Hi All, I'm bit confused with the JNDI bindings and the way they needs to be referred. For example i have a DataSource (I'm using MySQL). In ejb-jar.xml, I bound my datasource as jdbc/MySQL javax.sql.DataSource Container Shareable in jboss.xml, i have the following entry jdbc/MySQL java:comp/env/jdbc/MySQL and there is one mysql-ds.xml copied into deploy folder MySQL ............. Now my question is, how do I refer while looking up for the JNDI bound object, should I be referring as a) lookup("java:MySQL") - taken from mysql-ds.xml b) lookup("java:jdbc/MySQL") - taken from ejb-jar.xml c) lookup("java:comp/env/jdbc/MySQL") - taken from jboss.xml

In WAS6, you use option c. however, in was6 you put this entry in the web.xml through the gui editor and when you save it, was6 binds that info in ibm**bind.xml something file. only then it will work!

When using indirect JNDI lookups, as you are, the URL you use from within you application is "java:comp/env/jdbc/MySQL". The "comp/env/" bit is the namespace reserved for doing indirect JNDI lookups. You could also remove the resource ref configuration from your ejb-jar.xml and jboss.xml and just use "java:/MySQL", that's a direct lookup. In your configuration below, there is a mistake in your jboss.xml, the JNDI name provided there is an indirect lookup, it should be a direct lookup, ie, java:/MySQL
