服务器Web 服务软件包
服务器Web 服务软件包可自动生成。在Sun ONE Studio中，Web模块的创建只要选择一组EJB Java方法即可，并且Web服务软件包的类可由Web模块创建。
该软件包包含许多类和接口。这里最要害的一个就是＜ServiceName＞ServantInterface_Tie 类，在这个类中服务名就是＜ServiceName＞ 。类Tie是Web服务模块最上面的堆栈；它将引入的服务调用绑定到创建它的EJB组件上。我们只需修改类Tie就可以添加次数纪录。
Tie包括许多方法，但是我们只需修改与EJB商业方法invoke_＜X＞关联的那一个方法。在方法invoke_＜X＞中，＜X＞表示EJB商业方法的名称。我们添加一个 import Payload.*; 到类 Tie上，并对每个商业方法作了一个小小的修改。让我们看看下面的方法 invoke_SubmitWork() ：
/*
* This method does the actual method invocation for operation: SubmitWork
*/
private void invoke_SubmitWork(StreamingHandlerState state) throws Exception {
TransactionService.XactServiceGenServer.
XactServiceServantInterface_SubmitWork_RequestStrUCt
myXactServiceServantInterface_SubmitWork_RequestStruct = null;
Object myXactServiceServantInterface_SubmitWork_RequestStructObj =
state.getRequest().getBody().getValue();
/* Line added to generated method: */
Serializer.queueFirstAttachmentText(state.getMessageContext());
if (myXactServiceServantInterface_SubmitWork_RequestStructObj
instanceof SOAPDeserializationState) {
myXactServiceServantInterface_SubmitWork_RequestStruct =
(TransactionService.XactServiceGenServer.
XactServiceServantInterface_SubmitWork_RequestStruct)
((SOAPDeserializationState)
myXactServiceServantInterface_SubmitWork_RequestStructObj)
.getInstance();
} else {
myXactServiceServantInterface_SubmitWork_RequestStruct =
(TransactionService.XactServiceGenServer.
XactServiceServantInterface_SubmitWork_RequestStruct)
myXactServiceServantInterface_SubmitWork_RequestStructObj;
}
java.lang.String result =
((TransactionService.XactServiceGenServer.XactServiceServantInterface)
getTarget()).SubmitWork
(myXactServiceServantInterface_SubmitWork_RequestStruct.getString_1());
TransactionService.XactServiceGenServer.
XactServiceServantInterface_SubmitWork_ResponseStruct
myXactServiceServantInterface_SubmitWork_ResponseStruct =
new TransactionService.XactServiceGenServer
.XactServiceServantInterface_SubmitWork_ResponseStruct();
SOAPHeaderBlockInfo headerInfo;
myXactServiceServantInterface_SubmitWork_ResponseStruct.setResult(result);
SOAPBlockInfo bodyBlock = new SOAPBlockInfo
(ns1_SubmitWork_SubmitWorkResponse_QNAME);
bodyBlock.setValue(myXactServiceServantInterface_SubmitWork_ResponseStruct);
bodyBlock.setSerializer
(myXactServiceServantInterface_SubmitWork_ResponseStruct_SOAPSerializer);
state.getResponse().setBody(bodyBlock);
}
我们添加了一个单行到invoke_SubmitWork()上：
