I am using OBJ 0.99 with Oracle 8.1.7.
I am using an RMI client that connect to an RMI server along with a
request in XML (carrying method name and the parameters). This RMI
server uses OJB for persistence.
The problem is like this:
1. Say I added a record, it is saved. While the application (server
side) runs, I can update that record with no problem.
2. With a fresh run of the application (server-side), I can update
1 old record. Any subsequent attempt to update an existing record causes
the following exception. The only way I can run application (client) is
restarting the server application.
Can anyone shed any light?
