The wrapper class is probably running in client space, not server space (at
least thats how my wrapper classes work). If you are in Tomcat/2.1, comp/env
might work. For any other client, though, you would need to look up by jndi
name on the client since comp/env will not be bound.
Only work around would be to get wrapper to run on the server somehow (ie. call
it from another bean instead of client). Otherwise no comp/env for wrapper!
