[xwiki-users] Problem with xwiki rpc: 503 when requesting w3.org DTD on response parsing

I'm attempting to use the Java XML-RPC interface to xwiki, but I'm running into problems. Specifically, when the xml-rpc library attempts to parse the response of the rpc call, it's attempting to request a DTD from w3.org, which returns a 503 status code. W3C is returning the 503 because they are tired of poorly configured client libraries continually requesting largely static DTD documents, as described here: http://www.w3.org/blog/systeam/2008/02/08/w3c_s_excessive_dtd_traffic Everyone's answer to this problem seems to be "use XML catalogs", but there is no way that I've found to configure xml catalogs, especially when the underlying xml parser is wrapped in not one, but two, layers of client library (xwiki -> apache ws xml rpc). Anyone run into this issue? Anyone have any possible solutions? Thanks, Brian
