<br> Oh, and BTW, antlr runtimes are not compatible between versions, so, if your netbeans has a different antlr runtime jar in the classpath in a higher priority search order, it will give you similar problems.<br><br>

I only have the one version of antlr jar that comes in the /lib folder of<br>
the drools 5.0 binary distribution, however that was enough to allow me to<br>
run the stockticker fusion sample in eclipse no problem. I ported the<br>
project to Netbeans and am relying on all of the same jars from that binary<br>
distribution, but getting this error now. Perhaps there is something that<br>
is being provided by the eclipse drools plugin?<br>
<br>
Thanks,<br>

Hi,<br>
<br>
in one of my projects, I actually needed two different versions of<br>
antlr in the classpath. Did you check if the class referenced in the<br>
exception actually exists in the deployed antlr jar file?<br>
<br>
Best regards<br>
Marcus<br>
