Chapter 6. Scenario: Synchronous stateful 279
options for accessing an EJB. Either or both may be implemented. The location
of the EJB in the environment is irrelevant.
6.2 Solution model using the ActiveX Bridge
Our solution model follows the pattern we have established, beginning with a
simple scenario to illustrate the processes and then describing the extended
scenario.
6.2.1 A solution to the problem
We begin with a stateful calculator written in Java which we have decided to
reuse in .NET. The creation of this calculator was covered earlier.
We will implement the ActiveX Bridge inside a separate COM component DLL,
written in C++, to handle all calls into the ActiveX Bridge.
In our simple scenario, the client will be a C# Windows Forms fat ...
