JDBC to RFC Sync Error

Dear All,

I'm creating JDBC to RFC Sync scenario.

Configured according to below link,

http://scn.sap.com/community/pi-and-soa-middleware/blog/2013/12/04/jdbc-to-jdbc-synchronous-scenario-with-rr-beans-and-without-bpm-and-rfc-lookup

Sender JDBC structure is

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

<ns0:MT_JDBC_To_RFC_Source xmlns:ns0="http://FiletoFile.com">

   <row>

      <A>12</A>

      <B>34</B>

   </row>

</ns0:MT_JDBC_To_RFC_Source>

But in Test tab of MM_REQ is showing Red.

Why its showing red?

PFA the attached Screenshot.

Thanks,

Arthita
