org.drools.ide_1.0.0.jar ? This seems to be an old version. I would expect to see org.drools.ide_3.0.5 there. But best way to install the JBoss Rules IDE into eclipse is by using the update site and not download the plugin manually, as explained in http://labs.jboss.com/file-access/default/members/jbossrules/freezone/doc.... That will put all the necessary files (including all JBoss Rules jars and their dependencies) in the right location. Notice that you should install GEF before using the update site as the update site will check whether an appropriate version of GEF has been installed before installing JBoss Rules IDE. You only need ant or svn etc. if you want to build from sources. After doing that, you should be able to create a sample project and execute that. If you still keep get errors when compiling the sample HelloWorld project, could you please explain which errors those are exactly?
