Error:

EDIT: It says class 'com.maven.controller.HelloController' not found.
I see that you have put your com.maven.controller.HelloController.java file under src\main\resources folder.
It should be under src\main\java folder. So the hierarchy should be like
src
|-main
|-java
|-com
|-maven
|-controller
|-HelloController.java
The reason is the directory structure followed by maven detects java files only if it's placed under this hierarchy src\main\java, if you are using default configuration.
Can you right click on project and go to Properties > Java Build Path > Source and check whether src\main\java entry is there in the build path list or not? If not add it and try again.

After lots of struggle i got the answer, i had error in spring.xml file. check the solutions.
i need to add below code only in spring.xml file.
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN"
"http://www.springframework.org/dtd/spring-beans-2.0.dtd">
previously i was using below code
<beans xmlns="http://www.springframework.org/schema/beans"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
for above code i need to change pom.xml file, i mean need to add more dependency.
so this is my final spring.xml file for this question only.

No mapping found for HTTP request with URI [/Demo_SpringMVC/add] in DispatcherServlet [duplicate]

This question already has answers here:
Problems with rendering JSP in spring boot
(3 answers)
Closed 2 years ago.
Just trying to create a simple Spring MVC application using maven,but getting this error(No mapping found for request with URL).Tried every possible solutions provided before for these type of error but not getting the correct result.Any help will be highly appreciate .Thank you in advance.
I will try to implement the view resolver part later,here simply trying to show one jsp page after clicking on the submit button on the index.jsp page using spring mvc.

package com.subu;

public class AddController {
#RequestMapping("/add")
public String add()
{
return "display.jsp";
}
}
Project directory is like this:

Not sure it will completely resolve your issue but I see some config issue.
1. Spring is searching for mapping with URL /Demo_SpringMVC/add. Its picking base URL from pom.xml finalName
Do any 1 of following
<servlet-mapping>
<servlet-name>subu</servlet-name>
<url-pattern>/Demo_SpringMVC/*</url-pattern>
</servlet-mapping>
or Map at Controller level like this
#Controller
#RequestMapping("/Demo_SpringMVC")
public class AddController {
#RequestMapping("/add")
public String add()
{
return "display.jsp";
}
}
Doing above will at least trigger add() method. Verify it by adding a sysout.
2. I don't see any View Resolver related configuration. Better to add one, something like below. Also, add JSP's inside WEB-INF folder.
<bean id="viewResolver"
class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/"/>
<property name="suffix" value=".jsp"/>
</bean>

as per your question, error is given below,
No mapping found for HTTP request with URI [/Demo_SpringMVC/add] in
DispatcherServlet with name 'subu'
reason for this error is, not configured the InternalResourceViewResolver in your subu-servlet.xml file. it used to map URI to actual URI. for more info, spring documentation, A Guide to the ViewResolver in Spring MVC
modify the subu-servlet.xml file as following,
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:ctx="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd ">
<ctx:annotation-config></ctx:annotation-config>
<ctx:component-scan base-package="com.subu.*"></ctx:component-scan>
<bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name = "prefix" value = "/WEB-INF/jsp/" />
<property name = "suffix" value = ".jsp" />
</bean>
</beans>
Best Practice
create a folder named "jsp" under the "WEB-INF" folder and move all .jsp files into "jsp" folder. (above answer is based on this tip)

Ok i got it.I was getting the no mapping error due to this line in dispatcher servlet:
<ctx:component-scan base-package="com.subu.*"></ctx:component-scan>
after removing the * from base-package able to get the correct output expected.
<ctx:component-scan base-package="com.subu"></ctx:component-scan>
Regarding the view resolver part,i have not implemented it and still getting the correct output from the display.jsp page.i think View resolver is not required here as i am providing the display.jsp page to the controller myself.

