如果是别的地方移过来的程序 删除里面的 catalina.jar 重新启动 tomcat 参考技术A 端口被占用了，你到tomcat的目录下，有一个server.xml文件，把里面的商品修改下，然后重启下试试追问
可以肯定 不是端口被占用，我tomcat启动 没有报错 亲。只是访问程序出现那个。
参考技术B 看错误提示:org.apache.jasper.JasperException: java.lang.ClassCastException: org.apache.catalina.util.DefaultAnnotationProcessor cannot be cast to org.apache.AnnotationProcessor这问题网上有好多成功解决的例子
ava.lang.ClassCastException: org.apache.catalina.util.DefaultAnnotationProcessor cannot be cast to org.apache.AnnotationProcessor 参考技术C com.huafeng.web.listens.TransmitFilter.doFilter(TransmitFilter.java:51)
，这个应该是你自己的代码，看看这里有什么问题。追问
