Spring: message, Message not found by code for locale 'en_US'

This is what I added to my spring-servlet.xml

<bean id="messageSource"
        class="org.springframework.context.support.ResourceBundleMessageSource">
        <property name="basename" value="classpath:application"/>
    </bean>

      

        
        
        
      

    

and my application.properties file is inside src / main / resources folder but I am getting this exception

SEVERE: Servlet.service() for servlet [MVC-Dispatcher] in context with path [/MVCLayer] threw exception [javax.servlet.ServletException: javax.servlet.jsp.JspTagException: No message found under code 'Login_Username' for locale 'en_US'.] with root cause
javax.servlet.jsp.JspTagException: No message found under code 'Login_Username' for locale 'en_US'.
    at org.springframework.web.servlet.tags.MessageTag.doEndTag(MessageTag.java:200)

      

        
        
        
      

    

Please help what is wrong with the config
