The application, session and request objects are available from within
s tags in jsp wherever ognl can be evaluated. Use the #application, #session, or #request syntax to get the object and access values by their keys using ['key'].
Conversely, if you would like to make Struts 2 objects available to a JSP/JSTL scope, the
s:set tag may be used like this:
In Struts 2 OGNL values are automagically exposed to JSP/JSTL; using
<s:set.../> as described above may not be necessary.
A full example below shows a struts variable "jobs" being exposed as "jobz" and being used with jstl and the display tag.
