Question

当我尝试通过Eclipse在Tomcat 7服务器上加载某些内容时遇到问题。我已经下载了一个示例并尝试了一个示例，但是在我的浏览器中，它仅显示资源不可用。

这是我在服务器上运行示例时得到的。我无法修复ClassNotFoundException。有人知道吗？

它还说在第二个ClassNotFoundException上方两行，“ SCHWERWIEGEND：Servlet / 0001抛出load（）异常”，但是/ 0001是同一工作空间中的另一个Project。

谢谢。

Answer 1

您需要编译代码原因文件（.class）不会生成

Answer 2

具有$ ClassingFound的$ thingy逐字说明了这样的推测，即$ {jsf-listener}是一个无法解析的占位符表达式，因此找不到此类。因此某些配置可能会缺少“ jsf-listener”。但这只是一个推测。

配置类$ {jsf-listener}的应用程序侦听器时出错 java.lang.ClassNotFoundException：$ {jsf-listener}

Answer 3

您的Tomcat工件不包含“ org.atmosphere”库。检查构建WAR文件的方式。如果是Maven，则需要添加库作为已编译的依赖项。
