[jboss-user] [JNDI/Naming/Network] - accessing a database in jboss

[ros060]

Hi,

I have a small application where I access a database using ejb with jsp/servlets. The application is working ok but I have a question about the mysql-ds.xml file and ejb-jar.xml file.

I have pasted the 2 files below. The thing is at the moment I have specified the name of the database in mysql-ds.xml. I would like to state this name in the ejb-jar.xml file so that I do not have to change the name of the database everytime I have to access one.

Shall be thankful if somebody could advise me.
