Sorry for my bed english :)
Can i develop without jboss AS ?
It is possible to develop seam by chossing Tomcat Project.
Wich configfiles i need for tomcat + hibernate without jeb 3.0 ?
Yes, you can deploy on tomcat with or without ejb3
look at the booking example (using EJB3) or the hibernate example (pretty much the same without EJB3 but with Hibernate).
They both have a deploy.tomcat target for ant which builds a .war deployable in tomcat.
