Can you point us in the direction where you found this sample project, and also what versions of products you are using? Are you use JBoss Fuse, or something else?
yes, i'm using JBoss Developer studio, where there an option to create a "Sample Drool Project" (under New > Drools Project).
Jboss Fuse 6.0 is the Server
and now it works fine when changed the Drools version from 6.0.0.Final to 6.1.3.Beta3, had wrong version of drool in pom.xml
