Hi everyone,
Thanks for all the help so far. Cayenne is pretty sweet, but I've
got a few more questions/problems. I'm trying to get this thing out the
door and I'm running into the following two problems....
1)
I'm using an Oracle 11g backend, have my sequences all set (with caching
set to 0 in cayenne modeler), and it works fine until my program throws an
exception. Now this exception is being thrown after I'm calling
commitChanges() on the dataContext, but the next time I run my application
it complains about a PK violation and I need to wipe my test DB before
going forward. any ideas?
2)
I'm storing zipped file content in BLOBs... it seemed to be working fine
yesterday, but now I get this (the files today might just be larger, these
files might get pretty big ~1.5GB)....
Exception in thread "Thread-7"

No clue why this is happening other than the fact my byte array is over
4000 bytes, but I'm pretty sure the files from yesterday were too.
Any help is much appreciated. Thanks again.
