Jetty代理类NotFoundException

Question

我正在尝试将Jetty配置为http和https的代理。我下载了两个不同版本的jetty，但我都有相同的问题。

我目前使用的版本是：jetty-分发-8.1.8. v20121106，运行在CentOs 6.2上。

打开焦油包装后。gz，我修改了开始。ini文件添加etc/jetty代理。xml到配置文件列表：

#etc/jetty-jmx.xml
etc/jetty.xml
<b>etc/jetty-proxy.xml</b>
etc/jetty-annotations.xml
etc/jetty-ssl.xml
# etc/jetty-requestlog.xml
etc/jetty-deploy.xml
#etc/jetty-overlay.xml
etc/jetty-webapps.xml
etc/jetty-contexts.xml
etc/jetty-testrealm.xml

码头定期启动。我可以通过以下方式访问它：

http://localhost:8080/
https://localhost:8443/

读取日志文件时，似乎在端口8080、8443和8888上启动了三个抽象连接器：

2012-12-04 12:40:03.400:INFO:oejs.AbstractConnector:Started SelectChannelConnector@0.0.0.0:8080
2012-12-04 12:40:03.666:INFO:oejus.SslContextFactory:Enabled Protocols [SSLv2Hello, SSLv3, TLSv1] of [SSLv2Hello, SSLv3, TLSv1]

2012-12-04 12:40:03.732:INFO:oejs.AbstractConnector:Started SelectChannelConnector@0.0.0.0:8888

当我配置浏览器以访问端口8888上的代理时，jetty出现以下异常：

我已经验证了文件夹$JETTY_HOME/lib包含jar文件：

jetty-client-8.1.8.v20121106.jar 

它包含HttpExchangeorg.eclipse.jetty.client.类。要执行jetty，我使用命令：bin/jetty.shstart

指挥箱/码头。sh check返回以下信息：

Jetty running pid=15498

非常感谢。

在开始的选项中。ini添加客户端时，代理环境要求客户端工件可用。与使用ProxyServlet相同，您需要在servlets web inf/lib目录中包含jetty客户端及其依赖项。

无论如何，这将向您展示可能的选项以及在您运行它时它是如何进入类路径的。start.jar确实有助于构建jetty运行的环境。

java-jar启动。jar—列表选项

这将通过为您提供给定配置的示例命令行来向您展示当前的设置方式：

java-jarstart.jar--dry-run
