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'\].

<s:property value="#application\['foo'\]"/>
<s:property value="#session\['baz'\]"/>

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:
| Code Block |
|---|
| title | Expose OGNL 'jobs' value to JSP/JSTL scope 'jobz' |
|---|
|
<s:set name="jobz" value="jobs" scope="request" />
<c:forEach items="${jobz} var="job">
...
</c:forEach>
|
| Info |
|---|
|
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.
