Problem setting DefaultQoS with Notification Service

Hello everyone,

previously I had problems setting QoS-parametres - that is now passed.
After trying to circumvent the problem by using java to call
EventChannelFactory:create_channel (which didn't succeed by some weird
problem with JacORB's idl-compiler), I used cut & paste -method from the
sources and after reading little bit manuals and tutorials I could
construct a kind of working record which was accepted by
EventChannelFactory:create_channel. Jesh! There only seems to be problem
with JacORB's understanding of IORs with "wstring inside Anys" - even after
a patch to recent JacORB 1.3.21. This is off topic but just to tell the
status that no one is going to bother with the previous problem.
