[rules-users] Deploy Drools in AS7 as OSGi bundles

[Dan Seaver]

I'd like to use Drools as OSGi services in the JBoss Adaptive Server (version
7.1.1).

I haven't found any specifics about how to do this in the drools
documentation (or anywhere else with my google searches), so I'm attempting
to deploy the jars mentioned in the droolsjbpm-integration-docs via the
JBoss Management console. The jars are:

knowledge-api
drools-core
drools-compiler
drools-templates
drools-decisiontables

All of the jars install ok, but when I try to enable them (start the
bundles), I run into problems.
knowledge-api seems to start fine.
However, the other bundles have dependencies on drools-core.
When I try to enable drools-core, I get exceptions claiming the required
bundle, org.drools.internalapi, is missing. So, I added the following
bundle:

knowledge-internal-api.jar

Now I get the exception that package com.google.protobuf is missing.

*Any guidance on how to install drools in AS7 as OSGi services would be
greatly appreciated!*
