Thank you Frank and Igor,
this is where wicket differs from a lot of other frameworks and
sometimes its hard to wrap your mind around it: the components are
persistent across requests, they keep their state.
Yes, it is somewhat hard !
In fact, I started from an example I found that used a
Hi all!We're starting a new project that will be quite big (1-2 million users) so now I'm choosing a web framework to use. It seems that Wicket is a very good framework but what worries me is the performance and scalability. I installed wicket-examples on my machine and stress-tested them a bit,

The problem here probably is that outerHTML in explrer doesn't execute

Current svn version should fix this (as well as header contribution), so
please try it and let us know whether it does work.

Hi Johan,

What is ab2 for a thing?It looks like you are 1000 times getting that same bookmarkable page for 100 threads?That page is because of the source code viewer link not stateless so you a creating pages that will go into the sessions.
Now is the question does ab2 work with cookies or not? If not then
Well.. ab2 is an apache benchmarking tool. But I'm under the impression
that it's intended to measure the performance of static pages.
It doesn't use cookies, does it? If I recall correctly there should be a
possibility to specify a cookie value there, so you might be able to
reduce the number
http://httpd.apache.org/docs/2.2/programs/ab.html
I think you're correct with the params, but I've no idea about the cookies.
I think that basic lesson is that the benchmark that was done is only
of use if the OP intended to be serving the Wicket-Examples app out at
that rate - otherwise a more

have you ever seen a struts app? in most struts apps the notion of a

its hard to explain something when
You don't _need_ to know / use OO to program in Java or
C++, but at least they _allow_ you to use OO in your programs. With all
the reading I've done on JSF, I still don't have a clue as to the

It sure seems that sessions are used heavily, but i knew that anyway,
from documentation.
I don't think that sessions are used heavily compared to other
web-apps. The difference is that Wicket does most of the Sessions
tasks for you and it is consistent whereas with Struts etc you end up
doing
the advantage that wicket provides in session handling is that it evicts objects from it for you. what you had to put into a session in lets say a struts app to be accessed across requests you now put into a Page and pass references from page instance to page instance if it is needed across pages.

We have two applications that are largely the same. However, (along
with some minor variations between them) they have completely
different authentication strategies. The call center version
entails logging in once at the start, while the retail version
entails authenticating yourself every time
As long as you separate the business logic (e.g. authentication rules)
from the presentation logic (the HTML), you can use the base language's
object-orientation with most any framework. The real winner for wicket
is the use of object-orientation in the display logic. I think you may

That is probably because - like said elsewhere in this thread - a new

The problem is also that the CPU was on 100%.
