Weblogic Datasource Configuration

I was trying to configure a datasource on Weblogic for a Webapp using Spring and Hibernate.
And here is the working configuration:

java:comp/env/jdbc/rqc_db-ds is not working.

In this process I have learned two things:
1. Make sure Weblogic talks to the DB via JNDI
2. Make sure the deployed app talks to JNDI 

Note:
rqc_db-ds is just name. Yours could be different.
