就是一个简单的程序计数器，我把那个count.txt放在和这个文件相同的目录下，但是她说找不到，
然后又改称绝对路径，他说：
C:\jakarta-tomcat-5.0.19\work\Catalina\localhost\myproject\org\apache\jsp\Text_jsp.java:56: illegal escape character
String countFile="C:\jakarta-tomcat-5.0.19\webapps\myproject\count.txt";
^
郁闷，真是为了什么，高手知道一下，谢谢

应该这样使用 \\
或者使用 /
这两个符号等价
但是一个 \ 是转意符
