[OS-webwork] How to use the ComponentManager

[Christian Meunier]

Hi all, i am trying to use the ComponentManager class to initialize a 
component in a servelt filter as follow :

public class HibernateFilter implements Filter
{
   private Log log = LogFactory.getLog(this.getClass());
   private ComponentManager componentManager;
   private PersistenceManager persistenceManager;
   public void init(FilterConfig filterConfig) throws ServletException
   {
       ComponentManager componentManager = (ComponentManager) 
filterConfig.getServletContext().getAttribute("DefaultComponentManager");
       componentManager.initializeObject(persistenceManager);
   }
   
   ......

}

And i got :

java.lang.NullPointerException
        at 
com.opensymphony.xwork.interceptor.component.DefaultComponentManager.loadResource(DefaultComponentManager.java:122)
        at 
com.opensymphony.xwork.interceptor.component.DefaultComponentManager.initializeObject(DefaultComponentManager.java:73)
I obviously miss something but what ?

Thanks in advance
Christian Meunier
