Wolfgang suggests using 5.3 or 5.4 as both bring many, many new features and improvements over 4.0.7.
You are also more likely to get help with a newer version (as most people will say "have you tried with 5.3+) if you post problems relating to 4.0.x. The problem you state is caused by not having org.eclipse.jdt.core_3.6.2.v_A76_R36x.jar (or something named similarly, depending on the version of Eclipse you are using, on your classpath). AFAIK this is included with later (i.e. >5.2 onwards) versions of Drools. If you Google for Drools you will easily encounter the Drools Home page and links to download.
