That was the problem! I like to keep all jars in one directory; And the jboss-seam.jar was used both under .ear and under web-inf/lib for this reason.
Selectively including the jars (instead of *) needed for the ear inside Ant build.xml does the trick; <zipfileset id="example.war.webinf.lib" prefix="WEB-INF/lib" dir="../../lib/seam"> | <include name="el-api.jar"/> | <include name="el-ri.jar"/> | <include name="jboss-seam-debug.jar"/> | <include name="jboss-seam-ui.jar"/> | <include name="jsf-facelets.jar"/> | </zipfileset> Thanks!
