Connection Refused
I'm using slide on my development machine and on a server. The code
runs properly on my development machine, but I get the stack trace
incuded below when I run the code on the server.
I'm accessing an xml file in the slide repository programmatically,
through org.apache.xerces.parsers.DOMParser. My intuition here is that
there's something is going wrong in the xerces code, rather than with
slide, but I'm not sure. "Connection refused" seems to indicate that
slide may be involved.
I print out the url that it's choking on and when I can and past that
url into my browser it loads the file without a problem.
Does anyone have a clue what the problem might be?

Thanks for the suggestion. It turned out to be even more obscure than that.
The hosts file had bad dns info for the slide server domain.

There is also a feature in Xerces to link a local file to the DTD URL.
So the XML file has not to be modified and the network has not to be opened.
Look the documentation of EntityResolver.

Xerces is trying to look up the DTD/Schema (look for the URL in the
first few lines of the XML you are parsing).
It looks like your server machine can't make the connection out to the
internet to get the DTD/Schema.
There are several ways to deal with this: open the network, use a local
URL for the DTD/Schema, don't validate the XML, etc.
This is not a slide bug.
