Nondescript "Unsupported Content-Type" error when connecting to https Sharepoint web services

[Derek McKee]

I have successfully connected to the web services of an unsecured (http) Sharepoint site. Using similar code and following the same steps, I receive the following error when trying to connect to the web services of a secured (ssl/https) Sharepoint site:

Any ideas why I am getting this error and what it means? If the server is returning a html message with something like a 401 error, why doesn't the error message indicate so, as it did so when I was working on connecting to the unsecured Sharepoint site?

I tried to view the server response messages using Wireshark for more details, but I don't know how to decrypt them and I don't really know what I'm looking for. When connecting to the unsecured site, I was able to see and open HTML/XML responses.

I wrote my code closely following http://davidsit.wordpress.com/2010/02/10/reading-a-sharepoint-list-with-java-tutorial/ and generated WSDL proxy classes using wsimport (java jdk 1.6.0_21),

com.sun.xml.internal.ws.server.UnsupportedMediaException: Unsupported Content-Type: text/html Supported ones are: [text/xml]

Content type for SOAP message should be either text/xml for SOAP 1.1 or application/soap+xml for SOAP 1.2. In your case its text/html that is the reason you are getting this exception.

earlier I created secure client using axis2. You could look at post below.
