That was failure number one ;-)

Ok, then i would use setBytes/getBytes anyway.

How do i specify that paramter in the URL?

I tried using rs.updateBytes() and using bytea datatype and writing seems to
work now.
But if the data are read back using getBytes() the RTF-Editorkit mourns about
"to many closed brackets", but that might not be a problem of JDBC, still
tracking it down.

Have not yet tried using setBytes() - would that make a difference other than
speed?

Sorry - yes they were contradictory, i just pointed out all ways i tried
already.
