Then create the HelloWorld project, while referencing Drools Runtime as C:/ECLIPSE/PLUGINS That is where the org.drools.eclipse_5.2.1.Final.jar was installed automatically. In the *package explorer*, I could see this jar, and its contents are packages such as * org.drools.eclipse.core * org.drools.eclipse.dsl.editor * org.drools.eclipse.rulebuilder.* But the packages referenced in the sample are unfound and gives resolution problems. Is it possible that the installed package is +fully+ bugged, the helloworld example does not work out of the box ??? Maybe there is a missing package ? Thanks for any hints !!! -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/719675#719675] Start a new discussion in Beginner's Corner at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
