Answer 1

No action instance for path /login could be created
The server encountered an internal error (No action instance for path /login could be created) that prevented it from fulfilling this request.

Answer 2

com.serlvet.Login 这个类有吗？？？  配置不知道没有有问题，你看看其他的action访问是否可以，做一个比较之后再看看

Answer 3

userLogin   这个类改成  UserLogin
