I don't know if this will be useful, but...

I had many problems (some really wierd ones) while my eclipse runtime had Drools 5.0.1 jars.Then I changed it to Drools 5.1.0 jars and everything started to work.
Maybe you should try that!

Hi,
                My Application service(Hilo) is using Jboss Server.
                I have used drools rule engine as part of my Application Process.
                I have compiled it using simple java void main class, it works fine.
                Then i have converted as a simple java process & Deploy as part of
                my application service, i'm getting below error in my stack trace.

                Note:
                1. Drools Version 5.0
                2. Eclipse Version 3.5.0 (IDE which i have used to compile)
                3. I have already tried the solutions suggested in http://www.jboss.org/community/wiki/RulesTomcat
 . Still we are not able to resolve it?

java.lang.NoSuchMethodError:

It will be great, if anybody can help it.


Thanks,
Vadi
