Thanks!
It doesn't complain about login.jsp. It complains about /login.do. Did you deploy this app as the root web app in tomecat? Otherwise, it's under a context path, and you need your action to be something like /myWebApp/login.do.
In any case, the right thing to do is to prepend the context path:
action="${pageContext.request.contextPath}/login.do"
or, using the JSTL:
action="<c:url value='/login.do'/>"

It doesn't matter if you're using Ajax call or not, the request should reach to the desired controller.
With that being said, and the fact you wrote that the request doesn't even reach to its destination, then your problem is within your URL.
I would recommend using the Spring Url tag which is a part of Spring tag library. It will help you build your URL within your JSP files.
In your URL example, you obviously missing the complete URL, I believe it should be: http://localhost:8080/your_project_name/hello
So just do this:
add the next directive to your JSP file:
<%# taglib uri="http://www.springframework.org/tags" prefix="spring" %>
use the spring url tag within you Ajax call:
$.ajax
({
type: "Post",
url: '<spring:url value="/hello"/>',
success: function(resp){
alert(resp)
}
});
So the final result of your JSP should be:
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%# taglib uri="http://www.springframework.org/tags" prefix="spring" %>

I'm new in Spring. I have excercise to make a Web app where the file is uploaded and then written to database. I'm making it with Spring MVC and Maven in Netbeans.
I made a fully working basic project based on this tutorial
https://saarapakarinen.wordpress.com/2015/01/11/building-a-basic-spring-3-web-project-netbeans-and-maven/
And tried to expand it for my application, wanted to make file uploading component based of official Spring tutorial
http://docs.spring.io/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-multipart
but its not working, got an error:
HTTP Status 400 - Required MultipartFile parameter 'file' is not present
I've expanded this project with wyslij.jsp (form for upload file)
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

</head>
<body>
<form method="get" action="http://localhost:8084/Hello/application/wyslij" enctype="multipart/form-data">
<input type="file" name="file"/>
<input type="submit"/>
</form>
</body>
</html>
And added Controller for uplading file called UpladController.java
package helloweb;
import java.io.IOException;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.multipart.MultipartFile;
#Controller
public class UploadController
{
#RequestMapping(value = "wyslij", method = RequestMethod.GET)
public String handleFormUpload(#RequestParam("file") MultipartFile file) throws IOException
{
if (!file.isEmpty()) {
byte[] bytes = file.getBytes();
// store the bytes somewhere
return "redirect:tak";
} else
{
return "redirect:nie";
}
}
}

Could someone tell, why is an error and explain?
EDIT:
I decided to use form.jsp and HelloController.java made in tutorial and convert it to file upload (they were working more than my code)
form.jsp
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Form Page</title>
</head>
<body>
<form method="POST" enctype="multipart/form-data" action="http://localhost:8084/Hello/application/form">
<label>file to send: <input type="file" name="file" /></label>
<input type="submit" />
</form>
</body>
</html>
and HelloController.java
package helloweb;
import java.io.IOException;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.multipart.MultipartFile;
#Controller
public class HelloController
{
#RequestMapping(value = "form", method = RequestMethod.POST)
public String login(#RequestParam(value = "file", required = true) MultipartFile file) throws IOException
{
if (!file.isEmpty())
{
byte[] bytes = file.getBytes();
// store the bytes somewhere
return "redirect:tak";
}
else
{
return "redirect:nie";
}
}
#RequestMapping("form")
public String viewLoginPage(Model model)
{
return "form";
}
}
Now I have at least file upload form displayed properly at start page, but after selecting a file and click button, I get antoher error:
HTTP Status 500 - Could not parse multipart servlet request; nested exception is java.lang.IllegalStateException: Unable to process parts as no multi-part configuration has been provided
Chnaged and Controller now is:
#Controller
public class UploadController
{
#RequestMapping(value = "wyslij", method = RequestMethod.POST)
public String handleFormUpload(#RequestParam("file") MultipartFile file) throws IOException
{
if (!file.isEmpty()) {
byte[] bytes = file.getBytes();
// store the bytes somewhere
return "redirect:tak";
} else
{
return "redirect:nie";
}
}
}
and the jsp:
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Wysylanie pliku</title>
</head>
<body>
<form method="post" action="http://localhost:8084/Hello/application/wyslij" enctype="multipart/form-data">
<input type="file" name="file"/>
<input type="submit"/>
</form>
</body>
</html>
tested service with postman
result for GET test:
HTTP Status 405 - Request method 'GET' not supported
type Status report
message Request method 'GET' not supported
description The specified HTTP method is not allowed for the requested resource.
result for POST test:
HTTP Status 400 - Required MultipartFile parameter 'file' is not present
type Status report
message Required MultipartFile parameter 'file' is not present
description The request sent by the client was syntactically incorrect.
You are sending file with multipart/form data encoding which needs Http POST. In your controller change it to post like below.
#RequestMapping(value = "wyslij", method = RequestMethod.POST)
And in your jsp as well.
<form method="post" action="http://localhost:8084/Hello/application/wyslij" enctype="multipart/form-data">
<input type="file" name="file"/>
<input type="submit"/>
</form>
I have a Spring MVC controller which maps test to test.jsp. It has ModelMap object which has to be accessed by JSP page.
Here is controller
#RequestMapping(value = "/test")
public String test(ModelMap map)
{
map.addAttribute("data","the string which should bbe printed");
return "test";
}
Here is test.jsp
<%# page language="java" contentType="text/html; charset=UTF-8"

PROBLEM:
When I click on the submit button, it shows me the error:
**type Status report
message /Apontador_Web/LoginPage
description The requested resource is not available.**
And When I remove the tags "listener" and "context-param"
it loads the servlet.
What can be happening?
go to glashfish server output and look for an some exception
Tell me the name off exception
print all
You will need to add #WebServlet(urlPatterns={"/LoginPage"}) above your class name i.e public class LoginPage extends HttpServlet {
