--------------------编程问答-------------------- 网上说是工程lib下
的jsp-api.jar和servlet-api.jar与tomcat的lib下的这两个包冲突了
但是我删了以后还是不行 --------------------编程问答--------------------
重启 --------------------编程问答-------------------- 错误提示好像不是简单的包冲突，倒更像是包找不到 --------------------编程问答-------------------- 重启软件？ --------------------编程问答-------------------- 这种包的冲突问题解决了后是要重启的。 --------------------编程问答-------------------- javax.servlet是肯定存在的啊 --------------------编程问答-------------------- 重新发布运行，不可以吗？ --------------------编程问答-------------------- 重启后还是不行。。
这个项目原来是没错的，是以前的一个项目，现在换了台机器，软件版本也高了。。。
就成这样了。。 --------------------编程问答-------------------- 是不是TOMCAT有问题 --------------------编程问答-------------------- 我重装试试。。。 --------------------编程问答-------------------- 还是不行。。。 --------------------编程问答-------------------- 还没用过tom7，不过提示的不是找不到包么= =！
清理下所有配置的路径吧 --------------------编程问答-------------------- 应该是缺少servlet-api.jar吧
补充：Java , Web 开发
