Hi Max , this is helpful.
RE 1 - yes to both questions. I don't get the error in AS4 and I have both javax and seam on the classpath.
I have (in WEB-INF.lib) all the required jars from the Hibernate 4 download (it didn't work otherwise) as well as the seam jars:
jboss-seam-debug.jar
jboss-seam-excel.jar
jboss-seam-ioc.jar
jboss-seam-mail.jar
jboss-seam-pdf.jar
jboss-seam-remoting.jar
jboss-seam-ui.jar
jboss-seam.jar
Any suggestions?
RE 2 - got it - will ask on the Seam forum.
Thanks,
Dahn
