Hi,
Q: Is there a way to access/get back exceptions thrown within the
persistance/transaction layer?
Example:
Code (pseudo):
Sateless session bean::SomeEntity someMethod( SomeEntity entity ) {
return this.getEntityManager().merge( entity );
}
Server:
Caused by: org.apache.openjpa.lib.jdbc.ReportingSQLException:
Duplicate entry '0-shortname 1-0000-00-00 00:00:00' for key 2
Client:
Will get SomeEntity with all fields set to null/default.
Well - I would have expected something like 'null' to be returned or an
exception to be thrown, but I have to admit I did not yet fully read the
specs... Nvm I can handle the returned value anyway.
But:
I'd like to give the user a feedback like "... already exists!" which I can do
soley if I get access to the exception thrown on the transaction layer. Is
there something like @TransactionCallback?
Or maybe I went wrong somwhere else?
Thank you in advance.
