Hi,
i use OpenJPA(1.2.1) with OpenEJB(3.1.2).
I know OpenJPA does not support automatic table creation from entities
for SAP MaxDB. So i create the tables manually before using JPA.
Using JPA for reading/manipulating table content works here perfectly
even for SAP MaxDB many times.
But yesterday i had one installation where it doesn't work.
When calling an EJB this installation produces the stack trace at the
end of this email.
Why does the EJB call works normally but not this time?
For another installation, same versions of OpenJPA, OpenEJB, and SAP
MaxDB, everything works fine.
The database product "SAP DB", version "KERNEL 7.6.03 BUILD
015-123-173-107" is not officially supported.
