and managed bean class

package myjsftest;

import javax.faces.bean.managedbean;  @managedbean(name="hello")  public class hello {  public string getmessage() {        system.out.println("hello world function called");     return "www.javing.blogspot.com";   } }

i have verified via static output indeed managed bean class not returning output.how solve issue?

enclose outputtextcomponent inside h:form tag:

<h:form>    <h:outputtext value="#{hello.message}"/>  </h:form>

you can choose omit outputtext , place el expression in page , work fine:

#{hello.message}
