Hello Brad,

The statement is true provided the JVM implementation is good and that the Java 
developers haven't done stupid things like use JNI or use VisualJ++.  That is 
no 
different from being able to migrate OS/400 code from CISC to RISC -- if the 
code still 
has observability.

All of the above Java programs are equally portable.  The problem is again in 
the JVM 
implementation (for Applets) or developer's choices (for Applications, 
Servlets, and 
Beans).  Java at least minimises the pain of porting unlike e-RPG which can't 
be ported 
at all.

A comparable Java application is unlikely run slower than VB unless you are 
using the 
Micros~1 JVM.  It is likely to run slower than C (or its incremental 
derivative) but the 
benefit IS better portability.  The only way Java is restricted to the Micros~1 
JVM is if 
VisualJ++ is used to effectively turn Java into Active-X objects or the Java 
code is 
simply a wrapper for a series of C DLLs invoked via JNI.

>But hey, it sold the product, didn't it?  

And exactly who's fault is that?  If purchasers exercised their own grey matter 
and 
didn't believe any marketing hype they'd all be running a certain 64-bit, 
object-based, 
integrated OS.

>And please don't ask us how to tell which JVM you have installed.    

String whichJVM = System.properties.getProperty("java.vendor");
String whichVersion = System.properties.getProperty("java.version");
String whichOS = System.properties.getProperty("os.name");
String whichOsVersion = System.properties.getProperty("os.version");

A piece of the proverbial .....

>*snicer*

snicker ... since Micros~1 haven't managed to kill Java they are attempting to 
make a 
hash of C.
