* This test class contains three main tests:<br>
* 1. Tuscany is being used as a consumer of some non-Tuscany CORBA service<br>
* 2. Tuscany is being used as a service provider, which will be consumed by
* non-Tuscany CORBA client<br>
* 3. Tuscany is being used as a service provider, which will be consumed by
* Tuscany client<br>
* But that's not all, there are some other variations. Tuscany CORBA binding
* supports using Java interface generated by IDLJ, also it supports interfaces
* provided by user - I combined those cases in each test.<br>
