Hi Lothar,
One possible approach would be to have a processor that receives the
notification and creates dynamically a route based on the notification
header to poll the directory.
Here is some pseudo code:
from(jms)
.process(new Processor() {
@Override
public void process(Exchange exchange) throws
Exception {
exchange.getContext().addRoutes(new RouteBuilder() {
public void configure() {
from("file://" + header + ? + sendEmptyMessageWhenIdle=true)
.to(somewhere)
}
}
})
The route could send an empty message when all the files are processed,
allowing you to detect that and stop it as shown here

HTH,
