I need to go through many painful manual steps to change the JBPM configuration from H2 to Oracle DB.

This is because persistence.xml and hibernate.cfg.xml is present in many jar files.

Is there any command or simple way to do this as many of the customers are complaining about it becuase whenver they have to setup a new environment the painful manual activites needs to be followed.

May be these configuration files needs to be taken out of jars so that they can be handled easily.

Can someone please help as this is kind of difficult task which makes users reluctant

Thank You in advance.
