If you want to stay with 2.7, you should recompile Xerces with the
libwww NetAccessor; then in your code use the libwww API for registering
a proxy (I think it is HTProxy_add) and at that point I think you should
be able to load URLs.

Do I need to recompile Xerces to support netaccessor and does this require
upgrading Xerces from 2.7.0 to 3.0.1?
I have confirmed that my entity resolver is being called. Now, is there away in
Xerces to specify the proxy and port like
proxyHost="use-this-proxy" and proxyPort="use-port"? I would rather use Xerces
to handle the entity resolution if at all possible.
Thanks for your assistance

Dantlzer,
you are providing your own entity resolver, so Xerces will call you to fetch
the external entity; try adding a few debugging traces to verify that you are
indeed called and that you are able to resolve the given URL.
In any case, as you are behind a proxy, you should manually retrieve the entity
(using whatever feature your platform provides - WinHTTP for Windows, cUrl for
Unix..) and wrap it in a MemBufInputSource object.

HI Alberto
I ran across a reference(link below) given by you a few years ago on a similar
problem which I think is related to mine.
http://marc.info/?l=xerces-c-users&m=118373267604850&w=2
I forgot to mention that I'm also behind a firewall and need to access our
company's proxy. I don't know if a NetAccessor was compiled in our version of
Xerces. How can I verify this? Also, here is how I'm invoking the parser.
Thanks
Code snippet
----------------------------------------------------------------
_XmlDOMParser->setEntityResolver(resolver);
_XmlDOMParser->setValidationScheme(_XmlDOMParser->Val_Always);
_XmlDOMParser->setDoSchema(false);
_XmlDOMParser->parse(xmlDoc2Parse);

Hi,
how are you invoking the parsing? Maybe you disabled external enitity
resolution, or you didn't compile a NetAccessor inside Xerces.

Hello guys
I'm getting Xerces parse errors and I believe it is because the entity callouts
can not be located(see below). How do I get Xerces to follow the URL in the
entity callout to resolve this. I'm running Xerces 2.7.0 and not sure if this
feature is supported. Do I need to upgrade Xerces?
