<br> The broker example is work in progress and requires documentation. <br><br> It is composed of 3 parts. The first step is that you need to use the event generator to create a source data file with the data for the events in the stream. Then you need to use this data file to feed events into the application.<br>

I just installed Drools Fusion (Drools 5.0 CR 1) through the Eclipse Plugin<br>
(thanks Edson). I downloaded the "Drools 5.0.0.CR1 Examples" and am now<br>
trying to run the Broker example (drools-examples-fusion). Starting "Main"<br>
in Eclipse, the "Simple Broker" window opens but the program throws a<br>
java.lang.IllegalArgumentException (see below) with all the $ values in the<br>
graphics window remaining zero.<br>
<br>
I've been stepping through the code but can't seem to find the exact point<br>
the code fails (probably don't have the source for that point). Before I go<br>
any further, I was wondering if anyone else experience this and knows what I<br>
am doing wrong?<br>
<br>
Thanks for the help.<br>
