Title: RE: Bowser back buttons and jsp
I've run into similar problems and decided to deal with it through javascript, hoping the user won't open the page in a new browser window. Although, you can still deal with that problem through javascript.
You get rid of the back button problem by using a javascript link to open the window initially. That way, you can specify whether you want the back button, etc. or not. The following snipit of code will link to your application (or mine) and open a new window, minus the browser functionality.

Subject: Bowser back buttons and jsp
This question doesn't really apply to the webserver in general. I have
developed an ecommerce application using java beans and jsp.
Unfortunately, during qa testing, one problem keeps coming up. If you
click the back button on the browser and ignore the navigation built into
the system, you encounter errors. I've researched if there was a way to
disable the browser navigation options via javascript or some other way but
I found that this is not really possible. What I was wondering is how do
other java professionals handle this problem? Has anyone ever ran into
this?
Re: Bowser back buttons and jsp
I believe you will need to design your system to accomodate this case. There is no workaround that I am aware of, and this is a very common user behavior. tim. > This question doesn't really apply to the webserver in general.

RE: Bowser back buttons and jsp
You can try to get round this on the client side with JavaScript but to do things robustly you need to handle this server side. How do you handle the navigation, validation and processing from your JSP? Have a look at the State pattern, this works really well for an encapsulated approach to this, and can easily be extended to cope with both forward and backward navigation.

RE: Bowser back buttons and jsp
What is an example of the errors? I use a nice freebie menu system, written in JavaScript, for my apps and if the user uses the "Back" button (provided by the browser) and the page has not fully been written by the browser, the browser decides not to display the page at all. If you request to view the source, it's there. Is this the\ kind of error you mean?
