This in turn seems to be because it looks for the current thread in threadsId and none have been put there. They're meant to be put there by the handle method, which I don't seem to be calling.

Let's see if we can make it work with the latest GlassFish build without
any needs to use the comet 1.5 implementation (which is targeted to
GlassFish v3 and embedded Grizzly impl. btw).
Now I need more information about when you are calling [
cometContext.addCometHandler(handler) ]. Calling addCometHandler() means
the continuation will be enabled on the current connection (most
probably a GET). You are getting the exception probably because your
context path is not mapping your registered CometContext. Mainly,
something like:
CometContext ctx = CometEngine.getEngine().register("/ABC");
*all* requests taking the form of:
/ABC/DEF
/ABC/comet
...
will enable the continuation (or asynchronous request processing
mechanism), hence you can call addCometHandler() on that connection. But
if you issue:
/AnotherPath/
and this path reach the Servlet where you are calling addCometHandler(),
you will get the exception listed above.
Hope that help.
Thanks
