[rules-users] Logic Problems & drools

[Ellen Ning Zhao]

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.
