First, the pkclass attribute has nothing to do with pk generation at
run-time. -This is *build-time*. It's a hint to Middlegen about whether
a Primary Key *class* should be generated for each EJB. Read the docs.
http://boss.bekk.no/boss/middlegen/plugins/cmp20.html#pkclass
As of version 2.0 EJBs generated by Middlegen can (optionally) generate
their own primary key *values* at *run-time*. There are two schemes:
Sequence Block and GUID. These are documented on the same page as above.
-So if any of these are turned on, the generated EJBs will not have pk
arguments, as they will be generated internally in the ejbCreate method.
If you prefer to create your own keys (why would you?), just set
gui="false" and don't use a sequenceblock element.
Also not that if you're on WebLogic, you can take advantage of
WebLogic's proprietary pk generation feature. If you use this and
deploy to WLS, the proprietary pk gen mechanism will be used regardless
of guid and sequenceblock.

It's really hard to tell, since you didn't enclose the relevant part of
the deployment descriptor. It could be Middlegen, XDoclet or JBoss.
Take a look at this page: (no, the content is not offensive)
