Oh it seems I have generated the stubs for JacORB with idlj Suns tool.
It seems I cant do it -- its the same when I try to generate Java
stubs from WSDL with tool from Axis and use them in CXF (this cannot
work too).

Thanks. I have generated my stubs with idlj tool from JDK 6.0. I
googled that I might have wrong bootclasspath - the ORB is usually
needed to be in the bootclasspath. So I have added JacORB to
bootclasspath and it does not work.
It seems it has nothing to do with Yoko. I created JacORB server and I
am trying to reach it with JacORB client with the same exception :-(
