session expiration in struts

[lakshmi priya ganapathy]

can anybody say where the session's setMaxInterval() should be given to expire the session in struts.(should it be mentioned in action class)
if not how can i do session expiration using session-timeout in web.xml

It's better to configure the session timeout at web.xml

   <session-config> 
     <session-timeout>600</session-timeout>
   <session-config>

The above entry should take care of setting the session timeout. You don't have to program the timeout. If you want to set in the action class then you can set the timeout in login validation action class.

when i give the coding in web.xml i get the following

Error :The content of element type "web-app" must match "(icon?,display-name?,description?,distributable?,context-param*,filter*,filter-mapping*,listener*,servlet*,servlet-mapping*,session-config?,mime-mapping*,welcome-file-list?,error-page*,taglib*,resource-env-ref*,resource-ref*,security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*,ejb-local-ref*)".web.xmlwebproject/WebContent/WEB-INFline 67

i am developing in Web sphere Studio Application Development.

i have also tried giving setMaxInactiveInterval(3) in the Login jsp page's action class both ways didn't work.can u please suggest some other way.

You need to give the session-config element right after the last servlet-mapping. The exception clearly says the expected order of the elements in the web.xml.
