If you try to connect to jndi lookup service and get the connection refuse message to localhost:3700 , but you really like to try connect to host 172.19.100.60:12074 , you need to set java system properties like follow -Dorg.omg.CORBA.ORBInitialHost=172.19.100.60 -Dorg.omg.CORBA.ORBInitialPort=12074
