configuring auto loading webapps (tomcat 4.0.3)

[Dan Diodati]

Is there a way to 
configure each autoloading webapp without having to add an entry to the 
server.xml?
I know that webapps 
are autoloaded from the webapps directory, the problem is that I need to 
configure a
custom loader for 
each webapp and I don't want to change the server.xml for each new webapp(we 
will have 
lots of them). The 
older tomcat had support to configure different context's in different files, 
which would get added to
the server.xml 
during runtime. With tomcat 4.0.3 they seem to have lost this feature.I 
tried to use the DefaultContext
configuration but it 
does not seem to accept a Loader setting. Anyone know of a way around 
this?

I believe you have to access the HttpServletRequest object(
getContextPath(), etc ). The getServletName() just returns then webapp name
set in the web.xml file.

You can get the name from getServletName, I think the rest of what
you're looking for can be acquired from the servlet context, but
I might be wrong.

Check out the following mehtod from ServletContext:

(cut from javadoc)
getRealPath
public java.lang.String getRealPath(java.lang.String path)Returns a String
containing the real path for a given virtual path. For example, the path
"/index.html" returns the absolute file path on the server's filesystem
would be served by a request for "http://host/contextPath/index.html";, where
contextPath is the context path of this ServletContext..

Howdy,
Thank you for the suggestions.  However, my question is how to do this
in the absence of any requests.  This is for the init() method, so I do
have the servlet context and the servlet config, though.  The context
name is one part, but I need the host, port, etc.

All ideas appreciated,
