Hi Chris,
If you want this fixed, please file a JIRA with a reproducible test
case. The message should be useful and it's not. This is a usability
issue that should be fixed. You can even fix it yourself and help
everyone.
Thanks,
Craig

Did you add the Message class to your persistence.xml?
I just love OpenJPA error messages, about as useful as tits on a bull:
"..The configuration property named "openjpa.Id" was not recognized
and will be ignored, although the name
closely matches a valid property called "openjpa.Id" ..."
Looks like the same spelling and capitalisation to me, who the hell
writes these messages? The only useful word in this message is "error"

Subject: Problem build and run hellojpa using Maven
Hi
I have successfully ran the hellojpa sample as described in the
getting
started with Netbeans and Ant.
Now, I'm trying to build and run the same sample using Maven.
When the goal exec:exec is executed, the following ArgumentException
is
thrown:
0 WARN [main] openjpa.Runtime - The configuration property named
"openjpa.Id" was not recognized and will be ignored, although the name
closely matches a valid property called "openjpa.Id".
Exception in thread "main" <openjpa-1.2.2-r422266:898935 nonfatal user
error> org.apache.openjpa.persistence.ArgumentException: Attempt to
cast
instance "hellojpa.mess...@1094d48" to PersistenceCapable failed.
Ensure
that it has been enhanced.

Do you have any idea of what could be the problem?
