Java Servlet SOAP request

Question

我最近重新学习了Java，所以可能我的代码中有很多愚蠢的错误。我的目标是制作一个向服务器发送SOAP请求的servlet。我使用这个示例来创建SOAP客户机。我将它添加到servlet类中。这显然行不通。你能给我一些技巧来改进这个servlet并理解servlet的逻辑吗?

下面是相关的代码片段:

public class SOAPRequest extends HttpServlet {
    private static final long serialVersionUID = 1L;
    public SOAPRequest() {
        super();
        // TODO Auto-generated constructor stub
    }
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        SOAPConnectionFactory myFct = SOAPConnectionFactory.newInstance();
        SOAPConnection myCon = myFct.createConnection();
        MessageFactory msgFct = MessageFactory.newInstance();
        SOAPMessage msg = msgFct.createMessage();
        SOAPPart mySPart = msg.getSOAPPart();
        SOAPEnvelope myEnvp = mySPart.getEnvelope();
        SOAPBody body = myEnvp.getBody();
        Name bodyName = envelope.createName("GetLastTradePrice", "m", "http://eztrade.com");
        SOAPBodyElement gltp = body.addBodyElement(bodyName);
        Name myContent = envelope.createName("symbol");
        SOAPElement mySymbol = gltp.addChildElement(myContent);
        mySymbol.addTextNode("SUNW");
        message.saveChanges();
        URLEndpoint endPt = new URLEndpoint("http://eztrade.com//quotes");
        SOAPMessage reply = myCon.call(message, endPt);
        myCon.close();
    }

在类路径中是否有所需的jar文件?代码表明您正在使用SAAJ。请获取最新的jar文件，它应该可以工作。
