Could not instantiate Seam component in Tutorial
Hi,
I'm currently doing my first seam project, so therefor I've done a tutorial. This one:
https://docs.jboss.org/tools/2.0.0.GA/seam/en/html/cruddatabaseapplication.html
I've chosen this, because i want to make a small crud application.
So at first here are my installed versions:
Seam: 2.2.2
JBoss: 4.2.3.GA
Eclipse: Helios with Seam Tools 3.2.1, JBossAS Tools 2.2, JBoss WebServices Tools 1.2.1, JBoos Tools RichFaces: 3.2.1 and Hibernate Tools 3.4.0
Java JDK 7
So far the deployment works fine. All java and xhtml files from the database are genereted. As if I'm clicking on http://localhost:8080/RichtModul/UsersList.seam I'm getting following exception:
org.jboss.seam.InstantiationException: Could not instantiate Seam component: usersList at org.jboss.seam.Component.newInstance(Component.java:2170) at

I don't know what causes this error. Is there a problem with seam-gen from the tutorial? Thanks for any help.
