The remainder of the server source code sets an exception handler that prints an error message if anything goes wrong and terminates main (The closing curly brace at the start of this code fragment completes the try block we opened at the beginning of main)

This completes the server source code In this short example, most of the source code is boilerplate that you will find in every server In a more realistic application, most of the server source code consists of the actual operation implementations We are now ready to compile and link the server code The exact compile and link commands you use depend on your compiler and ORB For example, include paths differ from vendor to vendor, and you may have to add various preprocessor or compiler options However, the basic idea is the same for all ORBs: you compile the generated stub file (timeCcc), the generated skeleton file (timeScc), and the server source code you have written, which we assume is in the file myservercc Simple compilation commands could look like this:

Assuming that there are no errors, this produces three object files that we can link into an executable Again, the exact link command you use depends on your C++ compiler and ORB vendor Also, the name and location of the ORB run-time libraries you link with will differ for each vendor A simple link command is

Using Barcode creator for Java Control to generate, create DataMatrix image in Java applications.
Here, we assume that the ORB run-time library is called liborb Assuming that there are no errors, we now have a complete executable we can run from the command line On start-up, the server prints a reference to its Time object on stdout The server then waits indefinitely for client requests (To stop the server, we must kill it by sending it a signal)

The source code for the client also takes only a few lines of code:

Bar Code Printer In Java
Using Barcode creation for Java Control to generate, create bar code image in Java applications.
We must include the client-side header file, timehh, to make the IDL definitions available to the client application code The code then does a simple argument check and initializes the ORB run time with ORB_init:

Creating EAN-13 In Java
Using Barcode creator for Java Control to generate, create GS1 - 13 image in Java applications.
Note that we throw zero to implement a simple form of error handling An exception handler at the end of main ensures that the client exits with non-zero status if anything goes wrong The next few lines convert the command-line argument, which is expected to be a stringified reference to a Time object, back into an object reference:

// Destringify argv[1] CORBA::Object_var obj = orb->string_to_object(argv[1]); if (CORBA::is_nil(obj)) { cerr < "Nil Time reference" < endl; throw 0; }
This results in a reference to an object of type Object However, before the client can invoke an operation via the reference, it must down-cast the reference to the correct type, namely Time:
// Narrow Time_var tm = Time::_narrow(obj); if (CORBA::is_nil(tm)) { cerr < "Argument is not a Time reference" < endl; throw 0; }
The call to Time::_narrow has the same purpose as a C++ dynamic cast: it tests whether a reference is of the specified type If the reference has the specified type, _narrow returns a non-nil reference and nil otherwise
