很可能你的root密码错了。
你是否可以使用
从控制台连接mysql -uroot -p?
Most probably your password for root is wrong.
Are you able to connect from the console using
mysql -uroot -p ?
是的,我只是这样使用。
但是当我从浏览器运行servlet时,我的日志/ catalina中出现了错误.out。
yes,i am using that way only.
But when i ran servlet from browser i get that error in my logs/catalina.out .
当我通过consol时我可以使用数据库。
when i go through consol i could use database.
