Hi,
 
The WorkingMemory class is inside org.drools package and not inside org.drools.WorkingMemory. Also make sure that you include all the dependency jars. As in my case I also have
- drools-compiler-4.0.4.jar
- drools-jsr94.jar etc

Hi
 
I am new to Drools (using version 4.0.7). I download eclipse workbench and am trying to run the default example in it. But I get the following error
 
java.lang.NoClassDefFoundError: org/drools/WorkingMemory
 
When I looked at the drools-core jar; It seems to be missing WorkingMemory package. What should I do?
 
Using eclipse version 3.4.0.
 
Thanks
Devyani
