Hey Alon-
I found some good threads regarding your issues. A couple of
interesting points in a nutshell:

1) If you want to use hessian, some have recommended NOT putting the
hibernate.jar on the client. This will effectively perform some of the
scrubbing you want. Supposedly, when hessian deserializes the object,
if it can't find the original collection class, it will revert to using
the default collection equivelant. I guess then that you'd only have to

special handle uninitialized lazily loaded collections; although I'm not

certain they could still be properly handled when returned to the
server.

2) The better option sounds like using Spring's httpinvoker. From what
I understand, it uses normal java serialization methods, of which the
hibernate classes have built in special handling to make everything work

appropriately. Sounds like you'd get deserialized objects on the client

with the same unitialized lazy relationships (which, if accessed, would
properly throw lazyinitializationexceptions.) You still get the http
wire protocol. Only loss would be hessian's ability to service non-java

clients, but it sounds like that's not an issue.

I'm not sure why I wrote all that - better to just show you the threads:

Cool - it all sounds like a lot of fun!
