How to setup your datasource in Wildfly

Below are sample configurations you can use to setup postgresq, mysql data source in your jboss7.x.

Where to add:
1.) If you added Jboss Tools plugin to eclipse, in server view expand Jboss Server->Filesets->Configuration->standalone.xml

2.) Otherwise you can find standalone.xml in JBOSS_HOME/standalone/configuration.
