Mihael / Barry,

I'm still struggling to make this work.

So far:
I've tried both scenarios

1) using a table with a bytea column (create table blobs(filename text,
data bytea)) and the latest development driver

2) using a table with a traditional oid column (create table
blobs2(filename text, data oid)) and the latest development driver, and
appending ?compatible=7.1 to the driver URI

In both scenarios uploading text files works perfectly.

ONLY in the second scenario does uploading binary files work. In the
first scenario they return truncated. I am using the BlobTest provided
by Barry.

My database version is 7.1.3 on RedHat 7.2 using Sun Linux JDK 1.3.1.

Where can I go from here? What can I test? I really need to get this
working - so I'm willing to try anything ;) 

Should I bother upgrading the whole DB to 7.2beta to see if it works?


Taking Mihael's advice I've managed to get the binary
