Take a look at line 2 of your drl file.

Apparently it says something like<br>
"import be.comp.permanenties.domain.solver.EmployeeAssignmentTotal"<br>
and then take a look at your java packages and classes<br>
if that exists as a class (and is case sensitive correct).<br>

Out of curiosity, what kind of employee scheduling do you do at the
OCMW?<br>
That would make an interesting, understandable, tangible use case to
blog about it :)<br>
