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
