That's not quite a full explanation. In a javaee app new  
InitialContext() will give you the geronimo jndi tree which has a  
"global" part with stuff like the transaction manager and all your  
datasources bound into it, and also the java:comp component-specific  
javaee tree (which will include the @EJB or xml dd specified ejb refs).

Apparently the ejbs are bound in a different unrelated global jndi  
context.  Personally I consider this a bug.
