[jboss-user] [JBoss Seam] - seam-gen and hibernate tools! Target Unreachable, identifier

[dashti]

Hi there !

I wanted to generate my entites automatically from my database !

I used jboss-seam-2.0.0.BETA1 , jboss-4.2.1.GA, JBossTools-200706241629-nightly-ALL-win32.

I had 2 ways:

1. I used hibernate tools reverse engineering to do this approach!
I get the lastest dev Jboss IDE from the eclipse update center
and do the tutorial follow the flash , 
http://www.jboss.com/products/seam/captivate/SeamHBTools.swf

there was a big problem that there was no longer @jboss.seam.annotations.IfInvalid in the jboss-seam.jar. and after deleting all references to it, it doesn't work either !

how can I get it work ??!?

2. after that I used Seam Gen:
first of all , I made a new project, and the I used generate entites, it worked properly, but when I run the project, I can login, and after logging in, I go to one of the xyzList pages, and after trying to use Create New row or Search the table, I encounter this exeption:


so now i cannot ran this tutorial , 
maybe this tutorial cannot work in the lastest Jboss IDE or something i do wrong .
