Hi Ales,
       Thanks for your reply.
I read your replies which you did for similar kind of questions.
and because of which only I am able to do this much of configuration .Once again thankful to you.

    Also, I have gone through the your link which you posted here.
    and also , Visited this link :
 *http://phytodata.wordpress.com/2010/10/21/demystifying-the-jboss5-jboss-classloading-xml-file/ http://phytodata.wordpress.com/2010/10/21/demystifying-the-jboss5-jboss-classloading-xml-file/*

    by refering, these links I *removed out jboss-web.xml and jboss-app.xml from war file and updated the jboss-classloading.xml* as follows:

 +<?xml version="1.0" encoding="UTF-8"?>+
+    <!--See  http://phytodata.wordpress.com/2010/10/21/demystifying-the-jboss5-jboss-classloading-xml-file-- http://phytodata.wordpress.com/2010/10/21/demystifying-the-jboss5-jboss-classloading-xml-file-->+
+    <classloading xmlns="urn:jboss:classloading:1.0"+
+              name="emhada.war"   + 
+              domain="emhada.war"+
+              parent-domain="emhada.war"+
+              parent-first="false"+
+              export-all="NON_EMPTY"+
+              import-all="true">+
+    </classloading>+

    i kept domain and parent-domain as same because I wanted to read jars from test.war only.and not from other .war files.

     But by doing this I got following DeploymentException :
