Sorry to be slow on this.
I haven't found a working code example on the web.
<
http://n2.nabble.com/Filters-td2285491.html> is about as close as I
could find.
<
http://n2.nabble.com/ContainerResponseFilter-is-not-suitable-for-cleanup-job-td2312274.html>
is far from encouraging.
The javadoc for ContainerResponseFilter has:
A filter for filtering a response after the response is returned from a
resource class and before the response is written to the container.
The comment "before the response is written" implies (to me) that the
ContainerResponseFilter is called before the response is sent and/or
that the implementation must write out the response. Knowing some of
these details for how to do a cleanup following the transmission of a
response would be very useful. Also, are there other changes (web.xml?)
Does the @PreDestroy annotated method work?
Any help on this would be much appreciated.
Thanks
