Hi Paul, thanks for your pointers, I seem to have solved it...
Firstly, I was trying to increase the logging level and was failing
miserably, so download the source code (should have done this ages ago)
and ended up stepping through the creation of my objects.
A few things are going on.
Firstly I seemed to have been using the wrong ManagedBean annotation
javax.faces.jsf instead of javax.annotation - I'm sure I had tried the
latter originally with no luck hence the switch. Also did 1.1.5 change
anything as I recently updated the jersey libs on my glassfish box.
Secondly if I include the constructor, then using @ManagedBean cause an
error on deployment because cdi can't find a default constructor. Using
@ApplicationScope doesn't generate an error but doesn't inject anything.
Finally, removing the constructor and using either annotation does
indeed work as expected - Again thought I had tried this combination
before...
Either way thanks for your pointers
