Question

我在理解通过tomcat 6.0.33访问我的Web应用程序时抛出的异常跟踪背后的问题时遇到了挑战。以下是详细的异常跟踪。仅供参考。相同的应用程序适用于不同版本的tomcat，但我无法通过6.0.33 tomcat访问我的应用程序。当我甚至访问我的应用程序主页FYI时会发生这种情况。

异常追踪：

Answer 1

好像你已经在Tomcat的工作目录中缓存了来自其他tomcat版本的一些java类。解决您的问题

停止你的tomcat
删除$CATALINA_BASE/work/*
在$CATALINA_BASE/webapps中删除您的网络应用程序的解压缩目录（可能不需要此步骤）
启动你的tomcat。

Answer 2

看起来你的JSP是针对Tomcat 7（预编译）编译的。这些不能在Tomcat 6上部署。

javax.servlet.ServletException：java.lang.NoClassDefFoundError：org / apache / tomcat / InstanceManager
