[xwiki-devs] [Contrib] Added xwiki-portlet project to contrib/sandbox

Hi devs, I just added a new project, xwiki-portlet, to contrib/sandbox. Its final target is to handle the integration of an XWiki Enterprise instance inside a JSR286 compatible portal. My current approach is to dispatch portlet requests from a portlet (DispatchPortlet) to an XWiki Enterprise instance running on the same context path. I use a servlet filter to catch these requests on the servlet side and to adjust them. I'm rewriting the XWiki URLs from the response, if content type is text/html, into portlet URLs so that the user can navigate through XWiki pages without leaving the portal. XWiki URLs are mapped to portlet URLs (action/render/resource) through configuration (e.g. /bin/download/ prefix is mapped to a resource request type). The current code is not well documented and there are no tests. It's more or less a proof of concept. I'm still investigating if the current approach covers all the use cases. In order to be able to fully integrate XWiki into a portal we must rewrite some of XWiki's UI to ensure it is isolated from the rest of the portal when in portlet mode. This implies: * making sure the CSS doesn't affect content outside of the XWiki container (the container needs to be defined) * namespacing HTML element ids * namespacing JavaScript global variables The last two points are required to allow two instances of the XWiki portlet to be present on the same portal page and have different state. Thanks, Marius
