jGuru Structs FAQ

["Thomas E. Burns" <to...@jguru.com>]

Howdy,

We are considering starting a FAQ for Struts on jGuru 
(http://www.jguru.com).  I am curious if anyone on this list is interested 
in managing the FAQ.

jGuru is the most visited site for Java developers and we have very popular 
faqs for servlets, jsp and tomcat already:

http://www.jguru.com/faq/home.jsp?topic=JSP
http://www.jguru.com/faq/home.jsp?topic=Servlets
http://www.jguru.com/faq/home.jsp?topic=Tomcat

We have had a few requests for a Struts FAQ and I think it would be a good 
addition to the site.

Being a FAQ manager on jGuru takes about 1-2hrs/week.  We have created a 
simple interface for the manager to monitor new questions and "promote" 
questions that are appropriate for the FAQ.  The answers can come for the 
community or the FAQ manager.  We would $500/month to the faq manager for 
this FAQ.

You can contact me at tombu@jguru.com if you are interested.

Thanks,

Thomas E. Burns

Re: Refresh button and Back button

[Web Programmer <we...@yahoo.com>]

Basically, the problem is with browsers' caching.  For
example, IE will ignore header settings you sent.  In
several references you will find methods to set
headers, but they all ignore to recognize that it is
after all the browser that decides and/or ignores. 
Back buttons are developers' nightmare.

Refresh button and Back button

[Matt Raible <ma...@yahoo.com>]

I'm sure many of you have run into these problems before:

1.  My form is stored in the session, when the user updates, it goes back to a
list screen, the SaveAction servlet removes the form from the session.
 
PROBLEM:  A NullPointerException is thrown when the user clicks on the "back"
button.

2.  When a user saves a form, they return to the list screen,

PROBLEM:  Another record gets added to the database.

Is there anyway in struts to manipulate the header so the back and refresh
think the last page was the current page?  Can I do this in the SaveAction
servlet?

Please offer any workarounds that you have implemented in your struts
applications.

Thanks,

Matt
