 try {       
        Connection con = (Connection) DriverManager.getConnection("jdbc:mysql://", "root", "root");

        String query = "select * from state_details"; 
        Statement s = null; 
        s = (Statement) con.createStatement(); 
        ResultSet rs = null;  
        rs = s.executeQuery(query);  
        request.setAttribute("data", rs);  
        RequestDispatcher rd = request.getRequestDispatcher("view.jsp");  
        rd.forward(request, response);  

    } catch (Exception e) {       
    finally {
