To run the default hello application that comes up as DroolsProject. Yes. You need Eclipse + Jboss Tools + Drools runtime. anonymous wrote : One more question - what is "Drools 5.0 Eclipse 3.4 Workbench"- being used for. That's the plugins in Eclipse for managing / working with a Drools runtime. You can work with Drools independent of Eclipse in the same way that you can use a JBoss AS server w/o the JBoss Tools plugins ... but it's easier w/ an Eclipse-based UI than going commando, er, commandline. :) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4253431#...
