Subject Re: SOAP Performance against RMI
Date Sat, 27 Jan 2001 15:51:56 GMT
Hi Guys,

Yes, I agree with you. There is nothing worse than to be "fanatic" for some
specific kind of Technology. I must say I am a Forte Developer (Yes, one of
the last ones) and after working with several technologies during my life
(including Forte, Java and Microsoft), I got to a nice conclusion :
"Microsoft is Nice and reliable... for the NT world, Forte is nice and
reliable for the Enterprise environment... Java is realiable for
multiplatform environment..." Everithing is good in it own space and what it
was intended for.

SOAP is nice and easy for B2B applications. Because it uses HTTP as a
transport layer, it is platform independent. And because the Internet
popularity, B2B applications are focused on Internet. SOAP is a LIGHTWEIGHT
protocol to exchange information and because that there are a lot of
features missing in there.

CORBA or RMI are different things. They are intended to provide the enough
tools to built applications based on Distributed Computing concepts... and
THAT is the difference...

Regards...
