<br> Kris just reminded me of something: do you have the actual Message class in the test program classpath? <br><br> When downloading the package from guvnor, I think it does not download the model jar... only the actual rules, etc...<br>

<br>
Also tried under 5.1.0M1 release.. same issue :(<br>
Am i doing something wrong by declaring the @role in the Configuration<br>
section?<br>
