JSP in /WEB-INF returns "HTTP Status 404 The requested resource is not available"
I created a JSP file.
sample.jsp
<%@ page pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<title>Insert title here</title>
</head>
<body>
This is jsp program
</body>
</html>
I placed it here in the samplejsp project.
samplejsp
`-- WebContent
`-- WEB-INF
`-- sample.jsp
I opened it on the following URL.
http://localhost:8080/samplejsp/sample.jsp
But it shows the following error in browser.
404 ERROR
The requested resource (/sample.jsp) is not available.
Answer
404 simply means "Not Found".
Either the URL is wrong (note: case sensitive!), or the resource is not there where you think it is.
Just verify the URL and/or verify if the resource is there where you'd expect it to be. You placed sample.jsp in /WEB-INF folder. This way it is not publicly accessible without calling through a front controller servlet.
Put it outside /WEB-INF.
samplejsp
`-- WebContent
|-- WEB-INF
`-- sample.jsp
If you want to keep it in /WEB-INF, then you need to create a front controller servlet which forwards to it in doGet() method as below.
request.getRequestDispatcher("/WEB-INF/sample.jsp").forward(request, response);
Finally "open" the JSP by just calling servlet's actual URL instead of JSP's fictive URL.
