It worked fine on my local machine. I added I added ojdbc14.jar under /usr/local/jboss-as/jboss-4.2.3.GA/server/default/lib , but didn't help.
I transferred xxxx-ds.xml file under /usr/local/jboss-as/jboss-4.2.3.GA/server/default/deploy as well.

The web app works when displaying login page, but when it needs to talk to oracle db, it fails.
Any ideas?

thanks,

Are the rights set up correctly on the file?  Doe the user running the JBoss app have access to that file?  It should need only read access.

Are there any firewall concerns between your new environment and the Oracle DB?

Is Oracle configured to allow connections from this machine?

Is the user name password correct?

Do you have the correct connection URL?  Make sure you are not using localhost.
