Hi, 
        I modified 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="test.war"   + 
+              domain="test"+
+              parent-first="false"+
+              export-all="NON_EMPTY"+
+              import-all="true">+
+    </classloading>+

 *It helped to solve above mentioned excpetion.And because of this configuration I got rid of the Original Exception also which has been posted in very first post.*
*          Thanks for all..*

       But because of this configuration I got another deployment Exception.I am posting this stack trace too.

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

      I observed that *%JBOSS_HOME% \common\lib\hibernate-entitymanager.jar* is getting conflicting with *WEB-INF\lib\hibernate-entitymanager-3.6.3.Final.jar*

       But how is this possible eventhough I have set *+domain="test"+* .
       Is My observation Correct ?
       Please correct me If I am doing mistake .
