Yes, I'd like to define the XML Schema inside the GetFeature Response. When GeoTools is parsing the GetFeature response, it sucks in the schemas it needs to validate the document. Unfortunately when it tries to suck in the schema from my server, it doesn't know how to negotiate basic authentication, so gets a 401 and the document fails validation. The code for the initial GetFeature request is easy to get basic auth working, but the suck in of schemas is deep in the stack and it would be difficult to change every method in the stack to accept authentication arguments. Creating and setting the default Authenticator in a Java application, broadly solves this issue, however in an applet, setting the default Authenticator throws a security exception. I don't want customers to have to bother with signed applets or monkeying around with java policy files. In-lining the schema would alleviate me of any code changes on the client end, that is if the parser knows how to deal with in-line schemas. Below is an example GetFeature Response and associated schema.

Do you mean defining the XML Schema in the XML instance document (i.e. the GetFeature response) itself? If yes, that's not going to happen. xsi:schemaLocation provides a namespace and URL value for an XML parser to seek the XML Schema document and validate against it. Perhaps I don't understand your problem clearly enough. Do you have full examples of both the XML instance document, as well as the schema it uses? ..Tom > -----Original Message----- > From: UMN MapServer Users List > [mailto:[EMAIL PROTECTED] On Behalf Of Simpson > Sent: Tuesday, 08 November, 2005 16:35 > To: [email protected] > Subject: Re: [UMN_MAPSERVER-USERS] WFS Inline Schema > > > Something along the lines of below xml. > > When the namespace http://www.ttt.org/myns points to a URL > back on the server it came from, the XML parser in GeoTools > tries to GET the document but can't since I have basic auth > running on the server and the XML parser doesn't know how to > authenticate.
