I am struggling for last two days to expose a service using HttpInvokerServiceExporter. The error says Did not receive successful HTTP response The complete stack trace is below for details. The code is checked in Git repo. Link is - Github link

I have followed the documentation properly and have implemented all the steps. Below is the service interface:
package com.remoting;
public interface AccountService {
public int add(int a, int b);
}
Then the service implementation
package com.remoting;
public class AccountServiceImpl implements AccountService {
#Override
public int add(int a, int b) {
return a + b;
}
}
Then the web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">
<display-name>spring-remoting</display-name>
<!-- The front controller of this Spring Web application, responsible for
handling all application requests -->
<servlet>
<servlet-name>accountExporter</servlet-name>
<servlet-class>org.springframework.web.context.support.HttpRequestHandlerServlet</servlet-class>

</servlet>
<servlet-mapping>
<servlet-name>accountExporter</servlet-name>
<url-pattern>/AccountService</url-pattern>
</servlet-mapping>
</web-app>
Then the application beans. The application beans are placed in applicationContext.xml and is inside the /WEB-INF/classes directory:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
<bean id="accountService" class="com.remoting.AccountServiceImpl"></bean>
<bean name="accountExporter"
class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter">
<property name="service" ref="accountService" />
<property name="serviceInterface" value="com.remoting.AccountService" />
</bean>
<bean id="httpServer"
class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">
<property name="serviceUrl" value="http://localhost:8080/spring-remoting/AccountService"></property>
<property name="serviceInterface" value="com.remoting.AccountService"></property>
</bean>
</beans>
Now to invoke the service I have two jsp files and a helper class to load the beans and invoke the function:
index.jsp
<%# 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="process.jsp">
Enter Number:<input type="text" name="number" /> <input type="submit"
value="cube" />
</form>
</body>
</html>
process.jsp
<jsp:include page="index.jsp"></jsp:include>
<hr/>
<%#page import="com.remoting.ClientInvoker"%>
<%
int number=Integer.parseInt(request.getParameter("number"));
out.print("sum of "+number+" is: "+ClientInvoker.sum(number));
%>
Finally the ClientInvoker class
package com.remoting;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class ClientInvoker {
public static int sum(int number){
ApplicationContext context = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
AccountService service = (AccountService)context.getBean("httpServer");
return service.add(4, 4);
}
}
The applicationContext.xml is placed inside the /WEB-INF/classes directory.
Please let me know where I am going wrong.
I know it's an old question, but today I stumbled upon the same error occurring in HttpInvokerClientInterceptor. In my case, the cause was two different Java object versions used by the server and the client. As Spring's HTTP invoker uses Java object (de)serialisation, make sure that server and client are using the same version of objects/classes.
Referring to this question, it can also mean to just use the same serialVersionUID and different classes.

You can add / to
#RequestMapping(value="/LoginPage.html", method=RequestMethod.GET) like:
#RequestMapping(value= {"/", "/LoginPage.html"), method=RequestMethod.GET)
Or you can create a index page or welcome page in root path. What you met is just there is not a controller method which is mapped to /.
I am very much new to developing java applications using Spring framework. I have previously developed applications using MVC architecture but this Spring is really killing me.
I mean I can't a get a single new thing right in less than hour. Anyway, I am stuck in a very common problem while handling forms. I have tried for hours, searched the web for my problem and none of them have worked. Is it something to do with Netbeans? I don't know.

