Hi marc,
I get the same error: "system is not bound" when I do the lookup using
"system/jdbc/InetSQLServer". Am I missing some configuration item here?
Its almost as if the tomcat stuff can see any of the namespace that jBoss
has set up. Although I am able to at least get a javax.naming.Reference
object when I do a lookup on "InetSQLServer" by itself. Note that I don't
actually get the actual cached datasource object, just the reference class.
Thanks for the help,
Bill Pfeiffer
