JDBC and LOB

Hi, I try to run this example:

String query = "INSERT INTO requestTable VALUES (?,?);";
int i = 1;

PreparedStatement ps =
(PreparedStatement)connection.prepareStatement(query);
ps.setInt(1,i);
ByteArrayInputStream bis = new ByteArrayInputStream(b);
ps.setBinaryStream(2,bis,bis.available());
ps.executeUpdate(); // execute the insert statement
System.out.println("ejecuta");
ps.close(); // close the prepared statement
bis.close();

where de segundo parameter is a oid type.

The response is:

SQL Exception: InputStream as parameter not supported

What tipes of InputStream are supported?
Where can I find more information?

Thanks, Gabi.
