Oracle JDeveloper 10g Configuring MySQL DataSources with OC4J and JDeveloper

I'm trying to run through
http://www.oracle.com/technology/products/jdev/tips/duff/mysql_and_oc4j3.html as a first time attempt at installing JDeveloper and working with JNDI and MySQL, but I'm running into problems with this paper.

Firstly, the paper tells me to setup <data-source> entries in the data-sources.xml file (point 2 in the paper); then it tells me to edit the WEB-INF/web.xml to add <resource-ref> items (point 3). Now - I am probably missing something - but where is the link between these two entries... my Java is told to lookup "java:comp/env/jdbc/OraBlogsDS" which it probably finds in the <resource-ref> (web.xml) file but then how does it jump to the <data-source> entries that tell the code how and where to connect to my MySQL database?

Secondly, when I run my (slightly modified) code - I get the following error message when the code attempts the lookup...

code-line : DataSource ds = (DataSource) ctx.lookup("java:comp/env/resource-ref-name-entry");

code-line-error: javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

The Oracle paper fails to tell me about any other requirements such as an application resource file, etc.

Can anyone assist in either of these two points. Many Thanks,
