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？
------解决方案--------------------
看你这个文件啊：reg.jsp
------解决方案--------------------
没有找到这个BEAN
------解决方案--------------------
class= "user "
试试class= "包名.user "
------解决方案--------------------
<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
------解决方案--------------------
可能是没配置好。。。也有可能名字等不对应，仔细检查检查吧
