Hi, I tried to run the drools-example-brms and I got the following error:
RuleAgent(insuranceconfig) INFO (Thu Aug 16 14:40:26 CDT 2007):

The JBoss Business Rules Management System are runing and with the
backup of the rules repository for the example imported.
The path in the brmsdeployedrules.properties for the localCacheDir was
changed to the path in my machine
(///home/.../jbossrules/drools-examples/drools-examples-brms/cache)

Hi Fernano, thank you for your help. I change the classpath but I
still has the problem.
I made a debug and the exeption that is thown is IOException in the
class FileScanner.
The exception says:
java.io.InvalidClassException: org.mvel.CompiledExpression; local
class incompatible: stream classdesc serialVersionUID =
-8459552198577984707, local class serialVersionUID =
-1994048675652702021
The exception was fist catched in URLScaner, loadPackageChanges method
after executing the getCnageSet() method.
I'm running the JBRM in jboss-4.05GA and in the console is displaied
the following:
17:08:50,050 INFO [STDOUT] PackageName: org.acme.insurance
17:08:50,050 INFO [STDOUT] PackageVersion: fmeyer
17:08:50,050 INFO [STDOUT] PackageIsLatest: false
In the console the error looks like the one I send in the last mail.
Regards
Xavier

This is a serialization issue, probably because you are using a
version of mvel in BRMS and another version in your client. check if
they are the same.
