部署 Jetty 服务器时出现 ClassNotFoundException

【问题标题】：ClassNotFoundException when deploying Jetty server部署 Jetty 服务器时出现 ClassNotFoundException
【发布时间】：2021-02-07 17:49:56
【问题描述】：

我正在尝试部署一个 Jetty9 应用程序，我按照客户给出的一些松散的指示安装了该应用程序。我已经能够在端口8081 上启动服务器，当我进行curl localhost:8081 测试时，它一直给出404 错误。

然后我用以下内容设置/opt/jetty9/contexts/root.xml：

<?xml version="1.0"  encoding="ISO-8859-1"?>

<Configure class="org.eclipse.jetty.webapp.WebAppContext">
  <Set name="contextPath">/</Set>
  <Set name="war">
    /opt/jetty9/myproj/myproj.war
  </Set>
  <Set name="virtualHosts">
      <Array type="java.lang.String">
        <Item>myproj.mydomain.com</Item>
      </Array>
  </Set>
</Configure>

这一切看起来都很好，但是当我启动服务器时，这是我得到的堆栈跟踪：

这里明显的问题是没有 /opt/configuration.properties... 但是我找不到任何文件甚至引用这个文件，或者实际上没有任何关于这个配置应该是什么及其内容的在线信息？我根本不知道jetty，或者实际上是java for web，我想通过部署这个应用程序来帮别人一个忙，但过去几天我一直在碰壁......任何指针都是真的赞赏。谢谢

    【解决方案1】：

    从您发布的堆栈跟踪来看，在我看来，Jetty 已启动并正在启动 Web 应用程序。此 Web 应用程序配置了一些侦听器，并且侦听器正在尝试初始化 ConfigurationManager。

    所有这一切看起来你的中间件安装没问题，网络应用程序仍然需要去询问你的客户这是否与应用程序相关。

    【讨论】：

    • 是的，这与我得出的结论相同，目前正在等待确认。谢谢，祈祷我可以在他们确认后配置其他所有内容..
