Is there a tool that can generate an apache isis application from JPA classes? Or do I have to rewrite everything with ISIS annotation?

Currently Apache Isis works with JDO, not JPA, so your larger piece of work is to change the JPA annotations. Under the covers we use DataNucleus, which does support JPA, so alternatively you could provide a contribution to enable JPA (this is on our roadmap anyway).

There is no need to add any Isis annotations, but I do anticipate you would need to write additional code in order to expose the business functionality surrounding your core entities. Isis' support for contributed actions and subscribers (over an in-memory event bus) would be a good way to do that.

For further questions, please subscribe to the Isis users mailing list.
