问题:

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.

回答1:

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.

回答2:

It\'s mostly related to your directory structure or packaging.
Can you please add your directory structure?

Similar to below -

src 
|-html\\
|-jsp\\

Perhaps this should do it

<form action=\"sample.jsp\" method=get>
      <input type =submit value=\"submit\">
</form>

Edit - WEB-INF does not allow direct access to JSP.

JSP in /WEB-INF returns “HTTP Status 404 The reque
