WebSphere Enterprise JavaBeans as CORBA clients, the CORBA interfaces

The following example defines two CORBA interfaces. These interfaces, written in the CORBA interface-definition language (IDL), define methods to test the interoperability of CORBA data types between an enterprise bean running in the WebSphere Application Server and a CORBA server running on a third-party ORB. The Primitive interface defines the methods for testing the primitive CORBA data types, for example, characters, octets, integers, and floats. The Complex interface defines similar methods for the CORBA data types any and Object.

For each data type, there are three methods; each one returns the value in a different way. For example, the Primitive interface defines the following methods for a short integer:

...
interface Primitive
{
   const string serviceName = "primitive";

   const string testShortName = "short";
   short testShortIn(in short argin);
   void testShortOut(in short argin,
                     out short argout);
   void testShortInOut(inout short arginout);

   // Parallel methods for other data types
   ...
}
...
In the first method, the client sends the value in by using an in argument, and the server returns the result as the value of the method. In the second method, the client sends the value in the first argument, and the server returns it in by using the out argument.. In the third method, the client sends the value in by using an inout argument, which the server modifies to return the value. For each data type in each interface, a similar set of methods exists. The methods in the Complex interface are structured similarly.
