-------------------------------------

    Attachment: DERBY-1471_2.patch
                DERBY-1471_2.stat

I upload patch which modify what was pointed out in mail http://mail-archives.apache.org/mod_mbox/db-derby-dev/200611.mbox/<x7ejrushis.fsf%40Sun.COM>.
 
 * Description of the patch
    * This patch implements Layer B streaming for new methods defined in JDBC4.0 as next.
       * Derby NetClient sends lengthless LOB information in Layer B streaming.
       * Derby NetworkServer receives LOB information sent via Layer B streaming.
 
* Remarkable difference from previous patch
   * Fixed to use lengthless method via EnginePreparedStatement interface.
   * Added message to XJ216.S
   * Supressed length of lines under 80 characters, where possible.

 * Test of the patch
    * Execute derbyall and org.apache.derbyTesting.functionTests.suites.All on jdk16 rc environment
and found no error except for intermittent error of  derbynet/testProperties.java in DerbyNetClient
framework.

> JDBC 4.0 introduced new methods which take parameters for object to be sent to sever
without length information.
> For those methods, Layer B streaming is best way to implement sending object to server.
> This issue is representation of DERBY-1417 in Network Client.
