Thread: InputStream as parameter not supported

I am using PostgreSQL 7.0, with the jdbc7.0-1.2.jar file.
I am trying to send a Large Object to the database but get an error saying
'InputStream as parameter not supported'
The offending statement is
'stmt.setBinaryStream(1, geomStream, geomStream.available());'
where geomStream is an instanceof ByteArrayInputStream and stmt is a
PreparedStatement.
The exact same code runs beautifully under Oracle, but throws this exeption
under PostgreSQL.
I have followed the documentation to the letter so I don't see why it throws
the exception.
The field in the table is of type 'oid', which the documentation uses.

These methods are implemented in 7.1. Prior to 7.1, you have to use the
getBytes/getBytes methods or the large object api's.
