There seems to be a annoyance in the clientlib NotificationListener
regarding the poll method in combination with MS Exchange.
The only way to subscribe to a folder when using polling is the following:
Credentials credentials = new UsernamePasswordCredentials("user",
"password");
NotificationListener nl = new NotificationListener( "myhost.mydomain.mytdl",
3500, "ourexchangehost.de", 443, Protocol.getProtocol("https"), credentials,
"/exchange/username", 60000, true );
Note that the poll interval is in milliseconds!! The javadocs are wrong.
nl.subscribe("Update", "/Kontakte", 1, 3600, 0, new Subscriber() {
public void notify(String uri, Map information) {
System.out.println("Event occured");
}
}, credentials);
So unfortunately you need to add the username to the repositoryDomain in
order to use event polling.
UDP based push should work fine.
