Hello, when i try to access datasource in datasource realm from context.xml. I got the datasource name not bound error.

For example, in context.xml under WEB-INF, I have


myDS is the datasource defined in *-ds.xml file in Jboss deployment folder.

My question is, what value I should use for dataSourceName? I tried
"java:/comp/env/myDS", "java:comp/env/defaultDS", "java:myDS". None of them are working.

Plz help
thank you
