JSF HTTP 500 error

Aug 7th, 2008
Hi again (I'm annoying i know, but i just get stuck with things).
I'm using this tutorial: http://www.netbeans.org/kb/61/web/js...ud-wizard.html
I'm using it in combination with mysql+tomcat not java database+classfish.
I have imported the following libraries (after googling what is needed for persistance in tomcat and mysql):
JSF 1.1
JSF 1.2
JTA
JSF 1.1/1.2 Support
MySql JDBC Driver
TopLink Essentials
WebUIComponenets
WebUi Default theme an the usual libraries which is added automatically in netbeans.

I use the automatic generation of the java class files. and my problem is that the main page
where it displays the links is just fine.

Can some please explain what there error mean. I think those are the problems which cause the page not to show stuff.

The source code itself (atleast for one object - property) is as follows:
