在eclipse下面建一个java project
建立目录结构如下：
二级目录：
（备注jetty_test是工程的根目录，etc、lib、webRoot为其二级目录）
到jetty的官方网站（http://www.eclipse.org/jetty/）下载jetty的开发包；
我下载的jetty-hightide-8.0.0.v20110901.tar.gz；
把里面的lib目录的jar包和lib/jsp目录下面的jar包导入到工程里面
说明白，其实jetty.xml和webdefault.xml其实是在我下载的
jetty-hightide-8.0.0.v20110901.tar.gz里面的etc目录下面的jetty.xml和webdefault.xml
jetty.xml:

<!-- The following initParameters are supported: -->
<!--
* acceptRanges If true, range requests and responses are
* supported
*
* dirAllowed If true, directory listings are returned if no
* welcome file Forbidden.
*
* welcomeServlets If true, attempt to dispatch to welcome files
* that are servlets, but only after no matching static
* resources could be found. If false, then a welcome
* file must exist on disk. If "exact", then exact
* servlet matches are supported without an existing file.
* Default is true.
*
* This must be false if you want directory listings,
* but have index.jsp in your welcome file list.
*
* redirectWelcome If true, welcome files are redirected rather than
* forwarded to.
*
* gzip If set to true, then static content will be served as
* gzip content encoded if a matching resource is
* found ending with ".gz"
*
* resourceBase Set to replace the context resource base
*
* resourceCache If set, this is a context attribute name, which the servlet
* will use to look for a shared ResourceCache instance.
*
* relativeResourceBase
* Set with a pathname relative to the base of the
* servlet context root. Useful for only serving static content out
* of only specific subdirectories.
*
* aliases If True, aliases of resources are allowed (eg. symbolic
* links and caps variations). May bypass security constraints.
*
* maxCacheSize The maximum total size of the cache or for no cache.
* maxCachedFileSize The maximum size of a file to cache
* maxCachedFiles The maximum number of files to cache
*
* useFileMappedBuffer
* If set to true, it will use mapped file buffer to serve static content
* when using NIO connector. Setting this value to false means that
* a direct buffer will be used instead of a mapped file buffer.
* By default, this is set to true.
*
* cacheControl If set, all static content will have this value set as the cache-control
* header.

而webdefault.xml基本可以不改，因为它是用来标识文件的语言格式，基本的一些配置；
jetty.xml我们可以做一定的修改；
例如说我们可以改下服务监听的端口号，如图：
web.xml：
（备注就是web请求的配置信息，例如说设置servlet的路由）
如下面配置：

JettyServerStart.java：启动类，入口
package org.jetty.demo;
//启动类，入口
public class JettyServerStart {
public static void main(String[] args) {
JettyCustomServer server = new JettyCustomServer(
"./jetty/etc/jetty.xml", "/testContext");
server.startServer();
}
}
运行这个类相当于启动了整个工程：
访问index.jsp
http://localhost:8080/testContext/index.jsp
访问HelloWorldServlet：
http://localhost:8080/testContext/servlet/HelloWorldServlet
