这是什么问题啊->JSP
在请求页面：http://127.0.0.1:8080/webapp/reg.jsp
时提示下面异常
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
org.apache.jasper.JasperException: /reg.jsp(3,0) The value for the useBean class attribute user is invalid.
org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:39)
org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:405)
-------------------------------------------------
org.apache.jasper.JasperException: /reg.jsp(3,0) The value for the useBean class attribute user is invalid.
是什么原因引起的？
[解决办法]
看你这个文件啊：reg.jsp
[解决办法]
没有找到这个BEAN
[解决办法]
class= "user "
试试class= "包名.user "
[解决办法]
<jsp:useBean id= "user " scope= "session " class= "user ">
这里 class= "user " 不对,应该把包名放一起,比如class= "com.microsoft.aaa.user ",这里 "com.microsoft.aaa "是包名
[解决办法]
可能是没配置好。。。也有可能名字等不对应，仔细检查检查吧
