which version of Jboss server are you using. I believe you need to be on the rc release. Seam has not bee updated to work on the latest version of jboss.

as noted in other threads with the same error:
the seam code generation does not support composite-id's (yet)

as written many times before ;) ....if you really badly want composite-id support then why don't you contribute a patch.

I still get that problem "isJNDIname" not available.
I am trying nightly.

Please help :
JBossIDE-200605041002-nightly-ALL.zip
HibernateTools-3.1.0.200605041002-nightly.zip
and follow the procedure.
and restart with eclipse -clean
