how to access registered bean in code

Hi, I need to access an "application" scoped bean defined in faces-config. I
digged in the forum and did found some answers to tihs, e.g.,
"FacesContext.getCurrentInstance().getApplication().getVariableResolver().resolveVariable(FacesContext.getCurrentInstance
(), "myBean1");",  

However this is deprecated version and when I am looking at JSF 1.2
documentation, I cannot figure out what is the equivalent way to do this...

Please could you give me some hints, many thanks!

Hi mate,

Use this for JSF 1.2 :-

FacesContext context = FacesContext.getCurrentInstance();
ELResolver resolver = context.getApplication().getELResolver();
MyBean myBean1 = (MyBean)
resolver.getValue(context.getELContext(), null, "myBean1");

Try this, it should work for any Expression but we just use it to fetch
managed bean instances.

  /**
   * @param managedBeanName
   * @return the current instance of the managed bean
   * @see FacesContext#getELContext
   * @see ELContext#getELResolver
   * @see ELResolver
   */
  public static Object getManagedBeanInstance(String managedBeanName) {
    Object object = null;
    FacesContext context = FacesContext.getCurrentInstance();
    if (context != null) {
      ELContext ec = context.getELContext();
      if (ec != null) {
        ELResolver er = ec.getELResolver();
        object = er.getValue(ec, null, managedBeanName);
      }
    }
    return object;
  }