As you can see from stacktrace index.jsp can't map model attribute to form parameters.
This happans because you have index.jsp in your <welcome-file-list>. So index.jsp is loaded before controller and don't have access to model values.
To solve this problem you have to:
move your index.jsp file to WEB-INF/jsp folder;
change <welcome-file-list> to this:
<welcome-file-list>
<welcome-file></welcome-file>
</welcome-file-list>
or delete this tag at all.
add "/" to #RequestMapping in InsertController class.
So, now your controller will process request, add value to model and pass it to index.jsp.
Below I posted full code.
InsertController
import SpringApp.DAO.People;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import java.util.Map;
#Controller
#RequestMapping({"/", "/apptest.htm"})
/**
*
* #author ROHAN
*/
public class InsertController {
#RequestMapping(method = RequestMethod.GET)
public String viewRegistration(Map<String, Object> model) {
People userForm = new People();
model.put("userForm", userForm);
return "index";
}
#RequestMapping(method = RequestMethod.POST)
public String processRegistration(#ModelAttribute(value="userForm") People people,
Map<String, Object> model) {
model.put("name",people.getName());
model.put("city",people.getCity());
return "test";
}
}

it looks like your model attribute is not bind with request, make below change in your index.jsp
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<%# taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<form:form action="apptest.htm" modelAttribute="userForm" method="POST">
Name:<form:input path="name" />
<br>
Age:<form:input path="age" />
<br>
City:<form:input path="city" />
<br>
<input type="submit" value="Submit">
<br>
</form:form>
</body>
</html>
Now be sure that you have a test.jsp having modelAttribute of People bean otherwise it will again cause of error.
All,
A Spring newbie here.
I am trying to build a spring mvc(Sping 4.1.6 release) app. This app does not have a default landing page(like index.jsp, I have removed index.jsp from my app). This app will be called from another app by URL links or directly typing the path. My issue is I am not able to get this working. When I type localhost:8080/app/user.jsp(this is in WEB-INF/jsp folder) or localhost:8080/app/jsp/user.jsp(I would prefer not to use this path though).
Another question: I tweaked the app to have an index.jsp redirecting to user.jsp in the WEB-INF folder(not the WEB-INF/jsp) and the Controller #RequestMapping("/"), the user.jsp loads but the textbox is not displayed.

I am not sure what I am missing in both the scenarios. Thanks.
EDIT: The suggestion by minion solved my issue. Thanks.
There are couple of issues or changes you need to do. Here is the Gist of the issue :
Your spring servlet is mapped to / and the requested url is of the
pattern *.jsp. So it would never hit the controller that you wrote.
So change your controller to like one below.
#Controller
#RequestMapping("/user")
public class userController {
#RequestMapping(method = RequestMethod.GET)
public String initForm(Model model){
user user = new user();
model.addAttribute("user", user);
System.out.println("IIIIIIIIInside user Controller");
return "user";
}
Use the url localhost:8080/app/jsp/user to hit the controller.
}
I'm trying to create a simple Spring 3 application and have the following files. Please tell me the reason for this error
Below is my web.xml

Below is my dispatcher-servlet.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<property name="prefix" value="/" />
<property name="suffix" value=".jsp" />
</bean>
<bean name="/login" class="com.infy.controller.LoginController"/>
</beans>
This is the LoginController.java
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
#Controller
public class LoginController {
#RequestMapping(value="/login", method=RequestMethod.POST)
public ModelAndView loginAction(#ModelAttribute("loginBean")LoginBean bean){
return new ModelAndView("success", "success", "Successful Login");
}
}
And finally my LoginBean
public class LoginBean {
private String userName;
private String password;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
You'll have to have a ContextLoaderListener in your web.xml - It loads your configuration files.
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
You need to understand the difference between Web application context and root application context .
In the web MVC framework, each DispatcherServlet has its own WebApplicationContext, which
inherits all the beans already defined in the root WebApplicationContext. These inherited
beans defined can be overridden in the servlet-specific scope, and new scope-specific
beans can be defined local to a given servlet instance.
The dispatcher servlet's application context is a web application context which is only applicable for the Web classes . You cannot use these for your middle tier layers . These need a global app context using ContextLoaderListener .
Read the spring reference here for spring mvc .
And if you would like to use an existing context, rather than a new context which would be loaded from xml configuration by org.springframework.web.context.ContextLoaderListener,
then see -> https://stackoverflow.com/a/40694787/3004747
