Conveniently Declaring Compile-Time Strings in C++

...h most of what is written above, I would like to refine the "how to start" ideas a bit.
My suggestion to you is to never ever program directly to EJB interfaces within your code. Always use a regular, business-oriented interface, program to it (meaning, have your code call methods on the business-o...
