Correctly shutting down a websocket handler
by Robin Anil
When a client disconnects, I see that onClose is not being fired. The only
way this seems to be firing if client sents a close frame.
Is there any way to detect disconnection and immediately close all the
opened resources.

This looks like a bug, I have filed https://issues.jboss.org/browse/UNDERTOW-1272.
I am a bit worried that it may cause minor compat problems, but if so they can be fixed by removing the trailing / from the template.

That I thing is correct because I just define two paths: '.../orders/' and '.../orders/{orderId}'. And the path '.../orders', that is not defined, respond 404. But when use this implementation:

That I thing is incorrect because there are just two paths again: '.../orders/{orderId}/items/' and '.../orders/{orderId}/items/{itemId}' but the curl with the exact URI use the second path template. Is this an issue or what I am doing wrong?

Dynamically add / remove servlets within a context in Undertow
by Martin Petzold
Dear Undertow community,
my environment is OSGi. I would like to run an embedded web server and
add / remove servlets on-the-fly. In Jetty this seem to be possible for
servlets contexts but not servlets within a context. It also seems to be
possible with some extra work with Jetty. I was wondering if Undertow
might be a bit more convenient for this case.
Is this possible with undertow and how could I do it?
Thanks and regards,
Martin
