Issue with WatchService in java 7
- by user972590
I'm using jdk7's WatchService API for monitoring the folder on file system.I'm sending a new file through
email to that folder, when the file comes into that folder i m triggering the ENTRY_CRATE option. its working fine.
But the issue is its generating two events of ENTRY_CREATE instead of one event which i'm invoking.
BELOW IS THE CODE:
Path dir = Paths.get(/var/mail);
WatchService watcher = dir.getFileSystem().newWatchService();
dir.register(watcher, StandardWatchEventKinds.ENTRY_CREATE);
System.out.println("waiting for new file");
WatchKey watckKey = watcher.take();
List<WatchEvent<?>> events = watckKey.pollEvents();
System.out.println(events.size());
for(WatchEvent<?> event : events){
if(event.kind() == StandardWatchEventKinds.ENTRY_CREATE){
String fileCreated=event.context().toString().trim();
}
}
In the above code I'm gettng the events size as 2.
Can any one please help me in finding out the reason why i'm getting two events.
