Re: [rules-dev] Error in drools-example-brms

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.
