If it happens to match your domain or can be customized to do so they can be
great toolkits. If it doesn't they are PITAs ;)

It was years ago, in C++ and came out of academia. Unfortunately it came from
someone who lacked real world experience in the domain. We weren't allowed to
dump it for political reasons ;(

It was a custom toolkit built special purpose for the project. Essentially
just read an xml document into an object model and then used that model to
perform persistence, network distribution, client side caching, replication
etc.
I doubt any specific toolkit could have done what we needed;
* versioned objects that may have "branches"
* may be distributed across multiple servers
* had specific conflict resolution rules when multiple servers synchronized
* icky mapping into relational database
* very particular clientside caching semantics
I guess it would be possible to build a generic toolkit to do this and
annotate using "attributes" and customizable transformers but I have never
had the time to do it ;) You would also need to be able to attach specific
"features" onto each object on model. ie My current project has "actions" and
"querys" associated with each object which is unique to this project.

Not really. I recode the same thing over and over - lots of ugly copy n paste
coding. As each model tends to be relatively domain specific it tends to be
best to do it this way until a generic toolkit is found or built.

I actually can't use Avalon as much as I would like to ;(
Other things I tend to use;
* velocity
* xslt
* sitemesh (on sourceforge)
* xdoclet (on sourceforge) - however I will probably migrate to qdox/vDoclet
if they can offer better stability than xdoclet.
* a customized torque
* struts (though moving away from it now).
* ant
Will eventually use OJB
