我想使用Jetty启动我的应用程序，因此我已经添加了下面提到的依赖项。当我运行主方法时，Jetty成功启动。（我正在开发一个struts2+spring3+hibernate maven项目，我也可以在tomcat中部署它）
现在我想从war打包的pom文件中创建可执行的jar文件。所以我在我的pom中添加了maven-assembly-plugin。（我尝试过maven jar插件，但它没有添加依赖项）

main method

System.setProperty("is_DCA", "YES");
WebAppContext webAppContext = new WebAppContext();
webAppContext.setResourceBase("/home/myfolder/workspace/app/dca/src/main/webapp");
webAppContext.setDescriptor("/home/myfolder/workspace/app/dca/src/main/webapp/WEB-INF/web.xml");

启动应用程序
我使用 java -jar /home/myfolder/workspace/app/dca/target/app-dca-1.0-jar-with-dependencies.jar 命令运行创建的 jar 文件。
然后，Jetty 出现异常。

有没有可能使用创建的war文件启动jetty。它在/WEB-INF/lib/文件夹中有jar文件，所有属性文件和xml文件都在/WEB-INF/lib/中，我尝试运行war文件
java -jar /home/myfolder/workspace/app/dca/target/app-dca-1.0.war
但它无法找到主类。
当创建可执行的war文件时，通过sumit的答案解决了问题
我遇到了这个问题的异常。当我将jetty版本替换为7.6.7.v20120910时，它可以工作。
我不知道为什么它不能与jetty 8.1.10.v20130312一起工作。
