It's 'ref="productManager" not 'value="productManager".
'ref' is used for beans.

another thing, i the jsp i had included the jstl, and messages.properties contains the below one.i call from the jsp using the messages.properties.

but the when i try to run, the tag is not showing.. it is diplaying like this.

???heading???

???greeting??? Tue Nov 27 10:33:12 SGT 2012


messages.properties (\HelloSpring\build\web\WEB-INF\classes)
----------------------------------------------------------------

title=SpringApp

heading=Hello :: SpringApp

greeting=Greetings, it is now

JSP code (hello.jsp)
---------

<%@ include file="/WEB-INF/jsp/include.jsp" %> 

<html>

    <head><title><fmt:message key="title"/> </title></head>

  <body>

    <h1>Hello - Spring Application</h1>

    <!-- <p>Greetings.it is now ${now}  </p> -->
    <!-- <p>Greetings.it is now <c:out value ="${now}" />  </p>  -->
    
    <h1><fmt:message key="heading"/></h1>

    <p><fmt:message key="greeting"/> <c:out value="${model.now}"/></p>

    <h3>Products</h3>

    <c:forEach items="${model.products}" var="prod">

      <c:out value="${prod.description}"/> <i>$<c:out value="${prod.price}"/></i><br><br>

    </c:forEach>

  
  </body>

</html>

First, have you defined your javax.servlet.jsp.jstl.fmt.localizationContext in the web.xml?
That tells the i18n tags what bundle to use.
Second, the bundle name should end '_<2char code>', so english would be 'messages_en.properties'.
You probably also want to define a fallback, javax.servlet.jsp.jstl.fmt.fallbackLocale.

i got the problem being resolved..

following are the step's i did it..

1) in the springapp-context.xml (dispacher ), i add the below

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

2) second, i placed the messages.properties file inside the /WEB-INF/classes. make sure that after clean and deploy the file stills exits.
