I have a simple entity bean which is used to hold serialized objects. It
worked
fine with InstantDB but fails with postgresql. I tried upgrading to
postgresql
7.1.2 from 6.5.3 but that did not fix the problem. I have written a
small bean
to reproduce the problem which is listed below.
Any help or pointers would be much appreciated.
Thanks
Norrie
