”(强调我的):

The implementation bean MAY reference a service endpoint interface by using the @WebService.endpointInterface annotation. [...] In this case, the service implementation bean MUST NOT include any JSR-181 annotations other than @WebService and @HandlerChain.

那么您可以尝试从类中的方法中删除@WebMethod注释(接口(interface)方法中的注释应该足够了)<强>并将@SOAPBinding移动到界面？

此外，EJB 方法被标记为final。这可能就是问题所在( ref )。
