James,
I'm running Magnolia 3.0RC4 on Tomcat 5.5 - the system's running stable,
so there's no reason to upgrade - although I'm in the process of setting
up a new environment, for which I'll obviously want to use the latest
version.
Anyway, I've set up one, and it works like a charm. I've created a
directory called "error" directly under the context root
("magnoliaAuthor", "magnolia Public", "ROOT", or whatever), and placed a
404.jsp in it.
In the application's web.xml (_NOT_ the web.xml in "tomcat/conf"), I've
added
<error-page>
<error-code>404</error-code>
<location>/error/404.jsp</location>
</error-page>
Restart Tomcat, and hey presto - instant 404! :o)
Your configuration is essentially asking the app server to redirect to
the root "/" on encountering a 404. Since there's no page by default, it
displays the directory listing as the next best thing.
BTW, in a production environment, it is good practice to disable the
directory listing (it's enabled by default). If you're running Tomcat,
go to tomcat/conf/ and open web.xml. Search for
<init-param>
<param-name>listings</param-name>
<param-value>true</param-value>
</init-param>
And change
<param-value>true</param-value>
to
<param-value>false</param-value>
Again, restart Tomcat and you're off.
Hope this helps.
Frank.

Subject: [magnolia-user] 404 handler in Magnolia 3?
This trick no longer works with Magnolia 3:
http://www.magnolia.info/wiki/Wiki.jsp?page=Setup404Handler
It does something though. If I set up web.xml to this:
<error-page>
<error-code>404</error-code>
<location>/</location>
</error-page>
It gives me a directory listing (ooh bad).
If I give it a jsp template like the one at the bottom of this email it
doesn't load. The catalina.log says:
ERROR info.magnolia.context.MgnlContext MgnlContext.java(getInstance:
289) 01.03.2007 17:23:11 MgnlContext is not initialized, This could
happen if the request does not go through magnolia default filters
I noticed an email in the user list archives about filters and 404, but
I have no idea what filters are. Can someone explain how to make a
custom 404 page in Magnolia 3?
