The id class specified by type does not match the primary key
fields of the class
Hello everybody !
I am faced a migrate project problem. I've got a very very very old java ee
project that currently runs on jboss 4 server. I'm trying to migrate it on a
fresh apache tomee installation.
Entity classes was coded like this:
PK class
Box class
Actually this is works on the jboss 4 server installation but when i'm
trying to start it on apache tomee I got the following error :
I need to keep the @ManyToOne relation inside the PK class. Does someone
know an issue in order to help me ?
Tanks a lot :)

Rick,
Sorry, I failed my copy/paste, this is the whole exception:
In
http://openjpa.markmail.org/thread/bqjomb4mtqj66p2p#query:+page:1+mid:zcxl7qjlqfgv3iwi+state:results
The author said "openjpa.jdbc.SynchronizeMappings=validate did the trick!"
so I tried to change it in my persistence.xml file but without good results
:(
I also read : "The fields of a compound ID class should be one of the
following types : any Java primitive type; any primitive wrapper type;
java.lang.String; java.util.Date;java.sql.Date." That why I tried to change
my entities but same problem.
Thanks for your help

Joe -
First off, the exception that I assume you meant to post isn't showing up?
Second, the patch I posted wasn't for you to modify your Entities. The
important part of that patch is a code fix to the OpenJPA runtime. I
believe this is an OpenJPA code bug and I wanted to get others to take a
look at it. I'll try to bug someone else to review the patch today.
Thanks,
Rick

Hello Rick,
Ty for your answer.
I tried to update my entities like mentionned in your link (Not same
entities inside my first post but same problem):
Entity with embeddedId
Embeddable class
And persistence.xml
But always got this log message:
Are there any solutions to fix it ?

As I mentioned on your SO post, it appears that this problem(or a very
similar one) was reported a (nubmer of times?) long time back[1] but was
never resolved. Attached below is a code fix for trunk along with a unit
test, could I get some additional eyes on this change as I'm not 100%
confident that the change is correct.
Thanks,
Rick
