You will find writing CORBA 2.2 clients problematic. Although it is correct that there is a CORBA client in the bank example, this client will only run on top of VisiBroker for Java 4.x. It is difficult to support VisiBroker for Java 3.x clients because they do not have OBV support necessary for handling many common Java data structures. The CorbaBankClient uses the CORBA naming service APIs to resolve the EJB home and then uses CORBA-style narrows to obtain a CORBA objref. However, you still have to use RMI-style method signatures to access the home and remote interfaces.
