Ok, I have removed oneway from IDL and encountered the problem.
Worse between two runs results were not the same.
One time request blocks, one time it raised CORBA BAD PARAM exception!

Finally I get the solution (these runs remembered me I had the same kind 
of behaviour between
JacORB and Mico) : Mico client has to be run with -ORBIIOPVersion 1.2 
option!
By default Mico use 1.0 protocol version.
While I used Mico on caller side and PolyORB on callee side there was no 
problem.
With the deferred callback pattern, Mico is called by PolyORB and it seems
that IIOP version matters in that case.
(By the time I had the problem with JacORB, I reported it on Mico list,
the maintener told me that it was a JacORB bug which ignored the IIOP 
version
used by the other ORB (Mico).
Maybe the same problem here with PolyORB?)

Yes the IOR I sent is corrupted.
Maybe an error during my copy/paste operation.
I tried po_catref on a new IOR, it works fine.


Again, thank you for your response which has triggered the solution!
:-)

Best regards,
