Hi there, I got this strange error: I created two folder under the webapps dir of tomcat, one is ch03/jsp/, and the other is ch04/jsp. I put the same file, like first.jsp file in these two jsp folders, and I used the following URL to invoke the jsp file: http://localhost:8080/ch03/jsp/first.jsp The first.jsp file can be loaded by the browser. But if I change the ch03 to ch04, I got the error, said: type Status report message /ch04/jsp/first.jsp description The requested resource /ch04/jsp/first.jsp) is not available. Does anyone know the reason? Thanks a lot.
