I had exactly the same problem when I was evaluating the submissions from last round. Here is a fragment from my .bashrc: export DROOLS_HOME=/home/..../drools-4.0.0.SNAPSHOT-bin.zip_FILES/ export CLASSPATH=$CLASSPATH:$DROOLS_HOME/drools-compiler-4.0.0.SNAPSHOT.jar:$DROOLS_HOME/drools-core-4.0.0.SNAPSHOT.jar:$DROOLS_HOME/lib/antlr-runtime-3.0.jar:$DROOLS_HOME/lib/janino-2.5.7.jar:$DROOLS_HOME/lib/core-3.2.3.v_686_R32x.jar This did not work. As a result I had to run everything from within the Eclipse. MarkA wrote:I've tried that. I copied all the drools jars (14 of them) into a directory and then used that on the classpath - didn't work. I also searched for every jar file on my Mac, put them all in there and tried again - failed. It's only Drools I have a problem with, anything else I create works fine. Manjax23 wrote:Basically the classes you are using are not present in your applications classpath. Put all the drools jar files and the dependent jar files in the class path and run. java -classpath drools.jar;drools-compiler.jar;....;SonsAgesPuzzle.jar <<(optionally classname here)>> Hope this works. Thanks, Manjax23 MarkA wrote:Hi, I downloaded the two examples. If I try to run the jar one I get the classdefnotfound error: java -jar SonsAgesPuzzle.jar Exception in thread "main" java.lang.NoClassDefFoundError: org/drools/WorkingMemory Any ideas? I get this whenever I try to run my own Drools stuff outside eclipse too (works fine inside eclipse) and it is proving a real problem. Obvously it must be possible to create standalone programs that can be run from jar's somehow. Any ideas would be very welcome, Thanks, Mark.

That and find out how to run a drools app outside of eclipse without the noclassdefound error. I'll keep a look out on the list. Mark Proctor wrote:Ellen runs a little "logic club" Dr Gernot Starke one the last one, see mailing list archives for the problem. The winner gets to post the next puzzle, so stay tuned and win, so you can post your puzzle for people to try :) I believe that gernot will post the details of his solution to the blog soon. Mark MarkA wrote:I am a big fan of the logic problem puzzles (the ones with the grids) and would like to play with drools to solve a few - just for a laugh and to see if it can be done. I found a pretty simple one: ---------------------------- Mrs. Robinson's 4th grade class took a field trip to the local zoo. The day was sunny and warm - a perfect day to spend at the zoo. The kids had a great time and the monkeys were voted the class favorite animal. The zoo had four monkeys - two males and two females. It was lunchtime for the monkeys and as the kids watched, each one ate a different fruit in their favorite resting place. Can you determine the name of each monkey, what kind of fruit each monkey ate, and where their favorite resting place was? 1. Sam, who doesn't like bananas, likes sitting on the grass. 2. The monkey who sat on the rock ate the apple. The monkey who ate the pear didn't sit on the tree branch. 3. Anna sat by the stream but she didn't eat the pear. 4. Harriet didn't sit on the tree branch. Mike doesn't like oranges. --------------------- But I can't get the logic working, has anyone done any other examples for drools (or maybe converted the monkey & banana or cannibal ones from CLIPS)? I have looked at the golf one in the examples but it's a bit simple. In that one it uses variables for each bit $bobsColour etc. and then uses those in later rules. I tried it with the one above but I kept needing to refer to a variable that I hadn't yet defined and I couldn't define it as it needed to refer to another one and so on...
