I didn't try sem-gen command line. I used all the others tools. For example Jboss IDE Beta, creating a JBoss IDE Project (EAR, WAR and EJB... and adding the libraries and files). I thought Seam was supported... It's very tricky to configure and the environment does not help. I just checked sem-gen command line... ant setup... ant new-project... etc... It's very far from I was looking for.... and seam documentation does not describe to use it as a fundamental thing to configure a project (may be, because It's not very handy to be running ant commands). The key with netbeans is that Seam Plugin uses sem-gen command line as a wizard (very easy to create all the project configuration). In a couple of hours, I migrated all the tests and I'm working with the final project at netbeans.
