JNDI DataSource setup under JDev 10.1.3.2

Question

I have a simple app of a dozen JSP pages, initially delevoped under JDev then deployed (copied, really) to Tomcat. It works fine. I am not using ADF or anything fancy (just JDBC from beans called from the pages). Then I wanted to start using the DBCP pooling that comes standard with Tomcat. This actually worked fine from my adapted pages (now using the jakarta DataSource factory managed by TC). But I have been unable to reproduce the setup in my local development environment, namely JDeveloper 10.1.3.2.
What works so far: I've created a workspace DataSource in the OC4J preferences, added a reference to it in my app's web.xml. Then I can refer to it and use the DS from a simple JSP using JSTL and SQL tags. But my own code cannot seem to be able to retrieve the DS via JNDI using the following snippet:
bq. {color:#000080}Context envContext = (Context) new InitialContext().lookup("java:/comp/env");{color} \\ {color:#000080}return (DataSource) envContext.lookup( dsName );{color}
The exception reported to the client is the following:
bq. {color:#ff0000}java:/comp/env not found \\ {color} \\ (error class: class javax.naming.NameNotFoundException)
All suggestions welcome!
{color:#808080}To the mods: I'd gladly have read the instructions in the sticky
"Please read this before you post" but it won't display correctly. And
I've tried IE6 and SeaMonkey - come on Oracle, you can do better!

Hi!
You probably need to alter your lookup code a bit.
You can do a lookup like this:
    Context envContext = (Context) new InitialContext();
    return (DataSource) envContext.lookup( "jdbc/dsName" );In OC4J, the datasources usually have JNDI names starting with jdbc/ so the lookup to java:/com/env would not return the datasource.
Also, have a look at http://www.oracle.com/technology/sample_code/tech/java/codesnippet/j2ee/jndi/TestConnection.java.txt
