Setting scope as session can be done with <action > tags in Struts-Config.xml

<action path="/login" name="loginForm" scope="session" parameter="method" type="com.sss.core.LoginAction" input="/index.jsp" /> Source: CoolInterview.com

We have different levels of storage objects(scopes) like

Page
Request
Session
Application
Context like this....we can store the data in any scope like if you want to keep the data in page level u can set the data to page, else you can set to request like this.

we define scope inside action tag in struts.config xml if session is scope than the request processor set data to session scope.but always prefer request scope for good programming. Source: CoolInterview.com
