Acessing a managed bean from another managed bean

Hi,
I am new to jsf.My problem is I am not able to access a property value from one bean in another bean..can somebody please help.
I have an addressBook bean.I want to access this bean in my groups bean,where both my beans are session scoped. I Tried using @ManagedProperty but did not get a result.This is how i do it.

@ManagedBean
@SessionScoped
public class Groups extends GroupStore {
@ManagedProperty(value="#{addressBook}")
private AddressBook a;
public void setA(AddressBook a) {
this.a = a;
}


But it gives this eror .

Unable to create managed bean groups. The following problems were found: - Property addressBook for managed bean groups does not exist. Check that appropriate getter and/or setter methods exist.

Welcome to the Javaranch, Anu!

You're doing it right. Almost.

You apparently didn't publish a bean named "addressBook". If you're using the annotations on the AddressBook class, make sure that you have the "@ManagedBean" annotation set up correctly in AddressBook.java.

Thank you soo much for the reply.....ys now its working properly. I had done some mistakes in my web-config.xml Thank u:)
