Displaytag issue

I am trying to use displaytag for the first time and have an issue with displaytag that I cannot seem to solve. I googled for a solution but couldn't find anything over the internet. Everything else works, it's the only thing that doesn't work.

Basically I'm trying to just do a simple display of the table.

the error I am getting:

org.apache.jasper.JasperException: javax.servlet.ServletException: javax.servlet.jsp.JspException: org.apache.jasper.JasperException: Unable to load class for JSP

      

        
        
        
      

    

JSP page:

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://displaytag.sf.net" prefix="dt" %>

<%--<jsp:useBean id="ForumList" scope="session" class="mysql.Forum" />--%>

<% session.setAttribute( "test2", mysql.Forum.getMyTopics() ); %>

<dt:table name="sessionScope.test2" />

      

        
        
        
      

    

and my class which is really simple

package mysql;

import java.sql.*;
import java.sql.Connection;
import java.lang.*;
import javax.servlet.*;
import javax.servlet.http.*;


import javax.servlet.jsp.jstl.sql.Result;
import javax.servlet.jsp.jstl.sql.ResultSupport;

public class Forum {
    public Connection con = null;
    public Result myTopics = null;
    public MysqlBase mysql = new MysqlBase();


    public Result getMyTopics()
    {
        try
        {
            con = mysql.getConnection();
            Statement stmt = con.createStatement();
            ResultSet result = stmt.executeQuery("Select * from lawers_topics");
            myTopics = ResultSupport.toResult(result);

            con.close();
            stmt.close();
        }
        catch(Exception e)
        {
        }

        //request.setAttribute("MyTopics", this.myTopics);
        return this.myTopics;
    }
}

      

        
        
        
      

    

I would really appreciate if someone can point me in the right direction.

EDIT: I forgot to say that I am using NetBeans and Tomcat6.0 for development.
