Hi Matthias, Thanks for all the info.
As you said that only one can be defined without a key hence if I use getDataSource(req); then it should use the default datasource without me having to specify the Globals.DATA_SOURCE_KEY as the second parameter. So looking at my struts-config.xml there is only one datasource hence my reading is that the second parameter is redundant. Also Globals.DATA_SOURCE_KEY is showing as deprecated so I was avoiding using it. Looking at it further I see that part of my problem was that I am using JBuilder X which adds a key by default, once that key is added DATA_SOURCE_KEY doesn't work, so obviously the key is the problem. Once I remove the key I can use the single parameter. Thanks for your help!
