Hi all,

I'm delving more heavily into JSP/Servlets and JSF at the moment. I've
found something that looks like a questionable design issue by the JEE
folks at Sun (now Oracle, of course) and I'd like to pick your brains
about how you might deal with it.

Basically, when developing a JEE web app, the application name gets
inserted into every URL and associated path. If my app is named
TechDarwinia, for example, then all URLS look like this:

http://localhost:8080/TechDarwinia/
http://localhost:8080/TechDarwinia/faces/readPost.xhtml
http://localhost:8080/TechDarwinia/rsrc/css/style.css

The problem is of course that the web app could be renamed anything by
the deployer/sysop, and I've got strings hard coded to that app name
TechDarwinia.

So how do folks write their apps so that they can handle being deployed
under different names?

<c:url> and equivalent tools that inspect the actual context path (the
"/TechDarwinia/" part of your URL) for the request, largely.
