Hi Rupinder, For your case of customizing the group features of XWiki, you should be looking into the following class, com.xpn.xwiki.user.impl.XWikiRightServiceImpl.java. Precisely the following method can be used to control the authorization process, checkAccess(String, XWikiDocument, XWikiContext) To create groups, add users to groups you need to fetch the handle from the context, as context.getWiki(), and you will be GTG. Thanks & Regards, Pradeep Chellur -----Original Message----- From: devs-bounces(a)xwiki.org [mailto:devs-bounces@xwiki.org] On Behalf Of rupinder.singh(a)wipro.com Sent: Wednesday, March 11, 2009 7:02 AM To: devs(a)xwiki.org Subject: [xwiki-devs] Customizing XWiki to integrate with a SocialNetworking Site Hi Devs, I have a requirement to customize XWiki to integrate with Communities in a Social Networking Site that I am developing. Members of a Community should be able to view/edit documents created by other members of the same community but they should not be able to view/edit documents created by members of other communities. Essentially, we want to introduce a 'Community Scope' in XWiki. The number of communities and members grows with time, obviously. I think such a feature is not available out of the box. I am planning to do some customization on the Groups feature of XWiki to achieve this requirement. Here is an outline of the approach. 1. When a new community gets created in the social site, create a new Group of corresponding name in XWiki programatically. (need to know what API to call). 2. When a user joins a community, automatically add the user to the XWiki group associated to that community. 3. When a user creates a new document in the community's XWiki, gives rights to the associated community's Group to that document. The Rights module of XWiki will automatically take care of the authorization when that document is requested by any user. The challenge seems to be identifying the right places in code to make changes for 1 and 3. (#2 I can try to achieve by overriding XWikiUser.isUserInGroup() to plugin my custom implementation). Any pointer in this regard will be greatly appreciated. If there is an alternative approach to what I am planning, that would be great too.
