Class PluginServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          org.jivesoftware.wildfire.container.PluginServlet

All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class PluginServlet
extends javax.servlet.http.HttpServlet

The plugin servlet acts as a proxy for web requests (in the admin console) to plugins. Since plugins can be dynamically loaded and live in a different place than normal Wildfire admin console files, it's not possible to have them added to the normal Wildfire admin console web app directory.

The servlet listens for requests in the form /plugins/[pluginName]/[JSP File] (e.g. /plugins/foo/example.jsp). It also listens for non JSP requests in the form like /plugins/[pluginName]/images/*.png|gif, /plugins/[pluginName]/scripts/*.js|css or /plugins/[pluginName]/styles/*.css (e.g. /plugins/foo/images/example.gif).

JSP files must be compiled and available via the plugin's class loader. The mapping between JSP name and servlet class files is defined in [pluginName]/web/web.xml. Typically, this file is auto-generated by the JSP compiler when packaging the plugin. Alternatively, if development mode is enabled for the plugin then the the JSP file will be dynamically compiled using JSPC.
