JDBC and BLOB in Postgres

Hi,

I'm trying  Blob with JDBC Driver jdbc7.0-1.2  on postgresql 7.0.2.

the setBinaryStream method returns    InputStream as parameter not supported

the getBinaryStream method returns and does nothing.

Does anyone can tell me if the example given in paragraph "Using Large
Objects"  given in Chapter 58. JDBC Interface of the postgres document
is supposed to work ?

Thanks.
