Hi,

EclipseLink supports Composite Persistent Units. The documentation at http://wiki.eclipse.org/EclipseLink/UserGuide/JPA/Advanced_JPA_Development/Composite_Persistence_Units#Persistence_Unit_Properties_That_Can_Be_Set_on_Composite_Persistence_Units only mentions ways to define children persistent units via jar files.

In practice, we usually use the "composite persistent units" to simplify code. In the same spirit we also care to simplify projects setup, and so we want to avoid having 3 Maven/Gradle/Eclipse projects when only one currently exist.

How can I specify everything in one persistence.xml without creation of extra jar files the rest of my system doesn't need?

Cordially,
Sébastien Tardif
