What I have tried:

i'm trying to print a welcome message using spring mvc with maven
This is my spring-servlet.xml file

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http:www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd" >
<!-- enable component scan -->
<context:component-scan base-package="com.pack"/>
<!-- view resolver configuration -->
<bean	id="viewResolver"	
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		
		<property name="prefix"	value="/"	/>
		<property name="suffix"	value=".jsp" />
</bean>
</beans>

This is my Controller bean
@Controller
public class WelcomeController
{
@RequestMapping(value="/welcome",method=RequestMethod.GET)
public ModelAndView sayWelcome()
{
ModelAndView mav=new ModelAndView("welcome","msg","Welcome to spring mvc");
return mav;
}
}

This is my web.xml
