Before the forward call you should not write anything to the response object. If you
will write anything to response object and then you will forward to some other URL
then you will always get the error.

Gah! The problem is that sendRedirects have to take place before any output
is spooled to the client. It's a HEADER. One would hope your container would
massage the output and cache the body content until it needs to send it down
the line, but apparently it's not doing that.
Thus, the is the pro

Hi All
As far as possible JSP pages should only contain presentation data (html) and not
embedded java code. Programmatical logic should be handled in beans and servlets and
not in jsp pages.
Can someone please be kind enough to tell my why this is important?
Kind Regards

The key word here is role separation and avoiding mess when both programmer

I have three answers:
1. If you have to change common code, you only have to do it in one place:in
the bean or servlet, not in all the pages that excute that code.
2. The JSPs would handle the HTML code and/or JavaScript code making them
more clear.
3. It is possible then, to have a java team wor
Also, we should be able to change the look and feel as much as we want without having
to worry about messing up the functionality of our program. Changing/Editing
presentation layer code should not involve messing with the hard core java
functionality code that is working on the back end.

This can be achieved by including a common jsp.
2 & 3 are more appropriate.

The putValue and getValue methods of the session object have been deprecated

When you do it that way your not storing it as an array, you just storing

The problem would seem to be that the IE6 users are not sending the session
ID through with every request, check by dumping out the seesion id. It
should stay the same for every page for the 5.5 users and differ for every
page for the 6 users (and even accross different requests of the same page).
