1.) the Resource type attribute was wrong. 2.) the ResourceParams factory should be the LdapCtxFactory.
Now what I'm getting back is a null object.
<Resource name="ldap/DirContext" auth="Container" type="com.sun.jndi.ldap.LdapCtx"/>
<ResourceParams name="ldap/DirContext">

When I listBindings on "java:comp/env/ldap" and toString() the object returned, this is what I get back.

I'm hoping to be able to build a Federated Namespace and be able to access my ldap context in a federated fashion from the "java:comp" context for instance "java:comp/env/ldap/ou=foo,o=bar".

If I understand correctly, all the ResourceParams will be handed to the constructor of a LdapDirContext by the above Factory provided by Sun and that I should be able to acquire this context simply with
Context ctx = new InitialContext(); DirContext ldap_ctx = (DirContext) ctx.lookup("java:comp/env/ldap");
However, I consistently get:
Message: Cannot create resource instance
javax.naming.NamingException: Cannot create resource instance

Any help or comment would be greatly appreciated. -Mark
