JDBC - setAsciiStream - how to support?

Hello,

I've taken a look at the JDBC driver (from www.retep.org.uk) - tried the jdbc7.1-1.2.jar
and the jdbc7.0-1.1.jar

Both doesn't seem to support the setAsciiStream
jdbc2 PreparedStatement accessor..

I tried using setBytes instead under a transaction block (setAutoCommit(false)), ie..

ps.setBytes(9,this.description.trim().getBytes())

but an error shows up,

FastPath call returned ERROR: lo_write: invalid large obj descriptor (0);

Any ideas?
