Hi,
It seems that it works like this. If you access not existing page http://localhost/demo/bla
it's translated in to http://localhost/demo/index/blah. I think that
it's default behavior.

Hi
From my humble point of view, using the activate method to send an
error
when page doesn't exist is not the right place. Imagine that you have
subpackage with there own index page, you will have to duplicate
your code.
But your question is really pertinent, and I had a closer look at the
ComponentEventLinkEncoder service which is used to identify pages
during
request dispatch. And it makes me ask another question :
Why an URL like http://localhost/demo/blah (where demo is the
context) is
translated http://localhost/demo/index/blah where 'blah' become the
activation context of the index even if there there is no activation
method
?
Does it mean that since we have an index page in our application,
404 will
never be thrown automatically ?

Don't think I can help you much, but I can verify the same sendError
and error configurations work for me on Tomcat 5.5 (haven't tried on
Tomcat 6).

Hi All,
I'm playing some time with t5. I have meet simple problem. I hope
that
it's
not my fault.
So.
I would like to handle "Error 404" in my application so I have in
web.xml:
<filter-mapping>
<filter-name>app</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping>
<error-page>
<error-code>404</error-code>
<location>/error404</location>
</error-page>
My Index.java is:
void onActivate(final String pageUrl) throws IOException {
if (isKnownPage(pageUrl)) {
//show page
} else {
response.sendError(404, null);
}
}
If I access page "/hello" then pageUrl property is "hello". If
there is
page /hello then this page is normally processed. If I sendError
then
page
error404 should be shown. This Error page exists. So when I
access /blah
then /error404 page is shown. It works fine with jetty. But it
doesn't
work
with tomcat 6.
I have tried to debug it, and it seems to me, that information about
content
type is lost. In class BufferedGZipOutputStream is already
information
about
content type lost but in class PageResponseRendererImpl is still
present.
thanks for help
Jan
