[NTLUG:Discuss] Need some inputs on porting.

[Vaidya, Harshal (Cognizant)]

Hi Stephen,

   The company has already invested heavily in the current application.
They've bought Solaris boxes, all the third party tools and have also
paid some company for the development and testing efforts. From last 4
years this application is serving them good. In fact most of the users
in the bank are now completely used to it. To move the application to
JAVA now, would involve a lot of cost. Moreover, the UI provided by JAVA
is pathetically slow. It just can't match the UI provided by C++ based
applications (I am talking about TrollTech, RogueWave etc). Since JAVA
UI is pathetic, one possible solution would be move it over the Web
rather than being a standalone App. This again brings in costs of
development of JSP/Servlets/EJB's, buying of Appication server licences.
Since the application to be ported is huge it surely dosent make sence
moving it to JAVA from a financial perspective. Porting would be a much
better and economical solution.

Thanks,
Harshal.

Hi Harshal.

I really have to ask,
for complete platform independence (for Linux, Solaris, 32bit, 64bit,
etc), I really have to ask, why not Java? Now a days, Java is just as
fast (and in many cases is faster) than C/C++. And it has all the
features you are looking for (at least as stated so far in this email).

Just wondering.

Regards,
Steve
