i have a java class ::

package MyPackage;



import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.sql.Statement;

import java.util.ArrayList;

import java.util.List;

import net.sf.json.JSONObject;



import com.google.gson.Gson;



public class PopulateTextbox {



    Gson gson = new Gson();

    JSONObject obj = new JSONObject();

    JSONArray arr = new JSONArray();

    String temp1;



    String temp;

    List <String>rowValues = new ArrayList<String>();

    List <Integer>rowValues1 = new ArrayList<Integer>();

    String[] contactListNames;

    Connection con=null;

    Statement st=null;

    ResultSet rs=null;





    public String method(){





        try{





        String driver = sun.jdbc.odbc.JdbcOdbcDriver;

        Class.forName(driver);



        String db = jdbc:odbc:Practice_Database;

        con = DriverManager.getConnection(db,,);



        st = con.createStatement();

        String sql = SELECT Emp_Name,ID,Email_Add FROM EmployeeSearch;

        rs = st.executeQuery(sql);



        while(rs.next()){

            obj.put(ID, rs.getInt(ID));

            obj.put(Names,rs.getString(Emp_Name));

            obj.put(Email, rs.getString(Email_Add));

            arr.add(obj);



        }

        //obj.accumulate(ID,rowValues1);



        //obj.accumulate(Names,rowValues);

        temp1 = arr.toString();

        System.out.println(temp1);



   }catch(Exception e){System.out.println(e);}

    /*finally{

        try {

                if(con!=null)con.close();

            } catch (SQLException e) {

        }try {

            if(st!=null)st.close();



        } catch (SQLException e) {



            e.printStackTrace();

        }





    }*/

        return temp1;



    }

    public static void main(String args[])

    {

        PopulateTextbox obj = new PopulateTextbox();

        String temp1= obj.method();





    }

}

This is returning me a Json array. Now i want to call method() of this class in JavaScript again and again to get new values as i update my database. I have a data grid which is working fine as the page loads for the first time with a set of values in this json array. But how to refresh data using Ajax. Or how to call the method() using Ajax so that data gets refreshed when i click on a button on the page. The code where i am calling this method in java-script is ::

<%



    String temp1;

    PopulateTextbox obj = new PopulateTextbox();

    temp1 = obj.method();

    %>

i am getting problem in retrieving new set of values in temp1 through a Ajax call to the server . please help ? Thanks.
