Disabling Joram in JOnAS 4.8.4

I need to disable Joram (I'm using ActiveMQ instead). Is it sufficient to simply:

* Delete the joram_for_jonas_ra.rar from jonas-base/rars
* Remove the "JOnAS JMS service configuration" properties from jonas-base/conf/jonas.properties
* Remove the JMS-Joram "area" element from jonas-base/conf/jonas_areas.xml

I'm aware there are other Joram related configuration files, for example:

* jonas-base/conf/joramAdmin.xml
* jonas-base/conf/a3debug.cfg
* jonas-base/conf/a3servers.cfg

Is it OK to leave these in place? For example, if I delete joramAdmin.xml and run the "jonas check" command it complains the file cannot be found. I'd also like to delete the JOnAS/lib/commons/jonas/joram directory but again I'm unsure what side effects this may have.

Thanks,

Jonathan.
