Any examples for Postgresql 8.0 using jdbc type 2/3 driver with blobs?

["Brent Friedman" <ledfut(at)gmail(dot)com>]

I made several attempts today to get an example of a blob insert via jdbc
working today, but ran into several errors.  I tried both oid and bytea data
types, and tried the LargeObject manager/methods. [The bytea type probably
won't ultimately work for me - we need to be able to insert blobs of a few
megs each.]   We use 8.0 in production, so newer examples with 8.1/8.2/8.3
specific implementations wouldn't help very much.

So, any ideas where I can find working examples of jdbc/blob operations?

Thanks,
