Thank you Peter for the reply.
Yes, i looked at the source folder and i saw the default output folder is build/classes.
Since i am new to Eclipse, i write a small java application consists of one java class resides in the src folder , and one
jsp uses the java class as a bean.
When i ran the program, it gave me this error :
"org.apache.jasper.JasperException:checkuserlogin.jsp(9,0) The value for the useBean class attribute CheckUser is invalid."
I did further research, and i suspected that i received the error because of my checkUser.class was not presented in the webcontent/WEB-INF/classes.
Please correct me if i am on the wrong track, since i try figure it out all how to to fix this error.
Thanks so much in advance,
Minh Tran
