[omniORB] using persistent reference with corbaloc

Tue Mar 22 15:51:39 GMT 2005

Hi Borg,

 That works fine when I have only the omniINSPOA
in the server implementation.

  When I have several POA in the server should I put
the POA name into URI ? can You give an example of URI
syntax when there is several POA  in the server ?
Or should be necessary use any command line argument
on  the client ?
   I apologize if that information has been already 
at omniORB documentation but I didnt find it.

Thank you one more time,

Frederico Faria
