Tomcat Can't load AMD 64-bit .dll on a IA 32

 在eclipse中启动tomcat，出现以下错误：

错误信息：“Tomcat Can't load AMD 64-bit .dll on a IA 32”

错误信息提示很明显，也就是tomcat启动时加载的jvm是32位的版本，加载错了，由于我本地还有个64位的版本。因此要切换下，以下图：

myeclipse里面Windows-》preferrence-》tomcat,

因为我部署的是tomcat7,因此在tomcat7的JDK配置中，选用64位的版本1.7（我本地装了32位版本1.6），

切换好后，再次启动就OK了~
