Hi Vivian, Are you sure that you want to interact with XWiki the old way (using plug-ins) ? Have you read http://platform.xwiki.org/xwiki/bin/view/DevGuide/WritingComponents or probably better for your needs http://platform.xwiki.org/xwiki/bin/view/DevGuide/WritingMacros ?
The context is an XWikiContext object that was the old way of keeping track of the current request, and it had to be passed around from method to method, everywhere in the code. It is progressively being replaced by an execution context managed by an execution manager component. In velocity, if you have programming rights, you may reach the XWikiContext using the velocity context this way: #set( $xcontext = $context.context ) In a plugins, if you read carefully the http://platform.xwiki.org/xwiki/bin/view/DevGuide/CreatingPlugins , you will notice that you have to extends XWikiDefaultPlugin and implements an init method to receive the context that you will passover to the constructor of your plugin API. This way, you will have access to the context in your plugin API as needed through the protected variable context that is initialized at construction time. The plugin API should be instantiated newly for each call to the getPluginApi method of your plugin. This way, the API represent the contextual instance of your plugin during a given request while the plugin itself is a singleton.
