求助,关于tomcat闪退

[LeeDEM0N]

具体情况是这样的,tomcat在没有修改过server.xml的时候,运行没有报错,但是在server.xml里配置一个Context标签再重新打开startup.bat就闪退了..

报错的日志如下:

应该是webapps中的自带文件夹删除了，这个应该只影响端口登录吧

你用什么东西打开的server.xml 看下是不是编码有问题了。

[执笔记忆的空白]

警告: Catalina.start using conf/server.xml: com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: 1 字节的 UTF-8 序列的字节 1 无效。 难道改过server.xml,并且保存的时候，编码变成了utf-8
