Class ResourceFileServlet

  • All Implemented Interfaces:
    Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig
    public class ResourceFileServlet
extends javax.servlet.http.HttpServlet
    ResourceFileServlet is a copy of org.mortbay.jetty.servlet.DefaultServlet that has been trimmed down to only support the subset of features that we want to take advantage of (e.g. no gzipping, no chunked encoding, no buffering, etc.). A number of Jetty-specific optimizations and assumptions have also been removed (e.g. use of custom header manipulation API's, use of ByteArrayBuffer instead of Strings, etc.).

    A few remaining Jetty-centric details remain, such as use of the ContextHandler.Context class, and Jetty-specific request attributes, but these are specific cases where there is no servlet-engine-neutral API available. This class also uses Jetty's Resource class as a convenience, but could be converted to use ServletContext.getResource(String) instead.
