What's the actual problem?  When you call findByPrimaryKey, is it
returning nothing, or giving you a stack trace, or what?

I think your primary key class is supposed to have getters and setters
for all the properties, with names matching the primary key fields on
the bean.  So it may be that you need a getChassi and setChassi on the
PK class to get it working.

Thanks,
    Aaron

P.S. Ever played Car Wars?  :)
