Question

为什么我的Jetty 8启动失败了HttpServlet响应的ClassNotFoundException？我错过了什么步骤？

在Ubuntu 12.04.03上运行

我安装了openjdk 7：

sudo apt-get install openjdk-7-jdk

安装了码头8：

sudo apt-get install jetty8

修改/ etc / default / jetty8文件以设置NO_START = 0＆amp; JAVA_HOME = ...值。

但是当我用“service jetty8 start”启动jetty时它会失败，并且/var/log/start.log会显示：

引起：java.lang.ClassNotFoundException：javax.servlet.http.HttpServletResponse

完整堆栈跟踪是：

请尝试使用此版本：

sudo apt-get install libservlet3.0-java

您需要获得与您的servlet-api版本匹配的实现。
