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. ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
