Domino中使用Java访问Webservice(二)

   在Lotus Designer开发工具中可以使用Java编写Webservice以及访问Webservice。这里只介绍一下如何访问Websercice。(续)
   其次在Designer中创建一java脚本库，用于连接、发送Soap请求、返回结果的类：WebServiceClient 提供连接方法openWSDLURL，发送Soap请求并返回结果的方法sendSOAPRequest等

public class WebServiceClient {
    private URL wsURL;
    private URLConnection wsURLCon;
    private HttpURLConnection httpUrlConnection;
    private OutputStreamWriter outStream;	//输出流：发送出去
    private InputStreamReader inStream;	//输入流：返回的值
    private BufferedReader bufferedreader;
    Private String sURL,sSoapActionName;
    public void WebServiceClient(){		
    }
    public boolean openWSDLURL(String pURL,String pSoapActionName){
        boolean bool = true;		
        try{
            sURL = pURL;
            sSoapActionName = pSoapActionName;
            wsURL = new URL(sURL);
            wsURLCon = wsURL.openConnection();//打开和URL之间的连接
            httpUrlConnection = (HttpURLConnection)wsURLCon;
        }catch(java.net.MalformedURLException ue){
            bool = false;

        }		
        return bool;
    }
    public String sendSOAPRequest(String pSendXML){
        System.out.println("pSendXML:"+pSendXML);		
        String rXML = "";
        //发送POST请求，需设置使用输入(默认True)输出流；如果是Get请求，直接通过wsURLCon.connect(); 建立实际的连接		
        httpUrlConnection.setDoOutput(true);
        httpUrlConnection.setDoInput(true);
        // Post 请求不能使用缓存 
        httpUrlConnection.setUseCaches(false);
        //设置请求头
        httpUrlConnection.setRequestProperty("Content-Type","text/xml;charset=UTF-8");

        try{
            httpUrlConnection.setRequestMethod("POST");
            httpUrlConnection.connect();
            outStream = new OutputStreamWriter(httpUrlConnection.getOutputStream(),"UTF-8");
            outStream.write(pSendXML);
            outStream.flush();
            outStream.close();
            inStream =new InputStreamReader(httpUrlConnection.getInputStream(),"UTF-8");	
            //程序确定远程响应是字符流，采用字符流读取
            bufferedreader = new BufferedReader(inStream);          
          //此处读取行数据，如果程序无法确定远程响应是字符流，则使用字节流读取即可
            for(String tmpStr = bufferedreader.readLine(); tmpStr != null; tmpStr = bufferedreader.readLine())
                rXML += tmpStr;
            bufferedreader.close();
            inStream.close();
        }catch(java.io.IOException ioe){
            System.out.println("IOE error:"+ ioe.toString());
            ioe.printStackTrace();
        }finally{
            recycle();
        }
        System.out.println("rXML:"+rXML);
        return rXML;
    }	
    private void recycle(){
        try{

            }
