Hello<br><br>When connecting omniORB Naming Service through ORBexpress we must use the iiop:1.0 transport.<br><br>1.Using corbaloc:<br><br>When corbaloc object URLs are used, you will have to force OmniORB to
communicate via GIOP/IIOP version 1.0 since that is what ORBexpress
uses.<br>
<br>MyApp.exe&nbsp; -ORBInitRef NameService=corbaloc::iiop:1.0@localhost:2809/NameService<br><div>
<br>2.Using NameService<br><br>&nbsp; If you want to use ORBexpress Naming Service instead, here&#39;s an example:<br>
<br>
NameService=&quot;corbaloc:iiop:1.0@HostName:PortNumber/%B5Ad%B6ServerClassName%B5ServerInstanceName%B5POAName%B5ObjectId&quot;<br>
</div><br><br>Note:<br>&nbsp;<br>#define INCLUDE_CORBA_CORBALOC &nbsp; &nbsp;1<br><br><br>Thanks and Regards<br>suresh<br><br><br><br><br><br>
