You used _this() in your example, but in omniidl2
generated .hh file it is just a substitute for _duplicate:
--------------
  Hello_ptr _this() { return Hello::_duplicate(this); }

Thank You very much, it worked.

^^^^^^^^^^^^^^^^^^^^^^^^^^^
It was our fault.

boa->obj_is_ready(a); is better :)

Maybe it could be useful to include this example into src/examples/
directory in omniORB distribution to avoid such questions as mine. I
asked it here just because I could not find by Altavista any example
which illustrates sequence<interface> usage.

Thank You once more.
