[rules-users] How to run one example of drools in eclipse?

Fri May 13 03:15:09 EDT 2011

For CR1 we'll have .project and .classpath files in the examples and 
info on how to use it is in its readme.
Try it out:

http://hudson.jboss.org/hudson/view/Drools%20jBPM/job/drools/254/artifact/drools-distribution/target/drools-distribution-5.3.0-SNAPSHOT.zip
Feedback to improve it is welcome here. We're releasing CR1 soon, if the 
feedback is soon, I might be able to process it.
