Answer 3

用户权限的问题。
我猜测你用的是VISTA，需要用  administrator权限。试试吧。

Answer 4

自己装TOMCAT,然后通过Eclipse来调用启动.这样比较好控制点,也方便有时候在自己的机子上小小的发布一下玩玩..呵呵.

Answer 5

java.net.SocketException: java.net.ConnectException: Connection refused: connect
检查数据链接情况
排除后
在试试其他解决方案
祝
早日解决

Answer 6

可能是连接问题，还有可能就是你在发布之前tomcat没有关闭，先关闭在重新启动试试！

Answer 7

javax.servlet.UnavailableException: Initializing application data source conmysql
应该是你在Tomcat中配置的数据源的问题

Answer 8

谢谢大家，我把原来的TOCMAT删掉，重装了一下就可以了
