[opencms-dev] URL handling

[] Code Create [ Bernd Wolfsegger]

Hi Christian,

Regarding 404 and 500 errors (and if you like some more) have a look here:

http://www.code-create.de/somefilethatdowesnotexist.html

All you need is already there in OpenCms.
Have a look at the /workplace/handler folder.
There you have to customize the handle404.html and handle500.html to your needs.
You can than e.g. use an included structured content and a related jsp (as usual
with structured content) to display fully configurable error pages.
For the 500er you have to change the corresponding entry in the web.xml so that
it looks like the one for the 404.

Hope that helps.

Kind regards, Bernd

Betreff: [opencms-dev] URL handling

Dear all

one of the things that I am unhappy with in opencms is that there is no 
abstraction between URLs and file system resources.

Has anybody in a project implemented some mapping between logical and 
physical URLs? If so, which technique did you use? Servlet filters?

Did anybody successfully implement in a custom 404-handler in opencms? 
Maybe even in a way that works with static export? I am not looking for 
code here, I only try to figure out, how I could create a custom mapping 
of URLs against cms resources, without touching the CMS core and without 
messing around with external things like mod_rewrite.

One thing that would already be a huge improvement is, if resources 
could be addressed like folders, as it is possible in Apache. For 
example, if I have a JSP resource called /foo/bar  and if a request is 
issued for /foo/bar/baz,then it would be incredibly helpful, if actually 
/foo/bar were called. This would very easily allow to create mappers for 
custom url spaces. Does anybody else think this is a good idea? At least 
the request handling and the link management of opencms would be 
affected by this, I think. Also, I don't know how expensive this would 
become, since a naive traversal of the filesystem, whenever a resource 
is not found might cause too much DB activity.

Nonetheless, I wanted to ask, what others think of this.

Kind regards
Christian
