我正在尝试为通常部署到Tomcat的应用程序编写一个小型嵌入式Jetty程序。我的应用程序似乎初始化正常但随后Jetty服务器开始抛出与日志记录相关的错误。我的src目录中有一个log4j.properties文件，包括log4j和slf4j-log4j12作为Maven依赖项。知道我错在哪里吗？
谢谢！

这是我的计划：
public class ControlCenter {
public static void main(String[] args) throws Exception {
Server server = new Server( 8080 );
WebAppContext root = new WebAppContext("ControlCenter/Website/", "/controlcenter");
HandlerCollection handlerCollection = new HandlerCollection();
handlerCollection.addHandler(root);
server.setHandler(handlerCollection);
server.start();
}
}
答案 0 :(得分：1)
您选择了错误的JspServlet实现。
它正在寻找基于org.mortbay.jetty的类，这是针对Old Jetty 6及更早版本的。
