I'm trying to run this code using tomcat in eclipse

```
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<form action="serv">
<input type="submit">
</form>
</body>
</html>

```

When I click on submit button, the following error message appears

```
HTTP Status 404 - /Ajax/serv

type Status report

message /Ajax/serv

description The requested resource (/Ajax/serv) is not available.

```

I was working on a JSP project without any problems, until I removed the JSP and Servers projects and created new ones. Since then, it's not working.

Any suggestions please?
