[rules-users] Need Camel + drools (OSGI) integration help

[Mark Proctor]

neither spring or camel have been OSGi-ified. only api, core, compiler, 
templates, decision-tables and flow have.

If someone wants to OSGi-ify those and contribute back they are very 
welcome:
1) update the pom.xml to use the osgi bundle plugin, see other existing 
poms.
https://github.com/droolsjbpm/drools/blob/master/drools-decisiontables/pom.xml
2) create an Activator to register the module, again see Activator's for 
core, compiler etc.
https://github.com/droolsjbpm/drools/blob/master/drools-decisiontables/src/main/java/org/drools/osgi/decisiontables/Activator.java
3) update the osgi bundle's pom with new dependencies, make sure to pull 
in the spring ones, unless the actual project provides osgi ready jars.
https://github.com/droolsjbpm/droolsjbpm-build-distribution/tree/master/drools-osgi-bundles
4) Update the boot-bundles.properties so that Spring DM loads the OSGi 
dependencies
https://github.com/droolsjbpm/droolsjbpm-build-distribution/blob/master/drools-osgi-bundles/org.drools.osgi.test/src/test/filtered-resources/boot-bundles.properties
5) write unit tests for spring and camel.
