'dispose' method of component

[Jeremy Quinn <je...@media.demon.co.uk>]

Hi All

I am working with the 'authentication-fw' in FlowScript, having added  
an authenticator that uses Hibernate. ie. My authentication pipeline is  
now a FlowScript which calls an internal pipeline to produce the  
authentication XML for the framework.

I am finding that the 'dispose' method of my Hibernate component (based  
on Hugo Burm's HibernateFactory) never gets called, until I quit Jetty,  
which is not what I expected.

This is my authenticator script:

// this function is called internally by the auth-fw,
// to get a pipeline to return an authentication XML stream
function authenticate () {
   var username = cocoon.parameters["user"];
   var password = cocoon.parameters["pass"];
   var factory =  
cocoon.getComponent(Packages.[long.path.deleted].PersistanceFactory.ROLE 
);
   var session = factory.createSession();
   try {
     var user = Packages.[long.path.deleted].UserPeer.login(session,  
username, password, null);
     if (user != null) cocoon.log.info ("Got User : " + user.email); //  
lubbly jubbly
     cocoon.sendPage ("screen/authenticate", {user: user}); // a  
JXTemplateGenerator pipeline
   } catch (e) {
     cocoon.log.error (e.getMessage ());
   } finally {        //catch (return) not working
     cocoon.log.info ("Disposing of Factory"); // I see this message
     cocoon.releaseComponent(factory); // I do not see the log message  
from the dispose method
   }
}

public class HibernateFactory
   extends AbstractLogEnabled
   implements PersistanceFactory, Configurable, Serviceable,  
Initializable, Disposable, ThreadSafe

The dispose method looks like this:

public final void dispose()  {
   //if (getLogger().isDebugEnabled()) getLogger().debug("Hibernate  
dispose called");
   // why oh why is this logger null!!!!
   System.out.println ("Hibernate dispose called"); // I never see this
   try {
     sf.close();
   } catch ( Exception e) {
     //if (getLogger().isErrorEnabled()) getLogger().error("Hibernate:"  
+ e.getMessage());
     System.out.println ("Hibernate:" + e.getMessage());
   }  finally {
     sf = null;
   }
   this.disposed = true;
   this.manager = null;
  }

I thought cocoon.releaseComponent(factory) should call the dispose  
method .....
Is there a method it will call if I provided one?

Thanks for any suggestions.

regards Jeremy

Thanks for your help, Giacomo.

Not on ThreadSafe components. The only one I know is a Recyclable 
component (which is a sub type of Poolable) but I don't think this is 
what you want your component to be.

Thanks for your clarification.

So is it possible to have a method called on my component when :

	cocoon.releaseComponent (component)

is called on it?

Thanks for your help

IIRC ThreadSafe components are disposed only when the ComponentManager 
is disposed (read shutdown of jetty). The counterpart interface of 
Disposable is Initializable which is called once during the life time of 
the component as with the Disposable.
