关于tomcat 启动不了的问题。

下午6点还用得好好的，在6点30的时候，在conf/server.xml 里添加了几条语句，与 中文注释。
7点关闭tomcat就出现关闭不了的错误提示。7点2分，启动tomcat，命令行文本显示有异常。
通过命令行进入tomcat/bin 目录下，运行catalina.bat
D:/Tomcat 5.0/bin>catalina.bat
Using CATALINA_BASE: D:/Tomcat 5.0
Using CATALINA_HOME: D:/Tomcat 5.0
Using CATALINA_TMPDIR: D:/Tomcat 5.0/temp
Using JAVA_HOME: D:/j2sdk1.4.2_08
Usage: catalina ( commands ... )
commands:
debug Start Catalina in a debugger
debug -security Debug Catalina with a security manager
jpda start Start Catalina under JPDA debugger
run Start Catalina in the current window
run -security Start in the current window with security manager
start Start Catalina in a separate window
start -security Start in a separate window with security manager
stop Stop Catalina
version What version of tomcat are you running?

再在命令行中运行 catalina run。即打印出 异常信息如下：

刚开始好好的，现在出问题，切入点应该在新增加的操作。然后看是编码问题，会不会是添加的中文注释引起的。去掉该中文后，重启tomcat，一切正常了。tomcat里，server.xml 都不支持中文注释的，奇怪。
