Student project idea: Cocoon 3 monitoring

* Goal

  Enable JMX monitoring for Cocoon 3 web applications

* Description

  Apart from the basic pipeline implementations Cocoon 3 also provides a framework for RESTful web applications based on XML sitemaps. 
When monitoring a Cocoon application it would be very useful to 

  * inspect the content of the used pipeline caches (cache keys, content)
  
  * be able remove cache entries or clear the whole cache (there might be more than one cache configured!)
  
  * get an overview of all available Servlet-Services (Spring beans), their connections and their mount-points
  
  * get an overview of all other Spring beans
  
  * inspect all settings
  
  * inspect and reconfigure the logging settings (logback)

* Deliverables
  
  * A separate module that exposes the described functionality via MBeans and works with JConsole.
  
  * It might be necessary to refactor the pipeline caching infrastructure in order to expose the required data and to be able to delete cache entries
  
  * It might be necessary to enhance the Cocoon Spring Configurator in order to support a reconfiguration of the logging framework.

* Technologies

  Cocoon 3, Cocoon Spring-Configurator, JMX, Spring 2.5, Log4j, Java
