Hi there.
I'm trying to get OpenJPA running with
Inputstreams. Somehow I always get Exceptions using OpenJPA 1.2.1, Oracle
JDBC driver 10.2.0.4.0 and Oracle Database 10g Enterprise Edition Release
10.2.0.4.0 - 64bit Production.
The entity in question contains one
field maked as:
@Persistent
InputStream data;
This is the exception obtained:
Exception in thread "main"
