[Jetty]基于Java Servlet的支持WebSocket的服务器

1. JDK安装

www.java.com/zh/download

2. Jetty下载与安装

download.eclipse.org/jetty，下载稳定版，解压到目标路径

2.1 启动Jetty

命令框中cd到根目录下，会看到有个start.jar启动文件，在该目录下，输入 java -jar start.jar

如果顺利的话，会输出以下log：

2012-10-22 16:02:24.988:INFO:oejs.Server:main: jetty-9.0.0-M2 
2012-10-22 16:02:25.040:INFO:oejs.NCSARequestLog:main: Opened /home/gregw/src/jetty-9/jetty-distribution/target/distribution/logs/2012_10_22.request.log

=========================================================================

途中如果输出以下信息：

java.net.BindException: Address already in use 
  at sun.nio.ch.Net.bind0(Native Method) 
  at sun.nio.ch.Net.bind(Net.java:344) 
  at sun.nio.ch.Net.bind(Net.java:336) 
  at sun.nio.ch.ServerSocketChannelImpl.bind(ServerSocketChannelImpl.java:199)

那么说明是port出现了冲突，默认jetty的端口号是8080，那么就把正在使用该端口号的应用关闭，或者通过以下方式，修改jetty的默认端口8080。

 java -jar start.jar jetty.port=8081

==========================================================================

可以输入

java -jar start.jar --help

寻求帮助

==========================================================================

也可输入以下内容，开启HTTP服务

> java -jar start.jar etc/jetty-https.xml

在浏览器中输入 https://localhost:8443/来验证
