tomcat(错误一) 解决启动报错问题一

1.我的系统原来是XP(32位)的,后来换了新电脑win7(64位),用eclipse启动tomcat项目时报错信息为: Can't load AMD 64-bit .dll on a IA 32-bit platform

java.lang.UnsatisfiedLinkError: D:\Program Files\tomcat\apache-tomcat-7.0.59\bin\tcnative-1.dll: Can't load AMD 64-bit .dll on a IA 32-bit platform

二 解决方法:

1.查看jdk信息;是否为64位

如果不是,请到jdk官方网站:http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

下载相对应的jdk版本,建议下载jdk-8u40-windows-x64.exe.

2.查看tomcat是否位64位

查看方法:D:\Program Files\tomcat\apache-tomcat-7.0.59\bin

在cmd里运行,可以查看信息如下:

看到这里，问题原因已经找到了---->AMD 64位的tomcat.

重新到tomcat官方网站:http://tomcat.apache.org/download-70.cgi

下载新的tomcat:32-bit/64-bit Windows Service Installer (pgp, md5, sha1) 

重新安装,并配置好环境后,问题解决！
