Dan,
Thanks for the help. I did not realize that rule (b) was no
longer in the spec. That helps for "java.lang.Integer".
However, I still am not clear on whether "int" is a valid
PK type. If not, I think it ought to be.
<vendor>
Our product supports either "int" or "Integer" as a PK type,
as well as all other primitive or primitive wrapper types.
</vendor>
It is not clear to me if this is compliant or not with the
EJB 1.1 specification. Should only primitive wrappers be
allowed. And if so, is this sensible, given again that
"int", in Java, means essentially "non-null Integer", which
is a pretty reasonable type for a primary key field.
