----------------解决方案--------------------------------------------------------
高手 这个问题该怎么解决 ？？
----------------解决方案--------------------------------------------------------
连接被拒绝。。。。
看一下是你否能用你的用户名登陆MYSQL，
没遇见过这个问题。。
----------------解决方案--------------------------------------------------------
检查一下mysql的jar包是否在tomcat下的common/lib下，关闭防火墙（有这样的可能）。
----------------解决方案--------------------------------------------------------
我感觉是tomcat的问题 因为 我在别的机子上能行 在我的机子上就不行了 出现这个问题后 我编写的程序也能正常运行 tomcat也能正常启动 但是我就是不知道哪儿出了问题 。
----------------解决方案--------------------------------------------------------
这个应该不是数据库的问题，你作个main函数测试一下能不能连接数据库，要是行，就重新装一下Tomcat好了

jdbc连接错误了阿
telnet host ports
如果运行上面的命令可以连接说明端口正确，再检查一下你的jdbc url看看是不是搞错了
