Spring MVC Http Status 404

Question

I'm trying to create my first Spring MVC application but when i tried to run project on server(Tomcat 7) fault appears in my browser Http Status 404 (here is link on the fault screen). Could you tell me where is the mistake? You can see the most important files below. Here is the link for the complete project https://github.com/tommiCZE/SpringMVCSampleApp/tree/master/SpringMVCSampleApp.

Answer 1

First problem: your application loads the view-resolver-servlet.xml configuration file twice, once by the ContextLoaderListener and once by the DispatcherServlet. You don't want this as you'll have a bunch of duplicate beans. You don't currently need your ContextLoaderListener. Get rid of it.

Second problem: you're missing

<mvc:annotation-driven />

from that context configuration (with the appropriate namespace declarations). Without it, the Spring MVC stack will not register your @Controller beans as handlers. Your

<context:component-scan ... /> 

only scans for beans and adds any it finds to the context.

Third problem: you're sending a request to

/SpringMVCSampleApp

when you don't have any handler methods to handle that path. Add one. Or add a <welcome-file> to your deployment descriptor, ie. the web.xml.

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

assuming the index.jsp is at the root of the WAR, ie. outside WEB-INF.
