Hello:
I have constructed a simple (or so I thought) means of outputting a
single item description from an EAD file which takes the XML datastream
of an EAD file and processes it with Saxon via an XSL stylesheet
(another datastream). Ideally it also takes a variable which is the ID
attribute of the item I wish to extract from the EAD file (but I've
given up on that one and hard-wired a value into the stylesheet until I
can get something to work). All of this works outside of Fedora.

Once in Fedora, however, it stops working, no doubt due to my incorrect
use of something somewhere, but how do you debug this? The only obvious
starting point seems to be to re-write the location value of
<http:operation> in the SDep with an example of the URL you are trying
to generate, but even this fails to generate more than an error message
-

javax.ws.rs.WebApplicationException:
org.fcrepo.server.errors.HttpServiceNotFoundException:
[DefaultExternalContentManager] returned an error.  The underlying error
was a org.fcrepo.server.errors.GeneralException  The message was  "Error
getting
http://endure.dur.ac.uk:8080/saxon/SaxonServlet?source=http://endure.dur
.ac.uk:8080/fedora/get/UkDhU:EADCatalogue.0217/EADARCHIVE&style=http://e
ndure.dur.ac.uk:8080/fedora/get/UkDhU:Styles.0005/XSL&clear-stylesheet-c
ache=yes"  

or the variant if you use the .../fedora/objects/... syntax.

The fedora log is no more informative. This CM was based on one that
works, with almost no changes apart from the stylesheet, but it is also
difficult to examine what a working CM does as the log only outputs the
resulting datastream.

Any ideas on a constructive way to investigate this, as trial and error
seems to have failed me?
Thanks for any suggestions.
