Eclipse Jetty JettyLauncher java.net.SocketException: Unrecognized Windows Sockets error: 10106: create

刚开始还好好的，突然间出然这个错误，于启动不了了。
XP SP2、Eclipse 3.1.2、Jetty-5.1.11RC0、JettyLauncher 1.3.0
XP SP2、Eclipse 3.2.0、Jetty-5.1.11RC0、JettyLauncher 1.4.1
都不行。
谷歌与摆渡后，看到应当与此无关，而是与网络协议有关的问题，但是没有看到方便的解决办法，怪事，难道真的得重装系统？

问题解决：
Run ==> Run ... ==> Jetty Web ==> Environment
由于我在这里新增加了一个变量，下面默认是
Append environment to native environment，选择这个就可以正常启动的
但是我选择下面的
Replace native environment with specified environment，于是，启动就报错。改选上面的就OK了。

其它问题及技巧：
1、如果JSP出现无法编译：Unable to find a javac compiler时，记得把JDK里的tools.jar加进JRE里去。
即：%JAVA_HOME%/jre/lib/ext/目录下去即可；

2、Jetty、JettyLauncher的配置与使用看自带的文档；

3、网上一些技术文章：
