I found the solution, the mvel in drools-jbrms library is indeed
mvel14-1.2.10.jar, but probably the compilation of the model wasn't done
with that version in the classpath?
Anyway, you need to compile the package org.acme.insurance.base in a
.jar file and upload it as the model in the BRMS ( after you
successfully imported repository_export.xml ) . Than you can deploy the
package in brms and the test units should work fine.

I am having the same problem. Has anyone got this working?
I have tried using mvel version 1.2.8 and 1.2.10 in the classpath of
drools-insurance ( where the jUnit tests are ) and by both the
serialVersionUID is different. So can anyone tell me which version of
mvel is needed to get this working?
Thx,
Waruzjan
