The question about having seam to work in war with ejb3 jar file should be for the seam forum (if it really was a ejb3 jar file then you would also need interfaces on tomcat so i assume something else is up) Sounds to me you would like complete freedom over what get packaged - have you tried project archives ? It allows you to define packaging just like you want it. WTP projects does not work with "mixed deployment" projects, project archives does. about the EAR/WAR option in Seam that is used to know which kind of libs you need; and it does create a EAR if you use the Seam project wizard.
