Could anyone help on how to reference system variables(JBOSS AS 7.1) in web.xml ?

i tried the below , where var=NONE defined in system properties in JBOSS server.
<security-constraint>
<web-resource-collection>
<web-resource-name>Secured resources</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<user-data-constraint>
<transport-guarantee>${var}</transport-guarantee>
</user-data-constraint>
</security-constraint>

Internally the JSP pages get converted to Servlets , and the with the help of rresponse objects , content types,..etc. are set.
