Thanks Edson,

I am more like migrating from 3.06 to 4.0. What's the different between 4.0
GA and MR3, and where could I find the download for 40 GA? I couldn't find
any link from the website.


Best Regards,
Tim Nguyen

     If you are upgrading, you should be upgrading to 4.0GA, not MR3.
     The error is because you need to add mvel jar to your classpath.

  Hi,

  I have been using JBoss Drool 3.06 for a few months, and now I want to
  upgrade it to 4.0 to take advantage of some new features. So I downloaded
  the JBoss Rules 4.0.0.MR3 Binaries, then drop 4 core drool jar files to
  my
  project lib
  drools-core.jar
  drools-compiler.jar
  drools-jsr94.jar
  drools-decisiontables.jar

  Then I rebuilt my project, changed a few Drool java code to adapt with
  4.0,
  then Run. I got the following error message:

  java.lang.NoClassDefFoundError:
  org/mvel/intergration/VaribaleResolverFactory.

  Could anyone please let me know if I am mising anything? Thank you!
  PS: My Java drool was working fine with 3.0.6


  Tim
