Hello Everyone,
in my web app I use Java 7 directory watcher feature.
When the final war file is placed into Webapps folder and Tomcat is started,
it freezes as it waits forever for any directory changes (the app is loaded
on tomcat startup).
I use the following workaround - calling my watcher code in a new Thread (in
the context init phase).
It does the job, but I am not sure if this is the best solution. Couldn't be
the same effect achieved using specific tomcat options?
What do you think?
Thanks, Jan
