Re: External schema validation using Xerces from behind a proxy

Hi Emmanuel,
you can also try to rebuild Xerces using libWWW 
as NetAccessor; I am not sure if the API used 
include support for proxy servers, but you can 
then try to set the environment variable 
http_proxy="http://your.proxy.server:8080/"; and
no_proxy="cern.ch,ncsa.uiuc.edu,some.host:8080" 
before running your application.
