MR3 was an old milestone release, meaning, it was not feature complete and there were some changes between it and final version. What site were you looking at? Please let us know because we need to take it down... the correct one is this: http://labs.jboss.com/drools/downloads.html []s Edson 2007/8/23, Tim.Nguyen(a)expeditors.com <Tim.Nguyen(a)expeditors.com&gt;: 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.

The error is because you need to add mvel jar to your classpath. []s Edson 2007/8/23, Tim.Nguyen(a)expeditors.com <Tim.Nguyen(a)expeditors.com&gt;: 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 _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users -- Edson Tirelli Software Engineer - JBoss Rules Core Developer Office: +55 11 3529-6000 Mobile: +55 11 9287-5646 JBoss, a division of Red Hat @ www.jboss.com _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users -- Edson Tirelli Software Engineer - JBoss Rules Core Developer Office: +55 11 3529-6000 Mobile: +55 11 9287-5646 JBoss, a division of Red Hat @ www.jboss.com ____________________________________________________________________________________ Be a better Heartthrob.
