btw you don't need janino if you have jdt core. This is standard java,
there is no reason for this not to work, must be the way you are
setting up your classpath. Btw there is the 4.0.1 SNAPSHOT available
now. Did you rememer to add mvel?<br>

<pre wrap="">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.

<pre wrap="">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.

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,

<pre wrap="">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.

I just want a few more examples to examine really. 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.

<pre wrap="">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...
Many thanks,
Mark.
