Right, those examples are for GlassFish v3. I need to backport them and
use the grizzly-compat module....you question inspired me to write a blog:

Does it work? Meaning you were able to run the example in v2?
Strange....it shouldn't work IMO.

Just to make sure I understood properly. You want to push data from,
let's say, an EJB or an external component, right? From an external
components, you just need to do:
CometContext ctx = CometEngine.getCometContext("YourContext");
ctx.notify(....)
The CometContext.notify will invoke the CometHandler.onEvent(), which
most probably have a reference to the HttpServletResponse. From that
object, you just need to flush what the external component/ejb have just
pushed.
Does that help?
