Answer : no value for Real Data Source Name, cannot perform jndi

Well, the values would depend upon your WebSphere settings.  I don't know anything about p6spy since I haven't used it.  However, it sounds like you might be able to use information about "application clients", since they allow stand-alone Java applications to access WebSphere resources remotely.  This includes datasources.  So, I suggest that you take a look at this documentation:
