[rules-users] Newbie Trap - Eclipse Install - solved

[Kurt Guenther]

I followed the 5.0

http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-introduction/html/ch03.html#d0e1371

And used the "Create a new Drools 5 runtime....", but I ran into an issue:


org.drools.RuntimeDroolsException: Unable to load dialect

It works fine when I downloaded the 5.0 binaries and just pointed it at 
this.

Plz, let me know if there is a better place to report these issues.   
Also, I found a bunch of documentation nits that I'd like to eventually 
report.
