Usage

From source file:org.getobjects.jetty.WOJettyRunner.java

/**
 * This prepares and configures the Jetty server. It sets up the Servlet
 * context and configuration to point to the WOServletAdaptor class.
 * <p>/*  ww  w .  jav a2 s.  co m*/
 * Flow:
 * <ol>
 *   <li>a jetty.Server object is setup with a port
 *   <li>a servlet.Context object is attached to the server with the appname
 *   <li>a ServletHolder objects is created as a factory for WOServletAdaptor
 *       and holds all the 'init parameters' (properties)
 *   <li>the ServletHolder is added to the servlet.Context (as / which is
 *       /AppName/ with the prefix of the Context itself)
 * </ol>
 * Note: no WO objects are instantiated at this point.
 * <p>
 * Finally the app can have a public 'www' directory with static resources
 * (either as a 'www' subpackage, or pointed to by WOProjectDirectory, or
 * in the current directory).<br>
 * All files/dirs within that are publically exposed in the Jetty root (NOT
 * below the app entry point, e.g.: /images/banner.gif).
