    Data display using GridPanel from database using Hibernate - Servlet Backend


    Hi,
    I am beginner in Ext JS. I want to display datas from database in gridpanel using Hibernate and Servlet. In many tutorials they explain with PHP. But I want to implement using Servlets and Hibernate FrameWork. Please Help me.

    Do you have a response in JSON or XML coming from your server side code?

    Thanks for your suggestion . I searched for JSON as you told and arrived at the following code. Now its showing an exception as
    'java.lang.ClassCastException: mypack.UserBean cannot be cast to [Ljava.lang.Object;'

    Pls Note : The listOfXrefInfo has the list of users (Checked in debug)

    List<Object[]> listOfXrefInfo;
    listOfXrefInfo = ub.getListOfUsers(); //Getting list of users from database
    JSONObject objResulJson = new JSONObject();
    JSONArray objJSONArray = new JSONArray();
    JSONObject objJsonRow = null;
    Object[] rows=null;

    for (int index = 0; index < size; index++) {

    rows=listOfXrefInfo.get(index);
    objJsonRow = new JSONObject();
    objJsonRow.put("userid", rows[0]);
    objJsonRow.put("username",rows[1]);
    objJsonRow.put("mailid",rows[2]);
    objJsonRow.put("role", rows[3]);


    objJSONArray.put(objJsonRow);
    }
    objResulJson.put("result", objJSONArray);
    objResulJson.put("totalCount", listOfXrefInfo.size());


    out.println(objResulJson);


    Why am i getting this error? Is there any other way out?
