WhoisJava v's C++

[TheMillionDollarMan]

Any thoughts?

The production environment is Unix using an oracle db. I am from a Windows to oracle world and I am looking for reasons as to why C++ would be faster than Java. There is not a lot of computations just a lot of transactions passing through.

Note its a web application and it all sits on the same machine ie webserver, db, corba ...

At this moment C++ is comparable in many cases regarding the speed with Java, VB, C#, J# etc... but there are some types of applications where C++ is faster visibly.
When you compare C++ with Java , the first the big difference is which kind of code is executed by the machine. Java have to translate using Java Virtual Machine before in order to execute. And more.

...which kind of code is executed by the machine...
Thanks for response.

ok.
This is a web to database application. Obviously there is some data manipulation, picking/putting messages to an Message Que, mapping, corba calls.

The key is to make this application ...."FAST"....and I'm looking for the fastest mix of technology.

I guess I'll just have to experiment and see.

it sounds like
Fortran, C++ then Java (depending on what you are using it for).

So the ideal web app would be
Data Access Fortran, Data Manipulation C++ and presentation in Java/jsp/javascript.
