namespace not coming in request message-failing in msg map

hi

Sender system is sending

<?xml version="1.0" encoding="UTF-8"?>

<Req>

   <row>

      <A/>

      <B/>

   </row>

</Req>

The message is not giving output in PI message mapping as PI is expecting ns0 and xmlns in the root node and ns0 is closure of root node.

PI is expecting

<?xml version="1.0" encoding="UTF-8"?>

<ns0:Req xmlns:ns0="urn:1.com:2">

   <row>

      <A/>

      <B/>

   </row>

</ns0:HanaReq>

how to handle this situation.. I have jdbc sender..
