Question

I have developed a REST web application with Spring MVC and I can send JSON objects to a client.

I would like to construct a Javascript/AJAX client that connects to my web application but I don’t know how to send the first HTML page (using JSP).
I understand I should serve JSP pages with some embedded AJAX. This AJAX will send requests to my web services.

Update:
The requirement I am not able to achieve is to write the default URI (http://localhost:8084) in browser and see the HTML page I have written in JSP page (home.jsp).

My approach is following:

I have a Controller that sends the root JSP page

@Controller
public class SessionController {

    @RequestMapping(value="/", method=RequestMethod.GET)
    public String homeScreen(){
        return "home";
    }
}

But when I run the server I receive this warning

WARNING: No mapping found for HTTP request with URI [/home] in DispatcherServlet with name 'dispatcher'

and nothing is loaded in browser.

Here is my application-context file:

<?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:p="http://www.springframework.org/schema/p"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
       http://www.springframework.org/schema/aop

       http://www.springframework.org/schema/context       
       http://www.springframework.org/schema/context/spring-context-3.1.xsd">

    <context:component-scan base-package="com.powerelectronics.freesun.web" />

    <mvc:annotation-driven />

</beans>

And web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" 
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
         http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
    <session-config>
        <session-timeout>
            30
        </session-timeout>
    </session-config>
</web-app>

Is my approach correct? Am I wrong at any basic concept?
Can I modify something in my code to make it run?
I would like to see the first page loaded in browser and keep going in that direction.

Thanks in advance.

Answer 1

Finally I solve this only with configuring the dispatcher in web.xml on a different way.

First I added the view resolver to the servlet configuration file as David Riccitelli suggested me:

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
    p:prefix="/WEB-INF/jsp/" p:suffix=".jsp"/>

And then I configured the servlet mapping in web.xml:

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

That’s what I was looking for, and no extra configuration is needed.
Doing this I call my root URL http://localhost:8084 and I can see the home screen I have coded in home.jsp.

Thanks for your support and suggestions.
