Hi Craig
<!ENTITY part1 SYSTEM "part1.xml">
was what I started off with, but it didn't work. Then I tried
<!ENTITY part1 SYSTEM "file:part1.xml">
but no joy. Finally I tried:
<!ENTITY part1 SYSTEM "file:C:\projects\test\WEB-INF\part1.xml">
it worked!
I would really like to use
<!ENTITY part1 SYSTEM "part1.xml">
but I still get the exception File part1.xml not found.
Can you assist further?
Regards
Keith

There is a part of this that is parser-related and part that is Digester
related. See intermixed responses below.

The above URLs assume that your webapp is running in an unpacked directory
that can be accessed with file I/O -- a dubious assumption in many servlet
containers. Try a relative URL like this:
<!ENTITY part1 SYSTEM "part1.xml">
instead. That way, the URL is explicitly recognized as being relative to
the owning document, whatever it's URL is -- and it won't be a file URL if
you do something like this to create the input stream:
InputStream is =
getServletContext().getResourceAsStream("/WEB-INF/struts-config.xml");
This is what Struts does.

Well, this doesn't exactly work because there is no "getAbsolutePath()"
method on the ServletConfig interface. The closest analog would be:
source.setSystemId("file:" + getServletContext().getRealPath("/") + "/"
+ fileName);
However, that still sticks you with using file i/o exclusively -- and this
solution doesn't help you for Struts in any case because it doesn't use
the InputSource option for processing input.
You're much better off using actual relative URLs, as described above.
