使用嵌入式jetty服务器运行Web应用程序(WAR)

Question

我做了一个非常基本的Web应用程序,只有一个html页面.我把它作为战争出口了.

现在我创建了一个嵌入式jetty服务器.

public class SimplestServer {

public static void main(String[] args) throws Exception{
    Server server = new Server(8000);

    WebAppContext webapp = new WebAppContext();
    webapp.setContextPath("/");
    webapp.setWar("C:\\Users\\User\\Desktop\\jetty\\JettyWar.war");
    server.setHandler(webapp);

    server.start();
    server.join();
}

}

我为这个嵌入式服务器创建了一个jar.但是当我尝试通过嵌入式服务器运行我的Web应用程序时,出现以下错误.

我用过码头8.1.14.当我在目标运行时选择j2ee预览时,我无法理解为什么我得到apache没有类def错误.顺便说一句,当我在运行时使用apache tomcat时,我得到了同样的错误.

另请注意,我不使用maven或ant.我也不想使用它们.我希望只通过简单的java来实现.

提前感谢您的帮助.

一个简单的解决方案是使用jetty-runner.jetty-runner jar直接嵌入码头分布(<groupId>org.mortbay.jetty</groupId> <artifactId>jetty</artifactId>)

然后在你的主要课程中你只需要做那样的事情:

jettyRunner = new JettyRunner("/yourContext", "path/to/your/webApp", port);
    jettyRunner.start();
