Struts 2 after interceptor no data error

I have created a global interceptor which will check for Session timeout.

<interceptors>
                <interceptor class="com.action.SessionChecker" name="sessCheck"> </interceptor>
                </interceptors>

            <default-interceptor-ref name="sessCheck"></default-interceptor-ref>

`

Now it in SessionChecker I check for session timeout

@Override
    public String intercept(ActionInvocation arg0) throws Exception {

        String result;
        Map<String,Object> session = arg0.getInvocationContext().getSession();


          if(session.isEmpty()){

                  result="session_Timeout";

              }
          else
              result=arg0.invoke();

        return result;
    }

Before every request Interceptor is getting called but, then it does not go to action class of that request and though I get corresponding page to the request there is no data.

The following line in your configuration is configuring your session timeout interceptor as the only interceptor in the stack, which is certainly not what you want.

<default-interceptor-ref name="sessCheck"></default-interceptor-ref>

Instead, you need to define a stack that contains all of the interceptors you want to use and define that as your default.

Also, the interceptor you have built is not actually detecting that a session has timed out, but rather just that a session is empty. I'm not sure what is populating your session, but if this interceptor is invoked prior to a new session being properly populated, it will be erroneously identified as timed out.
