After Session Time out on action user must redirec,

Problem - We need to check if session time is out or server restarted, anyhow session is lost then user must redirected to login page with message “Session Expired. Please Re-login.”
The way I try to resolve above problem is –
I write an custom interceptor where I have some checks to check user session.
I refer that interceptor with defaultStack in some order in a stack and use that stack as default-interceptor-ref. Now my custom interceptor will be called along with default interceptors in an order for each and every action request.
Now till user session persists my application works well but when session timed out it shows me HTTP 400 Bad Request. The Page Can not be found.
Even request dint reach through my custom interceptor. Please tell me where I am doing wrong.
For your reference I am writing some code of struts.xml and my custom interceptor named SessionInterceptor-
<%-- ----------------------------------- Struts.xml ---------------------------------- --%>
<interceptors>
<interceptor name="checkSessionStatus" class="sfa.interceptor.SessionInterceptor" />
<interceptor-stack name="stack1">
<interceptor-ref name="exception"/>
<interceptor-ref name="alias"/>
<interceptor-ref name="servletConfig"/>
<interceptor-ref name="prepare"/>
<interceptor-ref name="i18n"/>
<interceptor-ref name="chain"/>
<interceptor-ref name="debugging"/>

<interceptor-ref name="fileUpload"/>
<interceptor-ref name="checkbox"/>
<interceptor-ref name="staticParams"/>
<interceptor-ref name="conversionError"/>
<interceptor-ref name="validation">
<param name="excludeMethods">input,back,cancel,browse</param>
</interceptor-ref>
<interceptor-ref name="workflow">
<param name="excludeMethods">input,back,cancel,browse</param>
</interceptor-ref>
<interceptor-ref name="checkSessionStatus"/>
</interceptor-stack>
</interceptors>

<result name="Exception" type="tiles">exception</result>
<result name="exception" type="tiles">exception</result>
</global-results>
-------------------------------- struts.xml --------------------------------
------------------------------------ Code of SessionInterceptor is as – ---------------------------
public String intercept(ActionInvocation invocation) throws Exception {
System.out.println("-----------------Start-------------------");
final Object action = invocation.getAction();
final ActionContext context1 = invocation.getInvocationContext();
if (action instanceof ServletRequestAware) {
HttpServletRequest request = (HttpServletRequest) context1.get(HTTP_REQUEST);
((ServletRequestAware) action).setServletRequest(request);
}
if (action instanceof ServletResponseAware) {
HttpServletResponse response = (HttpServletResponse) context1.get(HTTP_RESPONSE);
((ServletResponseAware) action).setServletResponse(response);
}
if (action instanceof ParameterAware) {
((ParameterAware) action).setParameters((Map)context1.getParameters());
}
if (action instanceof ApplicationAware) {
((ApplicationAware) action).setApplication(context1.getApplication());
}
if (action instanceof SessionAware) {
((SessionAware) action).setSession(context1.getSession());
}
if (action instanceof RequestAware) {
((RequestAware) action).setRequest((Map) context1.get("request"));
}
if (action instanceof PrincipalAware) {
HttpServletRequest request = (HttpServletRequest) context1.get(HTTP_REQUEST);
if(request != null) {
((PrincipalAware) action).setPrincipalProxy(new ServletPrincipalProxy(request));
}
}
if (action instanceof ServletContextAware) {
ServletContext servletContext = (ServletContext) context1.get(SERVLET_CONTEXT);
((ServletContextAware) action).setServletContext(servletContext);
}
Map session = invocation.getInvocationContext().getSession();
if(session.get("loginEmp") == null && !((String)(session.get("firstTime"))).equals("Allow")) {
addActionError(invocation, "Session Expires. Please Re- Login");
return "outofsession";
}
session.put("firstTime","");
System.out.println("-----------------End-------------------");
return invocation.invoke();
}
