Thanks for the info. Have just added a JIRA entry to cover this. http://nagoya.apache.org/jira/browse/CENTRAL-15 Steve.
-----Original Message----- From: David Leangen [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 20, 2004 12:23 PM To: [EMAIL PROTECTED] Subject: RE: Timeout problem Ok, thanks, Steve. I also just noticed that I need to start a new thread. http://avalon.apache.org/developing/framework.html Startable The Startable interface is used by any component that is constantly running for the duration of its life. The interface defines two methods: start and stop . Neither method has any parameters. The contract surrounding this interface is that the start method is called once after the component is fully initialized, and the stop method is called once before the component is disposed of. Neither method will be called more than once, and start will always be called before stop . Furthermore, the method must return, it can not go into a endless loop. From this follows that the component should create a thread and call the Thread.start() method inside this method to ctart the continous processing. The stop() method should interrupt the thread in a safe manner. This should be done by variables and the Thread.interrupt() method, slightly depending on how the thread is operating. Implications of using this interface require that the start and stop methods be conducted safely (unlike the Thread.stop method) and not render the system unstable. > -----Original Message----- > From: Stephen McConnell [mailto:[EMAIL PROTECTED] > Sent: July 20, 2004 19:19 > To: 'Avalon framework users'; [EMAIL PROTECTED] > Subject: RE: Timeout problem > > > > > First off - you can locate where the deployment timeout is occurring by > switching in -debug mode.
