Hi Jerome, Thanks for quick reply and valuable input . Infect from last 20 days , I am doing R&D on wiki, which are having free source code. During these only, I came to know about xWiki workspace product. Definitely you have relevant question, what I want? I am developing one product. That product also having requirement of workspace, where user can work. My Requirement : Individual user is already logged in that my product Profile.jsp page and now end user clicks the "wiki widget" at this page. User should directly go to user page , where he can work with workspace. It should be done without authenticating the user. Since we have already done the authentication at boot level. We are using Ubentu. Only due to this, I required source code and I want to understand that how it is written. How session is maintained in "xWiki Workspace"? So I have lot of question in my mind. I hope , you all will guide me for doing this configuration with my product. Please let me know if you have question about my requirement. Since till date I am only studing the documents about xWiki. Now started planning for configuring it with my product. Defnitely I hope your guidence.
