客戶端服務軟件包

　　通過指引WSDL編譯器到應用服務器提供的WSDL上可自動生成客戶端服務軟件包。這個軟件包包含許多類。我們需要修改的唯一類就是客戶端Stub類。同樣地，服務器Web 服務軟件包也包含類Tie，它可將Web服務請求綁定到EJB方法上，客戶端Stub類為每個服務商業方法的每個客戶端配備一個方法。

　　服務Stub類的名稱為＜ServiceName＞ServantInterface_Stub，其中＜ServiceName＞就是服務名。我們看看類XactServiceServantInterface_Stub 內的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().set
　　Serializer.attachPendingReportToMessage(_state.getMessageContext());
　　_send((String) _getProperty(ENDPOINT_ADDRESS_PROPERTY), _state);

　　Xact.XactServiceServantInterface_SubmitWork_ResponseStruct
　　_myXactServiceServantInterface_SubmitWork_ResponseStruct = null;
　　Object _respon SEObj = _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);
}
}
}
　　在上述的代碼中，我們在_send()之前立即添加了下面的單行：
