Is this A dumb Question -- How to map table name to bean nam

[gberish]

I am new to J2EE w/jboss.

Where do I map the name of a table in which I want to pesist my bean to the name of the bean?

To date, I always let the container create my Entity Bean's persitance tables and never had to think about it.

But for the first time I need to map a bean to a preexisting table with a funny name, and I just realized I don't know which xml discriptior file to use to map the bean to the funny table name.

Can I do that, or is it like java class names that have to be in file with the same name as the class.

Thanx.

The file you are looking for is called 'jboss.xml', the DTD for this file is in the {jboss.home}/docs/dtd folder of your JBoss installation.

Thanx, but I I couldn't set the table name in jboss.xml and had to use do it in jbosscmp-jdbc.xml.

However, now server keeps looking for its table (members) in the DefaulDS resource (jbossdb database) instead of in the ejbTestDS resource (ejbtestdb database) where I created members.

I can't figue out why.

In case anyone can use what I found so far or is willing to tell me where the server gets pointed to the DefautDs in error, here is my deployment structure.

It is from top (server) to down (my ejb-jar.xml) -- it sure seems to track from the bean to the ejbTestDs resource (ejbtestdb database) to the members table.

Can anyone tell me where it gets lost?
