Class AbstractCinnamonServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          org.spicefactory.cinnamon.web.AbstractCinnamonServlet

All Implemented Interfaces:

Serializable, Servlet, ServletConfig

Direct Known Subclasses:

CinnamonServlet, SpringCinnamonServlet, XmlCinnamonServlet

public abstract class AbstractCinnamonServlet
extends HttpServlet

The abstract base Servlet for processing HTTP based AMF3 requests.

There are to concrete implementations, one using Spring for configuration and one using Cinnamon's own XML configuration format. But alternatively you could also create your own subclass of this base servlet and use a custom ConfigurationBuilder implementation.

The Servlet is just a very thin layer on top of the Cinnamon framework, so most parts of the framework (except for the web package) do not depend on the Servlet API or HTTP protocol. This decoupling may be useful for testing or unusual deployment scenarios.
