i m very new in java so please and please spend ur few movement for this topic.
i want to run a jsp page from within an applet and evantually want to send data to jsp.
the data is an array of string object or may be a properties object,
say String[] strarry={stringdata},or Properties props={setofkeysandvalues}
the url of the jsp is http://8084/UASProject/Registrationform.jsp
i have copied a code snippet from a topic posted in this forum.
now please where should i formate in the code below to achieve this?
    try{
        URL appletURL = getCodeBase();
        String strHost = appletURL.getHost();
        String strPort = String.valueOf(appletURL.getPort());
        String strProtocol = appletURL.getProtocol();
        int portNumber = Integer.parseInt(strPort);
        String strwp ="/UASProject/Registrationform.jsp";
        //TCP port;
        URL jspURL = new URL(strProtocol,strHost,portNumber,strwp);
        URLConnection jspCon = jspURL.openConnection();
        jspCon.setUseCaches(false);
        jspCon.setDoOutput(true);
        jspCon.setDoInput(true);
        //jspCon.set
        ByteArrayOutputStream byteStream = new ByteArrayOutputStream(512);
        PrintWriter out = new PrintWriter(byteStream,true);
       // String postData= "?xmlText=" + URLEncoder.encode(genXml(),"UTF-8");
        //out.print(postData);
        out.flush();
        String strLength = String.valueOf(byteStream);
        jspCon.setRequestProperty("Content-Length",strLength);
        jspCon.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
        byteStream.writeTo(jspCon.getOutputStream());
        URL tempURL = new URL(String.valueOf(jspURL));
        getAppletContext().showDocument(tempURL);
    }catch(Exception e)   {}please explain the line String postData= "?xmlText=" URLEncoder.encode(genXml(),"UTF-8");+ why it is written for??
