How to set the values in session?

Question

If I'm getting empty session I need to setup some values to play the action class. So, here is the method

public SearchFilters getFilters() {
 return (SearchFilters) getSession().get("Filters");
}

I would like to check the session, if it's null, then I need to set the some values over here.

public SearchFilters getFilters() {
if(getSession().get("Filters").equals(null)){
---- //How to set the values and return ?
}
 return (SearchFilters) getSession().get("Filters");
}

So what is the return type of your getSession. are you mean HttpSession? — Niju, Jun 30 '13 at 15:43

getSession() will return a new session if an existing session is not found. So you don't need to worry about this one ever returning null. Take note though, there's no get() method under HttpSession, it's getAttribute().

So you can do this:

public SearchFilters getFilters() {

    if(getSession().getAttribute("Filters") == null) {
         getSession().setAttribute("Filters", new SearchFilters());
    }

    return (SearchFilters) getSession().getAttribute("Filters");
}

If OP is using SessionAware the session is a map, not an HttpSession. OP didn't provide enough details. – Dave Newton Jun 30 '13 at 16:32
Good point Dave, missed that. Anyway the other answer has that covered. Thank you. – Jops Jul 02 '13 at 02:01

Use the code:

public SearchFilters getFilters() {
if(getSession().get("Filters") == null){
  //How to set the values
  getSession().put("Filters", new Filters()); 
}
// and return.
 return (SearchFilters) getSession().get("Filters");
}

assumed you have injected the session into the action via implementing SessionAware.

The value is a free hand object which contains no value, but you could create a constructor to it and pass the value directly.
