HI All,
I have three tables tbl_category, tbl_subcategory, tbl_product . where categoryid is foreign key in subcategory table and subcategoryid is foreign key in prduct table. I want to show category and subcategory on home page menubar. I just reach upto display category on menubar but not able to get subcategory on mouseover of particular menu.

So I have a servlet to retrive data and jsp to display it.and jsp code is as below which can show only category.

<ul>
                <% Iterator itr;%>
               <% List data=(List)request.getAttribute("data");
                    for(itr=data.iterator(); itr.hasNext(); ){
                %>
                <li><a href=""><%=itr.next()%></a></li>
                <%}%>
                </ul>



can you please help me to show subcategory on mouseover

     */
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        try {
            Class.forName("com.mysql.jdbc.Driver");
            out.println("<html>");
            out.println("<head>");
            out.println("<title>Servlet Category</title>");            
            out.println("</head>");
            out.println("<body>");
            out.println("<h1>Servlet Category at " + request.getContextPath() + "</h1>");
            out.println("</body>");
            out.println("</html>");
        }catch(ClassNotFoundException cne){
        } finally {            
            out.close();
        }
    }

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)

        response.setContentType("text/html");
        PrintWriter out=response.getWriter();
        ArrayList list=new ArrayList();
        try{
            Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/store?user=shilpa&password=password");
            String query="select category_id,category_name from tbl_category";
            Statement st1=con.createStatement();
            ResultSet rs=st1.executeQuery(query);
            while (rs.next()) {

          rd.forward(request, response);
        processRequest(request, response);
        }catch(Exception e){

        }
    }

    @Override

    @Override
    public String getServletInfo() {

    }// </editor-fold>

Here is jsp code

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@page language="java" import="java.util.*" %>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
             <ul>
                  <% Iterator itr;%>
                  <% List data=(List)request.getAttribute("data");
                     for(itr=data.iterator(); itr.hasNext(); ){
                   %>
                   <li><a href=""><%=itr.next()%></a></li>
              <%}%>
             </ul>

                <%}%>
          </body>
</html>

Which shows result category name from category table only but I want subcategory too on mouseover...
Thank you
