Answer 1

I think you are missing the context loader listener(to pick your spring context file(s)).

Add this to your web.xml

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

You could also check out the Initial web configuration section @ http://static.springsource.org/spring/docs/2.0.x/reference/beans.html

Answer 2

You have both ContextLoaderServlet and DispatcherServlet set to load-on-startup = 1. That means either one of them could start first, and you need the ContextLoaderServlet to start first, since that's what creates the root WebApplicationContext that your error says is missing. So leave ContextLoaderServlet's load-on-startup at 1, and change the DispatcherServlet's to 2 or higher.

Actually, it's preferred to use ContextLoaderListener instead of the Servlet unless you're on a really old container where the Listener doesn't work properly.

Answer 3

Add following code in web.xml file, bcs it looks for contex to load so we have to declare it initially.

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/HelloWeb-servlet.xml</param-value>
    </context-param>

    <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
