Need ur suggestion: Comparison b/w VC++ and Java Interface Designing

AOA all,
I need some ideas and opinions from all of u.
Basically i am working on C++ application having C++ lib and Interface as well develop on VC++.
Now we want to make this application platform independent as some of our users might have Unix
and others.
So could all of u please give me idea if i develop interface in Java and using C++ libraries, wat
will be effect on performance and how enough Java interface designing is for desktop application as
compare to VC++ interface designing.
I need ur suggestion as soon as possible.
Thanx for ur ideas and help.

Best Regards
Atif

Usually the so-called performance issues do not exist as such in Java. It would at worst for a properly designed app as sowly as a VB app 2 years ago !
Now the worst can be done for our app to be unable to run properly ! what you should considere is the usual tips & tricks. To name a few :

Late initialization

Remove unecessary references

Object re-use

Avoid product (make your own Custom Component, instead)

Use proper Event handling

Reduce as much as possible too generic code (you asked for speed not for proper design --> interfaces are slow)

Avoid very large screens (like Tabbed panes)

You can also use the following references

Java Performance & Scalability - Volume 1 by Dov BULKA, ISBN 0-201-70429-3 @ Addison - Wesley

Java Performance Tuning by Jack SHIRAZI0-596-00015-4, @ O'Reilly

Hope this helps a bit.
Maybe comin with more specific question I will be able to able more ?

To interface between Java and C++, you'll need to read up on JNI (Java Native Interface) to make calls directly between Java and native code. You'll have to compile one version of your C++ code for each OS you plan to distribute it on.

On the other hand, you could make a distributed app and have a Java client talking to a C++ server through CORBA...
