[jboss-user] [EJB 3.0] - Re: Using enviroment variables in persistence.xml

If you really insist on using an environment variable, then try this (you didn't say which OS you are using, so I'll use Linux syntax). Set the env var: export MYDS="java:MyEJB3DS" then in the run.conf, add: JAVA_OPTS=$JAVA_OPTS -Dmyds=$MYDS and change the persistence.xml file as Jaikiran mentioned. All this does is converts an env var into a system property. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4186748#...
