從Alfred文章中扣出來的，以前到是沒有用過這種方法，收錄收錄：）：

package com.wisekernel;

import org.mortbay.http.SocketListener;

public class Jetty5 {

    /**

    public static void main(String[] args) throws Exception {
        Server server = new Server();
        SocketListener listener = new SocketListener();
        listener.setPort(8080);
        server.addListener(listener);
        server.addWebApplication("/", "./WebRoot");

}

EmbededTomcat 的createContext()方法中寫入的應該是Web App的絕對路徑。這點不如Jetty來的方便，Jetty可以寫相對路徑。
EmbededTomcat 的項目classpath中不能有XerecsImpl.jar，否則會報錯，這個bug不知道怎么fix。
