Hi,
Thanks for the quick answer.
I try this, but something strange is happening when I try to deploy
application (without the Tomcat restart).
I define ServletContextListener (create my implementation of this listener
and define this listener in web.xml). In method contextDestroyed I try to
shutdown all of the schedulers in following way:
ApplicationContext context = (ApplicationContext)
sce.getServletContext().getAttribute(WebApplicationContext.*
ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE*);
scheduler = (StdScheduler) context.getBean("scheduler");
cbcInterfaceScheduler.shutdown(*true*);
Boolean parameter means: wait for jobs to complete.
I follow the logs, destroy method is called and all schedulers are shutdown.
When I try to deploy same WAR file again, following error appears in
catalina log file:
Aug 13, 2010 12:22:54 PM org.apache.catalina.loader.WebappClassLoader
clearReferencesThreads
SEVERE: The web application [] appears to have started a thread named
[scheduler_Worker-8] but has failed to stop it. This is very likely to
create a memory leak.
Aug 13, 2010 12:22:54 PM org.apache.catalina.loader.WebappClassLoader
clearReferencesThreads
SEVERE: The web application [] appears to have started a thread named
[Thread-32] but has failed to stop it. This is very likely to create a
memory leak.
I also try to pause all jobs for scheduler and remove all jobs from
scheduler before I shutdown the scheduler, but I get the same error.
This is confusing for me because this is shown in log file when I try to
deploy application.
Could you give me some advice of how I can solve this?
Thanks in advance.
