Hello!

I've been struggling with binding my data to your components and noticed that you got an article on how to use use hibernate with Toolkit components. This feels a bit like overkill but I like to make things the right way and decided to give it a try.. So, I read your article from http://dev/wiki/Articles/UsingHibernateWithToolkit and downloaded Eclipse workspace zip. I imported the project and as I like to enjoy from lightning fast Jetty instead of bulky Tomcat on my development environment I did the following:

1. Added Jetty jars under WebContent/WEB-INF/lib:
jetty-6.1.7.jar, jetty-util-6.1.7.jar and servlet-api-2.5-6.1.7.jar

2. Added Start.java:
Code:
 package com.itmill.toolkit.demo.workoutlog;
 
 import org.mortbay.jetty.Connector;
 import org.mortbay.jetty.Server;
 import org.mortbay.jetty.nio.SelectChannelConnector;
 import org.mortbay.jetty.webapp.WebAppContext;
 
 public class Start {
 
 	public static void main(String[] args) {
 
 		try {
 			final Server server = new Server();
 			final Connector connector = new SelectChannelConnector();
 			connector.setPort(8888);
 			server.setConnectors(new Connector[] { connector });
 			final WebAppContext webappcontext = new WebAppContext();
 			webappcontext.setContextPath("");
 			webappcontext.setWar("WebContent");
 			server.setHandler(webappcontext);
 			server.start();
 		} catch (final Exception e) {
 			e.printStackTrace();
 		}
 
 	}
 
 }


Then I execute Start.java as standard Java application which starts up my Servlet Container but when I load http://localhost:8888/ I do get application loaded to my screen but
1) containers seem to be empty
2) I get following exception when application starts up, what gives?

Code:

Please check Competence Management System from http://dev.itmill.com/svn/incubator/cms/ . It is still work being developed but I know people have tried it out with Jetty too.

I suspect you got some kind of conflict with Jetty classes and Hibernate example classes.
