what entity command for ms sql server 2005

[rcq]

hi everyone

we use jboss 3.2.1, but on the pages for jboss 4, i find several possible entity commands.

what would you use for ms sql server 2005 ?
(my identities are incremented by the database).

I tried already with
<entity-command
name="get-generated-keys" class="org.jboss.ejb.plugins.cmp.jdbc.jdbc3.JDBCGetGeneratedKeysCreateCommand" />

but that doesn't seems to work. (if i do getId in my code, it gives a classcastexception).
