[rules-users] Complicated Issue

[abhinay_agarwal]

hey,

M using guvnor 5.3.0 Final version and two instances of guvnor.

In my first guvnor application, i ve two packages containg all my rules
which i am accessing using drools core and knowledge api v5.2.0 Final .I use
type "DRL" to extract rules from my change set.


In my second guvnor application, i just have a package which contains my
JBPM process. Here, i am using drools 5.3.1 Final jars to connect and make
my kbase. i use type = "PKG" in my chnage set, which is contradictory to 
JIRA <https://issues.jboss.org/browse/JBRULES-3388>   is opened that a PKG
cannot be read, but was working fine for my application.

Now i dont want to deploy two different wars of guvnor and was expecting to
do it by deploying just 1 guvnor. 

So instead of taking the headache of using different jars, i used a neutral
GUVNOR and drools 5.4.0 final version. I deployed the guvnor, imported the
old repository, built the packages and tried firing the rules using type =
"DRL" in my change set. Everything Worked fine.

As soon as i changed my type = "PKG" in my change set to access the rules, i
got an error :
