This means I have a persistence unit “cms” in my business-components in my cms.jar and this unit is configured via persistence.xml in the including web-application, which uses my “cms.jar”. So every webapplication has its own database and I can reuse my businesslogic for the cms (retrieve content, or images and so on).
