            </featureManager>


        <variable name="defaultHostName" value="localhost"/>

           <keyStore id="defaultKeyStore" password="mypassword" />

            <!-- Define an Administrator and non-Administrator -->
           <basicRegistry id="basic">
              <user name="admin" password="mypassword"/>
              <user name="nonadmin" password="mypassword"/>
           </basicRegistry>

           <!-- Assign 'admin' to Administrator -->
           <administrator-role>
              <user>admin</user>
           </administrator-role>

</project>

But none of this option is working.Server is not loading these jar's due to this Spring application context is not getting loaded.But same application is working fine if I package all the jar's in WEB-INF/lib folder.
