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.
