Hi again,
this is more of an issue related to the infrastructural setup rather
than a cocoon one.
I cannot think of any standard way of retrieving that bit of information
other than to have it available as a configuration option (e.g. via JNDI).
Since the web application container could be connected to an HTTPD via
AJP or URL rewriting may be used before the request is received by the
application container, or ... there is now way of getting to know, which
url to use as a base for the current servlet.
The only thing, you may want to have look at, is the
javax.servelt.ServletContext. There is a getRealPath() method which may
be what you are looking for in your context.
Cheers,
Thomas

Yes, I need it before a request is made.
Use case is:
I have a worker zipping files (in a cocoon application A). Another
application (B) send a jms message to the worker (A), which files shall
put into a zip file. The zip file is stored into filesystem (A) and
shall be made available for download via http. Application B receives
and acknowledge jms message containing the URI to this zip file. Thus I
need to create the URI for app B withing app A. Getting the host name
isn't a problem, but as app A can be put anywhere in any servlet engine
running on any port I need to figure out this port to be able to create
the URI which is sent back to app B.
In short:
Broadcast a jms message to create a zip file and receive a jms message
containing the (http) URI where the zip file is downloadable.
