               byte test[]=new byte[input.available()];
               input.read(test);
               input.close();
               * setup OutPutStream
               while(rs.next()){
                                        BLOB blob_locator = (oracle.sql.BLOB)rs.getBlob("Cert");
                    System.out.println("in test:"+);
                    OutputStream outs = blob_locator.getBinaryOutputStream();
                    outs.write(test);
                    outs.flush();
                    outs.close();
but failed ,nothing written into BOLB field.Could you tell me ? thanks
