[rules-users] Problems with drools-4.0.7 examples

[Stephen Schaub]

Thanks for the tip, Mark. I did what you suggested, and got the
necessary libraries added to the project build configuration.

I can run the HelloWorldExample, and there are no compile errors for
any of the .java project files. However, there are still lots of
errors reported for the .drl files. When I open the HelloWorld.drl
file and attempt to click the Rete Tree tab at the bottom of the
editor, I get the message:

Rete Tree Build Error!
Reason:
Unable to parse rules to show RETE view!

Am I missing something?
