current sitemap directory path

Hello

I'm searching to obtain the directory path (absolute or relative to the 
main cocoon directory)
for the currently used sitemap.
I don't find a method.
I've traversed the doc, the sample...without result.

Many samples which seams to use such an information are hard coded and 
become false if there are moved
See, for exemple, the samples:
/samples/modules/realpath.html
/samples/sources/xsp/file
...
and how they works.

I think it is possible to get this information but finding howto is very 
difficult.
Is there a Cocoon gourou which can help me?

As soon as I try to use the resolver like this:
        path = resolver.resolveURI(".");
or
        path = resolver.resolveURI("sitemap.xmap");

I get this error at compile time:
" Error:  line (36) cannot access org.apache.excalibur.source.SourceResolver

                      file 
org\apache\excalibur\source\SourceResolver.class not found"

I have this line in my source
import org.apache.cocoon.environment.SourceResolver;

And I don't find a path in my cocoon tree for org\apache\excalibur\

So I'm unable to use SourceResolver.

I'm having problems with this approach.

I am getting:

Initialization Problem

Message: Could not find component (key [org.apache.excalibur.source.SourceResolver]) (Key='org.apache.excalibur.source.SourceResolver')

Description: org.apache.avalon.framework.service.ServiceException: Could not find component (key [org.apache.excalibur.source.SourceResolver]) (Key='org.apache.excalibur.source.SourceResolver')

Sender: org.apache.cocoon.servlet.CocoonServlet

Source: Cocoon Servlet

cause

org.apache.avalon.framework.context.ContextException: Unable to locate object-model (No environment available)

as soon as I attempt to access any cocoon uri.

I tried instead to pass the service manager to the Source, so it could
fetch the source resolver, and then release it, but this makes no
difference.
I added an implementation for Servicable to my SourceFactory, in order
to get the ServiceManager (so as to get the SourceResolver). Is there
anything else I need to do?

Ok, then you can lookup the SourceResolver in your SourceFactory,
pass the resolver to your Source object, resolve your path
in the Source object and get the absolute path from Source object.

But this is only a solution when a Source object is what you want.
This is not the case for me. I need this information from WITHIN a
Source object, as I need to pass an absolute directory path to a
Berkeley DB XML API.

I tried using context.getRealPath ( request.getSitemapPath () ), but
this does not give the correct answer when the sitemap concerned is
mount from the mount table (and thus is not within the cocoon
build/webapp directory.
So how do I go about it?

You have to use the SourceResolver. Each sitemap component (action,
generator, transformer) gets this object either in the act() method
or in the setup() method.
if you pass a relative path into the SOurcerResolver it's resolved
relative to the current sitemap.
