Subject Re: Jetty Continuations in CXF
Date Fri, 14 Nov 2008 10:24:00 GMT
We may want the continuation support to work in both case.  This is
the case in jetty, and we may want to mimic the same kind of behavior
in case some transports do not support continuations.
In such a case, the continuation simply blocks and waits for a call to
resume(), in which case, the thread is unlocked and the processing is
resumed.
