Need Help and Suggestion

Hi,

In the web application I am working on, each UI has a Cancel button clicking on which should navigate back to the previous page. I cannot use window.history.back() because it does not work when I refresh same page on some action. Example delete on listing.

So, I thought of holding the navigation path in the form of arraylist to the user session so that I will know the complete path from home page to any page.

I have written a two methods that take request and URL to add/remove URL to/from the session. I want all my Action classes to use these methods. I am not sure where I have to place these methods?.in Servlet/Action/POJO?

If Servlet/Action, how can I get the servlet/action object to access these methods?

If POJO will there be any synchronization problem between users?

Ur suggestion will be a great help to me.

Thank you

I have solution to my problem.
I am extending Dispatch Action class and implementing these methods in my base dispatch action class so that these methods are available in all my Action class.

Let me know if u have better solution than this.

Seems like these days I am not getting good anwsers from Javaranch.

Another way to do it is to write a filter. You declare the filter to be executed on all pages by putting it in your web.xml.

This is actually a non-struts specific way, but it feels cleaner. A filter is designed to do one thing and then pass along the request.
