<div style="font-family: arial,helvetica,sans-serif; font-size: 10pt;">Hi,<br>
I have an application using drools 3.0.6. I downloaded jboss rules
4.0.2 GA and made necessary changes to the code to make it compatible
to version 4.0.2. When I try to run the application now, I am getting
following error.<br>

I have antlr-runtime-3.0.jar in my classpath which came with drools 4
distribution. I don't have any other version of antlr in my classpath.
Has anyone else encountered this problem? Any help will be appreciated.<br>

That error can only occur if its finding the wrong version of antlr,
maybe you still have the old version in the classpath somewhere?<br>
