Using Abstract Class for dynamic tree

[jigneshdhua]

Hello,

I am currently trying to implement dynamic tree in richfaces which displays ldap users from server.

I want to call abstract method expand event of tree node. Implementation of that method is in different class.

Is it possible with richfaces?

Thanks in advance..

Unfortunatelly can't see the problem there.

Let me clear it first..

//User.java

public abstract class User
{

public abstract void showUser();

}
//UserDemo.java
public class UserDemo extends User
{
public void showUser()
{
//codding for adding user Group wise in rich:tree
}
}

Now, I want to call showUser() method by User instance, not by UserDemo instance..

Any help?

Thanks,
