我正在编写一些servlet并且它们都运行良好Tomcat没有运行什么问题。然后我编写了一个使用JERSEY的类文件,当我尝试运行它时,Tomcat无法启动。我在Eclipse中安装了Web开发工具插件,每次点击编译我都会
java.lang.ClassNotFoundException:javax.servlet.ServletContainerInitializer
以下是控制台的输出

这是如何引起的?如何解决?
答案 0 :(得分:10)
javax/servlet/ServletContainerInitializer
是Servlet 3.0
中的一个类,在Tomcat 6中不支持。
你的CLASSPATH中的某个地方可能有servlet.jar
,它不应该。这真的会弄乱类加载器,因为Tomcat的类加载器没有像预期的那样正常运行(参见上面的链接)。 servlet.jar
只应在$CATALINA_HOME/lib
中找到一次。
答案 1 :(得分:5)
有时,如果您在Eclipse中运行Tomcat服务器,则本地Tomcat工作目录可能会被抬高,您必须明确清除它。请注意,这与在项目上执行Clean构建不同: 从“服务器”窗口: 右键单击您尝试启动的服务器 - >清除Tomcat工作目录...->确定

我今天也遇到了同样的问题。最终结果是用户库变空了。但是,显示的错误消息没有给出任何提示。
答案 4 :(得分:0)
迟到的答案,但这可能对某人有所帮助。
我相信这是因为Jersey是使用较新的java版本创建的,并且您尝试在较旧版本的java中运行它。更新您的Java版本或下载支持您的Java版本的旧版Jersey。
Window -> Preferences -> Java -> Compiler -> set "Compiler compliance level" to 1.7.
来自Jersey文档:
Until version 2.6, Jersey was compiled with Java SE 6. This has changes in Jersey 2.7.
Now almost all Jersey components are compiled with Java SE 7 target. It means, that
you will need at least Java SE 7 to be able to compile and run your application
that is using latest Jersey. Only core-common and core-client modules are still
compiled with Java class version runnable with Java SE 6.
