Tomcat 6: How to tell a Context/Webapp where to look for files?

[Steve Mysterious <ti...@gmail.com>]

Hi;

Tomcat:  6.0
Tomcat Installation Directory: C:\Program Files\Apache Software
Foundation\Tomcat 6.0
OS:  Windows XP ( Windows 5.1 service pack 2 )
Java:  JDK  1.6.0_10-beta
Context/Webapp Name:  abcdev

I'm using the above configuration to set up a development environment for
myself.

I used the very convenient and slick installer for Windows that
automatically sets up a service for me with a useful control interface in my
system tray.

My web application is called "abcdev".    I'm setting the "Context" element
for it in a one line file called "abcdev.xml" which I have placed in

c:\Program Files\Apache Software Foundation\Tomcat
6.0\conf\Catalina\localhost\

I noticed that if I don't give my JSPs and my servlet  a path that they look
for files in  CATALINA_HOME aka my installation directory:

C:\Program Files\Apache Software Foundation\Tomcat 6.0

Can I have my JSPs and servlets look for files in other locations without
altering the code?  If so, can I do this on a context (webapp) by context
(webapp) basis?

My apologies if this is in the documentation.  I have read the docs, but I
have been away from tomcat for a few years.  I'm still catching up on a
learning curve.  I'm not used to the jargon yet or the organization of the
docs.

Thanks in advance for any info

Steve

Hi.
Since you apparently just started with this, may I make a recommendation 
that will probably save you a lot of grief later ?
De-install your Tomcat, using the same very convenient installation 
package, and re-install it with the same convenient package, but to a 
directory without spaces in the names, like C:\Tomcat6.
The Service and so on will work just as well, but this will at the very 
least save you a lot of quoting, and at best avoid spending time later 
figuring out why this or that doesn't work as you expect.

You should probably be using ServletContext.getResourceAsStream(), or possibly ClassLoader.getResourceAsStream().  Note that using ServletContext.getRealPath() can be problematic, since the container (Tomcat) is under no obligation to expose the file system (if any) to servlets.
