Looking for standard jndi/jdbc java connection syntax

[bwalker55]

Deploying java servlet code on jBoss for the first time and am having trouble with jndi/jdbc database connection.
Code from long running Tomcat/Resin deployments look like:

Context init = new InitialContext();
 Context ctx = (Context)init.lookup("java:comp/env");
 DataSource ds = (DataSource) ctx.lookup("jdbc/" + dbName); // dbname defined in Tomcat server.xml

With jBoss the above code gives: javax.naming.NameNotFoundException: jdbc not bound error.

As per http://www.jboss.org/community/wiki/WhyDoIGetNameNotFoundException
I have changed the last line to:

DataSource ds = (DataSource) ctx.lookup("java:/" + dbName); // dbname defined in *-ds.xml for jBoss

and this works.

However, I would like to find a solution that works on both servers. I've looked through the JNDI Wiki and FAQ as suggested in the Sticky, but there's nothing obvious jumping out at me as to what I need to do.

Thanks, Bob.
