[rules-users] KnowledgeAgent and OSGI

[David Conde]

Thanks Mark,

Cheers for the info.

I've seen the OSGi bundle zip (and the boot bundle list [1]) but it seemed
to have quite a large amount of dependencies for just drools-core and
drools-compiler. Do you know if all these bundles are required for this
subset? If not would you happen to have the list of what is?

If you don't have this handy I'll send it on so that you have it once I have
figured it out :)
