[Java教程]tomcat部署新的项目的时候出现报错信息: Invalid byte tag in constant pool: 15


上面一堆tomcat启动的提示信息省略掉,下面是报错的具体信息:

 先贴上控制栏的报错信息,以下为解决方式:

首先我把所有部署过得项目都删掉,然后重新启动tomcat之后可以启动成功,并且可以看到欢迎页面,然后依次部署几个自己写的小的servlet测试页面也没有事,正常运行了

可是部署有些项目的时候就给报这个错误了,网上这个错误信息似乎好少,历尽艰辛 终于找到可用的解决办法了,具体如下 贴出来警示自己,造福后人:

{tomcat路径}/conf/web. metadata-complete="true">

  


我的就是红色字体部分没有,添加上去后问题解决可以启动tomcat成功!
