8:59 a.m.
1- Drools 5.1M2
2- I have logs, but Drools isn't showing any error, everything looks fine,
just changes to files are not used.
3- Agent sees the files because is telling me that has found 4 files, but is
not updating them.
This is my change set file:
<change-set xmlns='http://drools.org/drools-5.0/change-set'
xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'
xs:schemaLocation='http://drools.org/drools-5.0/change-set
drools-change-set-5.0.xsd'>
<add>
<resource
source='file://home/mxhero/workspaceMxHero/engine/configurations/drools/rules/'
type='DRL' />
</add>
</change-set>
In that directory i have 3 rules files. Here is the log by drools:

seconds.
Changes betweens time for update are not reflected.
I know I am probably doing something wrong in the way I am setting the
agent, because i just took the OSGI example and added the agent to it. Any
advice how setting the agent in the right way will be great.
Thanks
