Rainer,
Apparently apache is calling /server-status - I see that mod_status is
enabled in httpd.conf and exercises that context.
One of the frustrations, and I dont know Apache well, is that the
access log seldom updates.
The error log in the same folder does update, but contains little
information--apache restarts is about it.
I don't know if this helps, but I just tried to access the sample web
app from the server machine's own browser
httpd://localhost/sample
and I get "Bad Gateway! The proxy server received an invalid response
from an upstream server
Error 502
locahost
and this does update the access log.

Rainer,
Trying your /sample/ I get the same result.
The log appears to respond to that try but the lines are similar to
those I originally posted from mod_jk.log.
It's as though every context request is translated into '/server-
status'.
Not very likely. Are those entries also appearing in times you are not
testing? If so those are someone else, and your own request isn't
handled by the Apache you are looking at. Can you find your request in
the access log?
Go through all config files and find out, what is configured about
/server-status. That URL doesn't have anything to do with mod_jk.

the bracketed numbers are:

5 maps.

.
[221:268597152] [debug] attempting to map context URI

all the entries are marked [debug].
221 is process httpd with user _www.

You don't have a JkMount for /sample, only one for /sample/*.
What happens, if you point your browser to
http://my.apache.name/sample/
If it doesn't work, extract the lines from your mod_jk log, that
refer
to this request. Look for something like
... [A_NUMBER:ANOTHER_NUMBER] ... Attempting to map URI '/sample/'
from ...
Then note A_NUMBER:ANOTHER_NUMBER which are the process and thread
id
used for the request, and get all lines form the log, which have a
timestamp close to your request and use the same IDs.
Check whether there are any non-debug lines in there. If you can't
see
what goes wrong, post those lines.

what happens instead: the browser tells me: "file not found".
looking at catalina.out it seems the request doesnt reach Tomcat
at all.
How I did it: he quick start guide at
http://tomcat.apache.org/connectors-doc/generic_howto/quick.html
gives a simple proof of concept for a context setup (/examples").
which I have followed implicitly. I believe you have already seen
what I
have done with the config files I posted.
Dennis
P.S as it may be important - if I try example.com:8080/sample the
main
page of my web app loads but all of its subreferences, to gif
images
etc, are broken.

Rainer,
I am not sending /server-status explicitly.
The mod_jk log which I excerpted earlier shows the processing of
server-status before any context is asked for, apparently when
Tomcat
starts up.
The log continues to repeat these entries - apparently mod_jk is
looping
trying to satisfy this context and never does.
No I'm pretty sure this is not the case. I expect someone has a
monitoring tool running or a browser windows with auto-refresh for
/server-status and that's what produces those debug log lines in
mod_jk.
No problem per se.
So back to the basic question: what is your problem? What are you
trying
to achieve, what did you do to make it work, how do you test it,
what
result do you expect and what happens instead?

Rainer
I added JkMountCopy All but this had no effect.

Rainer,
Thanks for the reply. I was confused in my orginal post: I am
not
using
JBoss at all, only mod_jk.
The file contents are as follows below.
Apache has a hosts directory, but I'm not sure if the files
matter.
They
are either the apache .default files or slight modifications of
them,
e.g. virtual_host_global.conf contains just:
Listen *:80
I don't understand, why you test this with a request /server-
status.
That doesn't make sense, because you don't want /server-status
to be
forwarded by mod_jk and in fact you didn't configure it.
So choose a better URL to test (one of the URLs you have a
JkMount
for)
and add "JkMountCopy All".

I am using a mod_jk connector with JBoss.
I am having trouble getting context urls of the form

Any help on how to diagnose what the seeming error is
pointing to
would
be much appreciated.
This log snippet is not useful, because the request you used
was
for
/server-status, which is most likely not a request you want
mod_jk to
send to JBoss.
Please post all your JK directives from your httpd.conf and
the
files
included in that. Also post your workers.properties, and if
you
use it
the uriworkermap.properties file.
The most common cause why simple setups do not work is the
use of
virtual hosts in the Apache configuration. If you have virtual
hosts,
you have to put JkMount into the virtual hosts, or you set
"JkMountCopy
All" in the global part of the configuration.
