Subject Re: Tomee-plume 7.0.2 context.xml not working as in tomee-plume 1.7.4
Date Sat, 24 Dec 2016 14:45:19 GMT
Hi Romain,
     How do i lookup a datasource instance using JNDI if I deploy it 
using resources.xml ? I am unable to get it using 
java:/comp/env/jdbc/<name>. Can you please let me know the right way of 
doing this?

-Thanks in advance
-SP
