Question

我正在尝试从Java应用程序运行嵌入式Jetty服务器。战争在\ WEB-INF \ lib中有其自己的罐子。我的Java应用程序有自己的工作来定期运行任务，并且有自己的类路径。下面是我启动Jetty服务器的代码。

WebAppContext wac = new WebAppContext();
wac.setContextPath("/test");
wac.setWar(applicareHome + "/warpath");
server.addHandler(wac);
server.setStopAtShutdown(true);
try {
    server.start();
} catch (Exception e) {
    e.printStackTrace();
}

当我运行Java应用程序时，似乎Java应用程序中的jar和war文件中的jar之间存在冲突。

下面是我得到的错误。

我应该如何解决此错误？
