[rules-users] Cannot create XmlPullParser

Hey Geoffrey!

I can implement those later if you like, the optaplanner, I'll publish it
at my server and post link later.

Regarding the versions of artifacts in my glassfish, they were all taken
from the drools-planner-5.5.0-Final lib, I even searched for others jars at
glassfish, but I didn't find any.

I'm also on xtream mailing list searching for a solution, I know this is
not regarding drools itself.

One thing I forgot to mention was my project structure, I don't know if
this can be a problem. I have a project called DP where the drool planner
is at, I generate a jar from it and use it at my main web project, I import
it to web-inf/lib. According to java compile rules, theres no problem with
that, since all required libs are there, but I don't know if that can be a
problem for drools compilation to, if there's any particular detail from
drools that would prevent it to work. Basically is this the structure:

-- DP (java project)
-- Web (this uses the DP project)
