Question

这是一个非常基本的例子。我想使用下面的jetty加载Web应用程序。

public static void main(String[] args) throws Exception {
    Server server = new Server(8085);    
    WebAppContext webapp = new WebAppContext( "D:/workspace/camel/TestWithGradle/src/main/java/sample.war" , "sample");
    webapp.setExtractWAR(true);
    webapp.setParentLoaderPriority(true);


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

战争是https://github.com/heroku/heroku-deploy/blob/master/spec/resources/sample-war.war 这是一个非常简单的使用jsp文件和java servlet的战争。

但是，我运行这个应用程序，控制台给出了异常..

请帮我详细解释一下。感谢阅读和你的时间。

您的XML具有错误的DTD或名称空间声明。

启动尝试从远程URL获取某种资源，用于验证XML。

对于正常的码头分布或普通的码头工件，这不会发生。

首先确保您使用官方的码头罐，不要重新包装它们，不要对它们进行重新包装，不要让它们一个罐子，让它们独自存在（现在）。 / p>

然后确保您的各种XML文件中没有拼写错误。特别是在你的war文件中，以及WEB-INF/lib/*.jar文件的所有内容。可能有一个小错字或引用不够错误，以至于Jetty无法使用jetty jar附带的验证资源来快捷方式远程资源请求。

Jetty加载战争有超时异常
