Normally that means there is something wrong with your .jar, are you
sure there are .class files in there and not .java? We don't compile
.jars we only add them to the classpath.<br>

Hi,
Sorry haven't been on the list for a while, busy with a project, which keeps me now really busy.
We have here an exception which does not seem to make any sense and we're a bit lost in the why and where this happens.
Any help will be appreciated.
Thanks,
Darko IVANCAN
----------------------------------
Steps to reproduce:
1. Log in to jBRMS
2. Created Package as “com.xyz.abcservice.rules”
3. Imported two jars (“rulescore.jar”,” sampleDomain.jar”) into Model.
4. Created New Rule with the following content
package com.xyz.abcservice.rules;
import domain.Accommodation1;
import java.util.List;
import com.xyz.common.rules.api.GenericRuleViolation;
global java.util.List errList;
rule "Conflict Rule 1"
when
accommodation1:Accommodation1(name == "Car")
accommodation2:Accommodation1(name == "Caravan")
then
errList.add(new
GenericRuleViolation(accommodation1,"Invalid cabin combination."));
end
4. Validate it…
------------Output------------------
