Runtime portability _does_ exist and the perfomance argument is old and outdated now, there's the hotspot compiler that can beat the lazy programmer (and aren't we all lazy?) and, although it's not java, you may note Raymond Chens' optimisation challenge[1] with C# and C++ and the results and discussion resulting. And of course there are other reasons aside from just the runtime portability to use Java; it's rich API, and so on. -- mic [1] http://blogs.msdn.com/ricom/archive/2005/05/10/416151.aspx _______________________________________________ Secure Coding mailing list (SC-L) SC-L@securecoding.org List information, subscriptions, etc - http://krvw.com/mailman/listinfo/sc-l List charter available at - http://www.securecoding.org/list/charter.php
