Subject [jira] Commented: (CAMEL-1098) multicast and file consumer using managed threads?
Date Fri, 05 Dec 2008 12:07:06 GMT

tim mcnamara commented on CAMEL-1098:
-------------------------------------

The unfortunate issue here is that there is another API (Timer) that  
provides the equivalent to ScheduledExecutorService.  This API is  
significantly different to the Java SE concurrent equivalents that  
would make the previous approach of proxying the interfaces very  
difficult.  So for now, it looks like there is no clean way to use  
ScheduledExecutorService implementations in a managed environment.

Moving forward, my suggestion would be for Camel to have it's own  
abstraction, similar to Spring's TaskExecutor, that would allow for  
the configuration of thread management whether running in a managed  
container or not.

JSR 236 offers hope for the future.

> Running in a server managed environment, it is preferable to use managed threads when
ever possible. Is it possible to have these components (and others that spawn threads) modified
to use Spring's TaskExecutor abstraction (a la JmsComponent). If this is the case, we could
configure the components to use the server's WorkManager API.
