Before I started JBoss 7.1 for first time, I wrote two datasources and drivers in standalone-full.initial.xml and it worked well. The data was written to standalone-full.xml. But since then I am trying to add another datasource but cannot. Whatever I wrote in standalone-full.initial.xml is not getting copied to standalone-full.xml. I tried to write on all files, including standalone-full.xml, standalone-full.boot.xml, standalone-full.latest.xml, but all are getting reverted back to original configuration. I would like to know how to preserve my changes.
