Using @Component instead of declarative declaration?

Question

i was using declarative way to make beans the spring managed.It works fine. I am planning to go annotattion way now. I followed this Tutorial

What i did is

<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-2.5.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-2.5.xsd">


     <context:component-scan base-package="com" />

</beans>

And used the Component annotation

@Component
public class EmployeeServiceImpl implements EmployeeService {}

But when i start my web application i get below error

java.lang.ClassNotFoundException: javax.annotation.Nullable
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1680)
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1526)But when is start my web application i get  below error

UPDATE:- On google i found out that javax.annotation.Nullable can be found under jsr305-1.3.7.jar. But i think absence of jsr305-1.3.7.jar is not a problem as i could make it work in simple spring hello world project without the presence of jsr305-1.3.7.jar.So i think problem lies somewhere else.

i too downloaded that project it is based on spring-2.5.6.jar ... — Naren, Feb 28 '14 at 09:17

Add jsr305-1.3.7.jar to your classpath. You are getting the exception since the JVM is not able to find the required class

This is no where related to the spring jars. You need to ensure that you have all the required jars in the classpath – Keerthivasan Feb 28 '14 at 09:19
