Yep! Btw Cocoon 2.2 also requires Java 5.
Haven't tested the UUID generator yet, though it seems to be quite
flexible.

+1 for generics

This sounds like a major refactoring task. As said before I'd highly
recommond to focus on having a running Lenya system before doing
any refactoring. The Lenya 2.1 code should run with Cocoon 2.2
without major code changes if configured properly. This includes
Avalon components thanks to Cocoon's avalon-bridge.
Changing code and introducing new API's while migrating
involves the risk of loosing track of the basic migration tasks.
It's also hard to track down any bugs which might be introduced
by the code/API changes and which are not necessarily related
to the migration. Further it's not possible to regression
test any code changes if the system is not functional.
I agree that a lot of dependencies might be unnecessary. But this
should be looked at in a second step after re-establishing a
functional Lenya.

I have the feeling refactoring could be very useful even now. It looks
like a lot of dependencies are actually unnecessary; removing them will
make the bean wiring etc. much easier. For instance, I'd like to remove
the repository handling stuff (o.a.lenya.cms.repository) from the core.
This way, client code that penetrates the publication layer and accesses
the repository directly can be isolated and, hopefully, improved.
But I agree that we should wait with a general refactoring (introducing
generics in the API etc.).

Though I'm all in for generics, I think it's important to focus on
- and it should be our no. 1 goal - having a running Lenya system
again before introducing generics (and changing a whole lot of
method signatures) or doing any other refactoring not
related to the migration.
