Always getting "Server returned HTTP response code: 503 for URL: http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd" in client

[anonymous]

We always get the following exception in our Java XmlRpcClient.

Could it be that you download the DTD in the server implementation? Could you disable this?

(because of spam control I had to change the url to <SAMVE URL>)

Are you running RPC from latest trunk? Earlier the plugin (and the underlying method implementations from Trac core) would raise TracError a lot - this error in regular Trac response handling will return a HTML error page. The DTD your client tries to fetch is likely coded into the Trac xhtml template.

Latest version of TracRPC (trunk) should not return any such pages, and in case of errors it will return proper faults/errors adapted to the protocol or in worst case return a text/plain response.

Please check again and let mw know how it works out.
