well you need
1- the servlet stuff to see the InitialContext from jboss... something you
need to specify in jndi.properties
2- the db connection under it's "original" container name and not the java:
name (can't remember, have to look at the code naming hookup) jboss puts it
under a name I can't remember for now, can you look at the containerFactory
or something?
java: needs to be hooked up on the client and we need to code that, for now
it is a "bean" thing. This you can work around by 2

|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
