从java Web服务客户端调用JAX-RPC Web服务的问题

Question

我正在创建一个JAX-RPC Web服务客户端，但是当我调用webservice时，它给了我错误：

  

org.apache.naming.ServiceRef无法强制转换为javax.xml.rpc.Service

客户代码

Context ctx= new InitialContext();
Service service = (Service)ctx.lookup("java:comp/env/service/ROServiceImplService");
QName portQName= new QName("http://services.nic.in","ROServiceImpl");
ROServiceImpl svc = (ROServiceImpl) service.getPort(portQName,ROServiceImpl.class);
String roCode=svc.getROCode(scForm.getEmpCode(),"ashish","6295");

的web.xml
