I just started working with JSPs and came across one problem.
As I understand, JSP pages under WEB-INF can be accessed via a browser with the URL in localhost:
localhost:8080/MyProject/MyJSP.jsp
However, if I create another sub-folder within the WEB-INF folder (i.e. 'MyFolder') and try to access the same JSP page through the URL:
localhost:8080/MyProject/MyFolder/MyJSP.jsp
it gives an Error 404 instead. Are JSP file navigation systems treated differently to, say, HTML file navigation system?
EDIT: I am using servlets to display my JSP page as such:
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.sendRedirect("MyJSP.jsp");
}
EDIT2: I've changed my redirect to a requestDispatcher as I've been advised to do:
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/WEB-INF/MyFolder/MyJSP.jsp");
dispatcher.forward(request, response);
}
If my @WebServlet is ("/myjsp"), can anyone still access my MyJSP.jsp page if they type localhost:8080/MyProject/myjsp?

No. It's exactly the reverse. Everything under WEB-INF is not accessible by the browser.
It's a good practice to put them there precisely because you never want anyone to access a JSP from the browser directly. JSPs are views, and requests should go through a controller first, which then dispatches (i.e. forwards, not redirects, see RequestDispatcher.forward() vs HttpServletResponse.sendRedirect()) to the right view.
