Ok, after a week of tweaking I have my Seam Maven2 projects running in Eclipse on Tomcat6 Embedded Jboss.
I wrote a howto, so I hope this will help others in installing the same configuration. I had to search in many places to get all configuration troubles solved.
No need to create a WAR project from your EAR in this example, so it will certainly speed up your testing process.
The howto is located at my personal site:
Go to architecture, and click on the howto link. it's in PDF format.
Enjoy!
