TSS runs on Tomcat? Looks like TheServerSide.com runs on Tomcat - or at least that's what their 404 page says. I don't know which is better - TSS's 404, Javablog's 404 (blank page) or JavaLobby's. It's hard to believe that major sites like these don't have better 404 pages.

For those of you who want to add a 404 page to your Java-based webapp, it's as simple as adding the following to your web.xml:

    <error-page>
        <error-code>404</error-code>
        <location>/404.jsp</location>
    </error-page>

Props to InfoQ for implementing a 404 page, even if it is rather useless. Posted in Java at Sep 21 2006, 12:28:22 PM MDT 10 Comments

No one pay us for appropriate Error Messages. That´s the way we walk ;)

TSS is running on JBoss4:)

I think TSS is also running on Tapestry. (at least it used to)

How would you configure an all-encompasing error message? Your example would work fine if someone tried to access http://site/existingContext/foo.jsp but what if they try to access http://site/nonExistingContext?

http://support.microsoft.com/default.aspx?scid=KB;en-us;q218155 dont forget to make your error messages more than 512 bytes else they won't be shown in IE. Arghh!

Good one Sanjiv, I thought I was covered but it looks like Roller has some issues. It looks like it may be fixed in 3.0.

A List Apart (ALA) published an excellent article about "The Perfect 404" months ago, promoting the design of a more "intelligent" 404. I recommend having a read, that's certainly interesting: http://www.alistapart.com/articles/perfect404/
