Or if you want to access another managed bean at "runtime" so to speak 
you can use a method something like this:

  public static Object resolveExpression(FacesContext ctx, String 
expression)
  {
    Application app = ctx.getApplication();
    ValueBinding bind = app.createValueBinding(expression);
    return bind.getValue(ctx);
  }

Hi,

Why not simply refer to the other bean using Dependency Injection
through the JSF Managed Bean mechanism?

For example,

<managed-bean>
<managed-bean-name>yourInitialBean</managed-bean-name>
<managed-bean-class>com.whatever.you.want.YourInitialBean</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>otherManagedBean</property-name>
<value>#{otherManagedBean}</value>
</managed-property>
</managed-bean>

Quique.
