seam-gen pulls jboss-seam.jar from its parent directory. So, it should be in the EAR. If it's not, its likely the ant script can't find jboss-seam.jar because you didn't unzip seam-gen.zip into the same folder you extracted "jboss-seam-1.0.1.GA" to. So, a sanity check move would be to make sure that the directory above seam-gen, includes "jboss-seam.jar". Does your directory structure look like this? -jboss-seam-1.0.1.GA -"jboss-seam.jar" and all other files in the root folder for Seam -seam-gen James View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977859#...
