Can you please write a tutorial on advanced usage of Cayenne? That

ROP docs are there... You can deploy a Hessian ROP service
(essentially a webapp) and use remote clients. Remote client can be a
Swing app, a web app, or any other Java application. Think of it as a
web service vs. a traditional EJB2 service.
We can develop some scenarios, describe them, draw them and prepare
source
templates for people to start with.
Yes, improving the docs and providing more examples is a very good
idea. Any help with this is welcomed. For now we have a 2.0 ROP
tutorial that shows all the moving parts involved. That's a good
start, but I agree that we can go further.
P.S. I am interested in what is _mostly_ accurate, or better yet,
what is
not.
Historically people who ran away from EJB, came to Cayenne or some
other ORM technology. So as it happened, people who do not feel the
need of a physically separate middleware layer running business logic
have always been the majority of the community, and people who used
EJB's were a small minority. This minority used the EJB recommended
approach - DTO, etc. What is not accurate is that _nobody_ used
Cayenne with EJB's.
