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.

Hi Christian,
personally I don't like this. What happens is that your editors (and developers new to the team) will end up searching the file / jsp in VFS they are seeing in the browser if they want/have to change something. I would not fiddle around with this. However you are free to do it. I'd think of a mod_rewrite in apache. kind regards, Achim Christian Steinert wrote: > 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?

2009/10/18 Christian Steinert <christian_steinert@...> Dear all Not sure if it corrensponds 100% to your request, but I have used URLrewrite to mess with urls. (mainly to remove the /opencms prefix, because I wanted to avoid using Apache httpd in my setup) Read more about here: http://opencms-wiki.org/Removing_the_/opencms/opencms_prefix_without_using_Apache

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.

Dear MichaelHi Christian! For mapping URLs to Resources you can use a Resource init handler. For an example, see org.opencms.main.CmsPermalinkResourceHandler Thank you very much - this looks extremely interesting. For all: in opencms-system.xml, there are several resource handlers that are predefined with the possibility to configure additional handlers. A resource init handler is a class that responsible for mapping a requested URL to a resource in opencms. All handlers are called in sequence, which means that an additional URL scheme can be added without affecting existing functionality. This looks very simple to use and quite elegant. I like this a lot. This is exactly what I was looking for. thanks and regards Christian HTH ------------------- Michael Moossen Alkacon Software GmbH - The OpenCms Experts http://www.alkacon.com - http://www.opencms.org Christian Steinert schrieb: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.
