Chris,<br>
<br>
There must be a problem with the classpath. That message only
shows up when the antlr-runtime jar is not in the classpath.<br>

java.lang.<o:p></o:p></span></font></p>

<br>
Also, I successfully run examples from command line, outside
of eclipse, so it is unlikely that you are being hit by some hidden dependency.<br>
<br>
Sorry for not helping you more, but continue investigating
your netbeans project classpath for "odd" things.<br>
<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>

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>
