We're working on the docs and are setup now to provide more and better examples.
HiveMind is very, very new. If it looks polished, that's a compliment ... and
reflects that many of
the ideas in HiveMind gestated inside Tapestry over the last couple of years.
I'm using HiveMind at work ... I think of it largely as a refactoring tool. Case
study #1 is based
on one usage of HiveMind. However, its a proprietary application and completely huge.
A module maps to a jar; you'll have multple packages in the jar but only a single
HiveMind module.
If that's a problem, one solution is to refactor your code into more small modules.
HiveMind really
supports this well, since it (effectively) adds a late binding, where module A defines
the
interface, and module B supplies the implementation.
Due to our current build process, we have a similar issue: multiple logical modules
that are
packaged together as a single JAR. In an ideal world, there would be a
ClassLoader.getTResourceInFolder("/META-INF/hivemind") ... but there isn't. Instead,
we have
"external descriptors", a directory under WebLogic where we store the extra class
loaders; our
servlet's registry bootstrap code processes all the XML files there as well as those
found normally.
It works well, but is not quite ideal for a clustered EAR deployment; we'll want to
graft something
together for that soon. Possibly, our build system will write a catalog of these
external
descriptors into a central file.
