java.lang.UnsatisfiedLinkError: tcnative-1.dll: Can't load AMD 64-bit .dll on a IA 32

在myeclipse启动tomcat的时候会报错。见下文：

解决办法，去该地址下载一个32位的dll文件，替换tomcat的bin\目录下对应的文件

According http://netbeans.org/bugzilla/show_bug.cgi?id=195146, it caused by the 32bit and 64bit incompatible.

You can download the 32bit from http://www.apache.org/dist/tomcat/tomcat-connectors/native/1.1.20/binaries/ to replace...