404 error displayed when Spring MVC basic web app is run

I am learning spring MVC. This is a basic code which I found online and trying to run locally. I have added all the dependencies but I am still getting this error:
The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
Here is the code:
This is the landing page which contains the form. On submit, controller will be called.
index.jsp
<html>
<body>
<form action="hello">
UserName : <input type="text" name="name"/> <br><br>
Password : <input type="text" name="pass"/> <br><br>
<input type="submit" name="submit">
</form>
</body>
</html>
This is the maven xml which has the spring dependencies.
pom.xml
Added the below two dependencies:
<!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc -->

In your web.xml <context:component-scan base-package="com.javatpoint" />,but I don't see package com.javatpoint; in your HelloController.You need to create a package and put your contorller in it and set it up in web.xml.
Try to create com.javatpoint package and put your controller in it.
And you also set <property name="prefix" value="/WEB-INF/jsp/"></property> you need to put your viewpage.jsp and errorpage.jsp in /WEB-INF/jsp. I don't konw whether you create jsp directory in WEB-INF.
Sometimes controller can't find your jsp cause 404.
I create a project using your code,I work well.

Spring MVC - simple file upload HTTP Status 500 - Could not parse multipart servlet request

I'm starting learning the Spring MVC. Want to make web app with Excel file upload to database.
I'm starting with simple file upload and got problems at beginning.
My project made in Netbans using Maven and Tomcat 8.
I made simple example project with tutorial
https://saarapakarinen.wordpress.com/2015/01/11/building-a-basic-spring-3-web-project-netbeans-and-maven/
and it worked perfectly, but I wanted to change it a little to file upload based on official Spring help
http://docs.spring.io/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-multipart
I got opening form with file upload, when I select file and submit it i got an 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
How to solve this and where is error? It is error in my code or I'm missing somthing, or got wrong configuration?
I have one form on form.jsp file and one controller class HelloController why its not working?

do the changes as mentioned by #alan and also make following changes to your js function:
function SaveConversion() {
var params = $("#Conversion_form").serialize();
alert(params);
$.ajax({
method : "POST",
url : "saveConversion",
data : params, //this line is changed
success : function(result) {
alert(result);
$("#responseDiv").html(result);
messageDisplay();
return false;
}
})
}
the js function as per the question was sending only one parameter "param" which had value of serialized form value. After making above change it should be working. I have verified the same using network tab of the browser. You can see it for yourself if needed.

If you want to Spring to automatically bind the submitted parameters to a Conversion instance then you need to use the #ModelAttribute annotation in your method signature.
#RequestMapping("/saveConversion")
public ModelAndView saveConversion(#ModelAttribute Conversion conversion, Model model) throws ServletException, IOException, ParseException {
System.out.println("In saveConversion");
Boolean boolean1 = serviceDao.setConversion(conversion);
if (boolean1) {
model.addAttribute("conversionSaved", "Conversion saved successfully!");
} else {
model.addAttribute("conversionSaved", "Conversion Not saved!");
}
return new ModelAndView("setConversion");
}
http://docs.spring.io/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-ann-modelattrib-method-args
An #ModelAttribute on a method argument indicates the argument should
be retrieved from the model. If not present in the model, the argument
should be instantiated first and then added to the model. Once present
in the model, the argument’s fields should be populated from all
request parameters that have matching names. This is known as data
binding in Spring MVC, a very useful mechanism that saves you from
having to parse each form field individually.

JSP Expression Language Error

I have created a dynamic web module project usig STS and Spring MVC. The problem is I have add a string into a Model but it cannot be display on the JSP page using EL.
May I know what wrong with it?

I have JSTL.jar in my build path. There is warning message about the The tag handler class for "c:out" (org.apache.taglibs.standard.tag.rt.core.OutTag) was not found on the Java Build Path
Please help.
Thanks.

Download jstl-1.2.jar from the maven repo (http://repo1.maven.org/maven2/javax/servlet/jstl/1.2/).
Ensure that
the jar is available in WEB-INF\lib folder of your web application.

I would like to view your viewResolver configuration. Are you able to view the home page?? or there is 404 error?
If home.jsp is displaying properly then according to me the problem is in your jsp.
Look at the first line of the jsp where you have defined the page directive.
In that declaration remove the attribute isELIgnored="false" it is bydefault false everytime. So no need to define it explicitely.
I think if you remove that attribute. Your ${message} would display correctly.
Hope this helps you.
Cheers.
