So far I've looked at the possibilities with Java and JSP; I've downloaded KYLIX (C++, all I can do is look at it ) and it looks promising ( I guess); and I've noticed there's a .NET thing that I've not paid much attention to because, well, you know why.
I'm open to whatever will be here for the long haul and I don't want to expend great quantities of grey matter and end up in 3 years with a dud language. What would you do at this point in time ...Java, .NET or C++/#
It also depends on the business. Java has been used for financial applications and Wall Street type businesses for a while.
I suspect you'll start to see .net making inroads in places where Visual Basic is currently popular. Anybody who currently does VB, ASP and COM will soon be doing .net and C#.
Bottom line: if you can solve somebody's problem by implementing a web service of some sort, they're not going to care how you do it or what language you use. Start top-down. Figure out what a web service is. Figure out what kinds of problems it solves. Then worry about how to implement it.
Evolve too, and you will be always up-to-date ;-) Just start somewhere, that's the most important thing.
