Is there any way for the server to recognize the changes without restarting after a properties file updated? Because it causes Java.lang.OutOfMemoryError: PermGen space after the second restart.
The properties file is under Web-Inf folder.
Cheers…
There is no direct way!
The Tomcat Webapp Classloader caches every resource which has been loaded by it. A change won’t be visible unless you restart the context. There is no API clearing that cache. All you can do is access that map via reflection and call the clear method. All resources will be re-read from disk on request.
Clear this HashMap and your are done! The file monitor won’t really help since you have a custom classloader.
