java - How to inject entire managed bean via @ManagedProperty annotation?

Question

I'm trying to inject entire JSF managed bean into another managed bean by means of @ManagedProperty annotation (very similar to Possible to inject @ManagedBean as a @ManagedProperty into @WebServlet?, but I'm injecting into a bean, not a servlet). This is what I'm doing:

@ManagedBean
public class Foo {
  @ManagedProperty(value = "#{bar}")
  private Bar bar;
}

@ManagedBean
public class Bar {
}

Doesn't work (JSF 2.0/Mojarra 2.0.3):

SEVERE: JSF will be unable to create managed bean foo when it is 
requested.  The following problems where found:
- Property bar for managed bean foo does not exist. Check that 
  appropriate getter and/or setter methods exist.

Is it possible at all or I need to do this injection programmatically via FacesContext?

Answer 1

You need to add setters and getters

@ManagedBean
public class Foo {
  @ManagedProperty(value = "#{bar}")
  private Bar bar;
  //add setters and getters for bar
  public Bar getBar(){
      return this.bar;
  }
  public void setBar(Bar bar){
      this.bar = bar;;
  }
}

When the FacesContext will resolve and inject dependencies it will use setters injection so appropriate setters/getters should be there.otherwise it won't find the property
