easier and faster native code access is always wellcome. As someone said, it will not hurt cross-platform support as Java platform and average Java developer are matured enough that such a power will not be missused!]]> Fri, 17 Dec 2004 11:29:27 -0500 Fri, 17 Dec 2004 11:29:27 -0500 Fri, 17 Dec 2004 11:29:27 -0500 Dec 17, 2004 Mileta Cekovic 0 Not for performance (only) - for reusability http://www.theserverside.com/discussions/thread.tss?thread_id=30607 To me, Native access only should be used for hardware and OS spesific operations (like registry access), NOT for performance related operations.
That's all very well if you have the option to write everything in Java, but what...]]> Fri, 17 Dec 2004 11:28:16 -0500 Fri, 17 Dec 2004 11:28:16 -0500 Fri, 17 Dec 2004 11:28:16 -0500 Dec 17, 2004 A P 0 RE: Thankyou but no, thankyou. http://www.theserverside.com/discussions/thread.tss?thread_id=30607
