spring MVC <context:component-scan base-package="com.ginfo" /> - spring-mvc

Question

I am developing spring MVC using 3.0 annotation. Controller class is presented in com.ginfo package and here is the code.
HelloServletController.java
package com.ginfo;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
#Controller
public class HelloServletController {
#RequestMapping("/hello")
public ModelAndView helloWorld() {
String message = "HELLO SPRING MVC HOW R U";
return new ModelAndView("hellopage", "message", message);
}
}
And this is the content of my applicationContext.xml.
applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<context:component-scan base-package="com.ginfo" />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
I am getting error in the line <context:component-scan base-package="com.ginfo" />.
As a result HelloServletController is not executing.
And one more thing: I observed that when I created applicationContext.xml, I am not getting xsi:schemaLocation for /context and /spring-context-3.0.xsd like below:
<xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
Instead I am getting like this:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
</beans>
I did this in my eclipse for spring 8.6 and I added spring 3.0 Core libraries, spring 3.0 web libraries.
Please help me to resolve this issue.
Thank You

You are missing something in your applicationContext.xml, take a look at this (it's just an example i've just found in my workspace)
<?xml version="1.0" encoding="UTF-8"?>
<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-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
...
</beans>
Of course, you need to have spring-context-3 in your classpath
