Struts2: Accessing Session Variables in JSP's

Struts 2 places named objects including the session onto the OGNL stack. Named objects can easily be retrieves using the s:property tag. For example:

<s:property value="%{#session.User.firstName}"/>

Struts 2 supports other named objects that can be accessed the same way. Suppose the attribute name attrName for all examples below.

Request parameter : #parameters['attrName ']
Request attribute : #request.attrName
Session attribute : #session.attrName
Application Attribute : #application.attrName
