JBOSS connection pooling

[Mike Blair]

I am trying to get a simple session bean to access my oracle DB. I can't figure out what all needs to be setup for the JBOSS connection pooling. My java code looks as follows:
DataSource dataSource = (DataSource) (new InitialContext()).lookup( "java:comp/env/jdbc/REGENT" );
Connection con = dataSource.getConnection();
Statement stmt = con.createStatement();
I have this wrapped in a try-catch and the error being returned is "JDBC not bound".
I guess my issue is not knowing what all xml files need setup for jndi to work properly. Here is what I think :
add to web.xml
<resource-ref>
<description>Regent Datasource</description>
<res-ref-name>jdbc/REGENT</res-ref-name>
<res-type> javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
add to ejb-jar.xml
<resource-ref>
<res-ref-name>jdbc/REGENT</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
any thing else?
Thanks!
Mike
