I think, it is time to ask a final answer about usage of primitives. In RMI it was
not clear too. I read, I can not use them in remote interfaces with rmiregistry, but
in practice it worked, and other people confirmed it. If it depends on
implementation, let us just talk about JBoss.
1. Can I use primitive arguments and return types in remote interface methods?
2. As persistent fields?
3. As a primary key and its subfields? And what would be an XML tag if yes? Does the
tag <prim-key-type> exist? (it was a recommendation of my EJB course instructor,
perhaps it exists in Orion).
--------------------------------
technically an rmi/iiop type... serializeable class. Long would work... long
wont.

Culprit is <prim-key-type>long</prim-key-type> [the one you have flagged].
Needs to be Java classes I believe.

Subject: [JBoss-user] primitive primary key description
Sorry for not digging into DTDs first. I heard, to make primary key
primitive, one has to change tag <prim-key-class> to <prim-key-type>, but it
does not work. But it does not work. What is a solution?
-------------------------
ejb-jar.xml -----------------------------------------
<cmp-field><field-name>creationTime</field-name></cmp-field>
<primkey-field>creationTime</primkey-field>
<!-- can we have primary key to be a primitive? -->
<prim-key-type>long</prim-key-type>
--------------------------------------server log ---------------------
[Container factory] org.jboss.ejb.DeploymentException: Error in ejb-jar.xml
for Entity Bean OrderEntity: expected one prim-key-class tag
