Apache Struts 2 Documentation > Home > FAQs > Cookbook > Application, Session, Request objects in jsp |
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:
<s:set name="jobz" value="jobs" scope="request" /> <c:forEach items="${jobz} var="job"> ... </c:forEach>
"Auto-exposure" 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.
