为什么我建的servlet，不能访问？
The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: C:\Program Files\Java\jdk1.7.0\bin;E:\yingyongruanjiananzhuang\TOOLS\Tomcat 5.5\bin

[解决办法]
tomcat版本太老了点嘛，5.5的对应1.5的JDK，你电脑JDK1.7，用tomcat7嘛
[解决办法]
tomcat该升级了，环境不支持。
