J2EE Web服务客户端质量报告(四)_Java教程

客户端服务软件包

　　通过指引WSDL编译器到应用服务器提供的WSDL上可自动生成客户端服务软件包。这个软件包包含许多类。我们需要修改的唯一类就是客户端Stub类。同样地，服务器Web 服务软件包也包含类Tie，它可将Web服务请求绑定到EJB方法上，客户端Stub类为每个服务商业方法的每个客户端配备一个方法。

　　服务Stub类的名称为＜ServiceName＞ServantInterface_Stub，其中＜ServiceName＞就是服务名。我们看看类XactServiceServantInterface_Stub 内的submitWork()方法：

/*
* Implementation of submitWork
*/
public Java.lang.String submitWork(java.lang.String string_1)
throws java.rmi.RemoteException {

　try {
　　StreamingSenderState _state = _start(_handlerChain);
　　 InternalSOAPMessage _request = _state.getRequest();
　　_request.setOperationCode(SubmitWork_OPCODE);
　　Xact.XactServiceServantInterface_SubmitWork_RequestStrUCt
　　_myXactServiceServantInterface_SubmitWork_RequestStruct =new Xact.XactServiceServantInterface_SubmitWork_RequestStruct();
　　_myXactServiceServantInterface_SubmitWork_RequestStruct.setString_1(string_1);

　　SOAPBlockInfo _bodyBlock = new SOAPBlockInfo(ns1_SubmitWork_SubmitWork_QNAME);
　　_bodyBlock.setValue(_myXactServiceServantInterface_SubmitWork_RequestStruct);
　　_bodyBlock.setSerializer(myXactServiceServantInterface_SubmitWork_RequestStruct_SOAPSerializer);
　　_request.setBody(_bodyBlock);

　　_state.getMessageContext().setProperty(HttpClientTransport.HTTP_SOAPACTION_PROPERTY, "");

　　Serializer.attachPendingReportToMessage(_state.getMessageContext());
　　_send((String) _getProperty(ENDPOINT_ADDRESS_PROPERTY), _state);

　　Xact.XactServiceServantInterface_SubmitWork_ResponseStruct
　　_myXactServiceServantInterface_SubmitWork_ResponseStruct = null;
　　Object _responseObj = _state.getResponse().getBody().getValue();
　　if (_responseObj instanceof SOAPDeserializationState) {
　　　_myXactServiceServantInterface_SubmitWork_ResponseStruct =
　　　　(Xact.XactServiceServantInterface_SubmitWork_ResponseStruct)
　　　　((SOAPDeserializationState)_responseObj).getInstance();
　　} else {
　　　_myXactServiceServantInterface_SubmitWork_ResponseStruct =(Xact.XactServiceServantInterface_SubmitWork_ResponseStruct)responseObj;
}

return _myXactServiceServantInterface_SubmitWork_ResponseStruct
.getResult();
} catch (RemoteException e) {
// Let this one through unchanged
throw e;
} catch (JAXRPCException e) {
throw new RemoteException(e.getMessage(), e);
} catch (Exception e) {
if (e instanceof RuntimeException) {
throw (RuntimeException)e;
} else {
throw new RemoteException(e.getMessage(), e);
}
}
}
　　在上述的代码中，我们在_send()之前立即添加了下面的单行：
