[xwiki-users] XWiki Eclipse connection problem

Hello, I'm trying to connect to my XWiki 1.9.2 instance using XWiki Eclipse. In the XWiki connection settings dialog box, the field "Server URL" is set to "http://<server>/xwiki". And when I click on Finish, I get the following error message : Error connecting to remote XWiki: 'Failed to create input stream: Server returned HTTP response code: 401 for URL: http://<real_server>/xwiki/bin/login/XWiki/XWikiLogin;jsessionid=79C01C68A222CC518927BECE744B53F2?srid=W0osUbgb'. Please check your settings. I know that 401 is for Unauthorized but my username and password are valid. Is there something to configure in xwiki.cfg ? Could anyone help me ? Thank you. Maxime Mathieu
