It should be the primary key class. There is really no difference to any
other user defined primary key class.
I've done this with String and int and have had no problems.
To make life a bit easier, I sometimes define an extra finder method
findById() that takes the primitive type as an argument.

For portability I currently do not use primitive primary keys at all.
But I hope this will change...

Strange, I've had no problems with this.
Are you sure you remembered to change the primary key everywhere
(home.findByPrimaryKey(), bean.ejbFindByPrimaryKey() return type,
ejb-jar.xml, etc.) ?
