Re: PersistenceBrokerException: Error reading class type

[Armin Waibel]

Hi Sven,

sorry, this snip of the stack trace doesn't help much.

Could you please post the whole stack trace. The problem pop up in 
RowReaderDefaultImpl, but the stack trace ends here.
Do you use a field-conversion class for one or more fields of 
de.person.entity.Person?

regads,
Armin

I use OJB PB on a DB2 database and declared the SequenceManagerNativeImpl in
the connection-descriptor. The error pops up once a while. I wonder what
happens here. Any idea?
