A special app which makes at your disposal the Magnolia's Groovy interactive console bypassing the normal Magnolia's filters chain. This can be useful, for instance, to perform rescue operations on a corrupted Magnolia instance. Warning: All operations are executed in system context, meaning that no security restrictions are enforced which might expose your data to risk of irreversible damages if you are not aware of what you are doing. In other words, use it at your own risk.
To use it, in your web.xml you must explicitly comment out the Magnolia filter chain part and add or uncomment the Vaadin servlet. For a sample configuration, see the web.xml fragment below:

   [...]
   <!--
   <filter>
     <display-name>Magnolia global filters</display-name>
     <filter-name>magnoliaFilterChain</filter-name>
     <filter-class>info.magnolia.cms.filters.MgnlMainFilter</filter-class>
   </filter>
   <filter-mapping>
     <filter-name>magnoliaFilterChain</filter-name>
     <url-pattern>/*</url-pattern>
     <dispatcher>REQUEST</dispatcher>
     <dispatcher>FORWARD</dispatcher>
     <dispatcher>ERROR</dispatcher>
   </filter-mapping>
   -->
   <servlet>
     <servlet-name>Vaadin</servlet-name>
     <servlet-class>com.vaadin.server.VaadinServlet</servlet-class>
       <init-param>
        <description>Groovy Rescue App</description>
        <param-name>UI</param-name>
        <param-value>info.magnolia.module.groovy.rescue.MgnlGroovyRescueApp</param-value>
       </init-param>
   </servlet>
   <servlet-mapping>
      <servlet-name>Vaadin</servlet-name>
      <url-pattern>/*</url-pattern>
   </servlet-mapping>
  [...]
 

Once configured and having restarted the web container, you can access the console like this http://server[:port]/contextname

If you need to restart the app, you can append the Vaadin ?restartApplication to the URL.
