How to add dispatcherServlet and other Spring Bean configuration in Web.xml

Question

I am working on the this example. I was receiving the same error message. I have modified the code as mentioned the answer, I am not receiving the below error message anymore:

Caused by: java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/applicationContext.xml]

However, I am not able to redirect to the jsp. Please find code details below:

You are trying to load a jsp with name "home", but you don't have this page. You have only "hello" jsp

Change this

@RequestMapping("/")
public String home() {
    return "Home";
}

On this

@RequestMapping("/")
public String home() {
    return "Hello";
}

Also change your path to the configuration file

Change this

<servlet>
    <servlet-name>offers</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value> 
        classpath:org/exSpringJDBC/config/exSpringDao.xml
    </param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

On this

<servlet>
    <servlet-name>offers</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/offers-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

Thanks 3asyPe. But I am still receiving the same error message. I have edited the Controller now. — Wolfgang, Jul 26 '20 at 13:47
