jspInit() sounds better than PostConstruct. UserTransaction can use @Inject
by spec if Im not mistaken so issues are for entity manager and resources.
Here no portable solution but easy to generate at build tume producers for
them. A simpe Mojo/Ant task/gradle plugin would enable it in few lines of
code and in a portable manner.
