Help getting up and running with Eclipse Galileo + JBoss Tool for seam project

[chec69]

Hi, after searching everywhere on how to get everything (my development environment up and running ), came here looking for some light
I've been looking for over a week, i have read Manning's Seam in action, witch is a really good book by the way, and i have manage to get seam examples to work, and how mostly it works.
I do not have everything clear yet. I did mimic the examples(without access to Data Base or entities based on database tables), but i did mostly with the "ant deploy" feature that Seam's tutorial suggest, witch is good if you want to get how everything works. Fine There, but i have to get to work, and i feel i have done nothing.
Im using this formula:
eclipse Galileo + Seam 2.2.0GA + JBoss AS 5.1GA + Postgres 8.4

i thought every was going to be fine since i have no problems configuring the JBoos tools in eclipse. but when i made a simple entity bean and made the server up, i thought it was good and that i could continue, but after the server its up, i guess eclipse uploads the .ear file after the server its up in i get this error
