try this:

<j2ee name="tryout">
   <dbname>MSAccess</dbname>
</j2ee>

The lookup maps to:

java:comp/jdbc/MSAccess

as per the J2EE specs.  If JBoss maps it somewhere else, it is an error.


Unrealated to this, I guarantee you will run into problems developing
against Access and then moving to a real database.  That is a 100%
guaranteed occurance.  I don't care if you are using ColdFusion, Java,
PHP, ASP, JSP, XSP, or whatever.  If you develop against Access thinking
you can move to a real database later you are fooling yourself.

Access requires you to write non-standard SQL statements, and allows you
to use unusual join patterns that won't work on real databases.  Not to
mention when the Access database reaches a certain size, it implodes on
itself.

I have run into Access related problems more than I care to admit.
Therefore I tend to stay away from it.
