Hello, I am Using Apache SOAP to access Webservers that require HTTP 401 Authentication.
From my point of view it is a good idea to let java.net.Authenticator do the work of asking the User for credentials. Benefit 1: via java.net.Authenticator org.apache.soap.util.net.HTTPUtils can not only use Basic auth but also NTLM, Kerberos an everything the underlying JRE provides through java.net.Authenticator. Benefit 2: The Proxy configuration of underlying JRE is used. In Implematation of org.apache.soap.util.net.HTTPUtils that means switch using of java.lang.Socket to using of java.lang.URLConnection, because that anables the Software to use the credentials of java.net.Authenticator. Find attached my "first shot" Reimplementation of org.apache.soap.util.net.HTTPUtils that works for me as a "plugin replacement". Do you think that is a good idea? Thank you, Achim
