Struts 2 provides an easy way to get an object stored in the HTTP session from within the view page. In the example application is HelloWorld.jsp with this markup:

Code Block
XMLhtmlXML
html
titleHelloWorld.jsp Get helloCount Value From HTTP Session

   <p>I've said hello to you <s:property value="#session.helloCount" /> times!</p>

...

Instead of having each action that implements SessionAware also implement the ParameterNameAware interface you can tell the params interceptor to exclude specific request attributes for all actions in a package. In struts.xml configure the struts-default set of interceptors as follows:

Code Block
XMLxmlXML
xml
titlestruts.xml configure params interceptor

	<package name="basicstruts2" extends="struts-default">

 		<interceptors>
	 		<interceptor-stack name="appDefault">
	        	 <interceptor-ref name="defaultStack">
	      			<param name="exception.logEnabled">true</param>
	      			<param name="exception.logLevel">ERROR</param>
	      			<param name="params.excludeParams">dojo\..*,^struts\..*,^session\..*,^request\..*,^application\..*,^servlet(Request|Response)\..*,parameters\...*</param>
	   			</interceptor-ref>
	 	    </interceptor-stack>
		</interceptors>
		
		<default-interceptor-ref name="appDefault" />
