Hi to all

I need help from a Taverna hacker !!! I not a JAVA programmer so I'm a
bit lost...anyway here is the problem

W3C is using some "tarpits"  due to "applications making excessive
requests for DTD and other schemata". Basically the W3C servers are are
taking a some time to reply when systems starts asking for schemas so
that they can validate XML/WSDL

I am running several web services that have extensive schemas that are a
bit like a maze (welcome to the OGC world) and some schemas call
http://www.w3.org/2001/xml.xsd  that in turn takes some time to reply
until the parsing code of Taverna gives up e.g:

WSDLException (at /definitions/types/schema[1]/schema):
faultCode=OTHER_ERROR: An error occurred trying to resolve schema
referenced at 'http://www.w3.org/2001/xml.xsd', relative to
'http://schemas.opengis.net/ows/1.1.0/owsExceptionReport.xsd'.: Server
returned HTTP response code: 503 for URL:
http://www.w3.org/2001/xml.xsd: java.io.IOException: Server returned
HTTP response code: 503 for URL: http://www.w3.org/2001/xml.xsd
    at
sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1441)
    at java.net.URLConnection.getContent(URLConnection.java:688)

So, W3C recommends the use of XML catalogs in your local machine, I've
implemented this solution in xmllint (libxml) and it works fine, now
I've to implemented it in the JAVA libs used by Taverna, and I'm lost, I
know that Taverna uses Axis for web service and in turn Axis should be
using Xalan or something similar, but I am not finding any extra
information or even a guide-for-java-dummies

Any tips, suggestions, on how to deal with it ?!
