Hi,

unfortunately it's not doable :( Grizzly comet implementation relies on
low-level Grizzly transport code, which, in case of Tomcat, is not used.
If you need container-independent solution for async HTTP request
processing, you'd probably want to check Servlet 3.0 and its
asynchronous capabilities.

Thanks.

WBR,
Alexey.
