I've the following error. I don't understand why.
[INFO] javax.servlet.UnavailableException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping': Initialization of bean failed; nested exception is java.lang.IllegalStateException: Cannot map handler [mapController] to URL path [/map.jsp]: There is already handler [com.application.myGoogleAppEngine.controller.MapController#978068] mapped.
Do you have any solutions ?

Try it with the following changes
In your XML, add annotation-driven element:
<context:component-scan base-package="com.application.myGoogleAppEngine.controller" />
<mvc:annotation-driven />
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/pages/" />
<property name="suffix" value=".jsp" />
</bean>
In web.xml, change the url pattern
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
So, you can use your Controllers like that:
#Controller
#RequestMapping("/map")
public class MapController {
...
}

You either need to change your url from basepath/home.do to basepath/home or change mapping from /home to /home.do. That should work.

Please check import

I tried changing it to import org.springframework.web.servlet.ModelAndView;
and it worked for me.
When I add an autowire into my controller I get the following exception:
No qualifying bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
I am not sure how to solve this any suggestions please?
I was wondering whether or not it was something to do with my component scan in the application context?

Can anyone help me to find the reason of this error i already tried multiple solutions as they have the same error but none worked for me its the first time i do Spring from scratch :(..
WARNING: No mapping found for HTTP request with URI [/SpringMVCTutorial/] in DispatcherServlet with name 'dispatcher'.......
Followed by error 404 on the browser.
I think you have two problems here:
First, you need to use <mvc:annotation-driven /> to enable annotation based controller.
Second, it seems to me that you want to have a default page when typing the context root only.
In this case, you need to add mapping like this:
<mvc:view-controller path="/" view-name="index.htm"/>
Or change <prop key="index.htm">indexController</prop> to
<prop key="/">indexController</prop>
This question already has answers here:
Why does Spring MVC respond with a 404 and report "No mapping found for HTTP request with URI [...] in DispatcherServlet"?

Please, help to find my mistakes.
I've got error "WARN : org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [] in DispatcherServlet with name 'spring'"

}
It seem that the package that contains controllers is not scan by the application.
Uncomment that line in spring-servlet.xml :
<context:component-scan base-package="by.rubanovich" />
EDIT
Add this to you web.xml
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
And correct this listener :
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
in my case i have more than one Controller and I got this same problem. After removing a class level request mapping for the controller from where the issue arised solved the problem for me.
I think that you've a problem on your url. Because your controller is configured to manage requests by #RequestMapping("/index")
So if your want to access your project /TestJavaMvcWeb/ you have to:
change your RequestMapping("/index") to RequestMapping("/") or
access your url by /TestJavaMvcWeb/index
