No need to play word games. I mean in C/C++ you need to use #ifdef
__WIN32__ (or whatever) if you want your program to be portable. That
is what I mean by portable code. In contrast, Java world doesn't only
consist of classes and .jar files. Many operations (especially low
level ones, or those that need speed) are implemented in JNI, which
renders Java still C/C++ dependant, hence not easily portable.

Pretty much all the big finance companies in Wall Street (i.e. the
corporates that rule the world) develop in C++. Just to name a few, JP
Morgan, Goldman Sachs, Knight, Credit Suisse. They need speed for
transaction as they play their games in microseconds. Also many hedge
funds do.
I always wondered about this question too. I guess it is because it
gives the flavor of C++ to the lazy programmer who doesn't want to
learn a totally new syntax.
Culture - lot's of (good) frameworks for enterprise computing with good
documentation. Engineering
aproach to programming, thousands of reasons _not_ relevant outside the
business/enterprise world.
But that's where most of programmings lives. So, iff you educate for this
market, you better do it
in Java. I _never_ encountered a company doing in-house development in C++.
Also Java code
is slightly more portable
than C/C++.
I's not the code that's portable, it's the binaries. Try to use a library
_compiled_ with C++ compiler A
with a program compiled with compiler B on the same box! You can sell Java
class files and run them on
anything from Windows, Mac, Linux to TueUinx, Solaris (rip) and AS400 mainframes.
