split Tapestry application into separate modules

I would like to modularize my application into several modules, so that
each one of them would be a separate Maven artifact. I'm trying to
reproduce what I can borrow from tapestry-upload module source, but still
have questions:

- component that was moved into separate module can't be loaded by main
application using standard namespace; is there any way to fix that? (that
is, <t:mycomponent/> results in UknownValueException);
contributeComponentClassResolver() (like in tapestry-upload) doesn't help
(or I just use it incorrectly)

- is that possible to run the whole thing within Eclipse without having to
install 'module' project into local repository?

Thanks in advance.
