Java being superceded

Void

They're always saying **** like that.
He's probably referring to M$s new C# (pronounced C sharp) which is supposed to take the best of Java and the best of C and blah blah etc who knows. They said Java would kill C++ and it hasn't.
Bear in mind that if this lecturer in college was any good as a programmer he'd be off programming, and not lecturing where you only get a salary of about IR£20,000.

Java is SO nineties....

and lecturers dont ever have time to consult industry. and therefore earn more than programmers ever do.

java thing reeks of bs to me though.

Yes. I'm not a porgrammer but it's being suggested that XML will supercede Java, or (more specifically) a collection of XMl stylesheets (when they're developed)

I'm off to www.w3.org to try and find out.

Last time I looked XML and Java are two completly different things.

XML is just a coding structure for documents, where as Java is a programming language.

The only way a new language will supercede another is portability. Ease of use is all well and good but if you can't port your scripts to the new language easily people are going to stick with what they have (hence the reason COBOL is still around).

...or maybe they like teaching? A mate of mine quit a £100K a year job to do lecturing, I've just started a job in Maynooth college that pays less 'cause I'll get the chance to do a small bit of teaching. Money is nice, but it is not everything.

Draco

LoLth

OMG!!! YOU are going to be given access to unsullied minds??? What the F*** is the world coming to!!

nah, seriously though, a good point. Not everyone is in it just for the money. Some lecturers actually like teaching, some just want to have the time and grant for their research, some just don't want the ****e that comes with most other jobs. And don't forget teh extended holiday time!

I'm entiled to something like 35 days holidays. Bad part is that most have to be taken at particular times, but fu<k it, a month off in the summer? Great!

It may just, but that doesn't mean that it will achieve widespread use. Frankly I don't see the ideals of a year or two ago happening - those of a Java powered everything... from washing machine to wristwatch...

I would still avoid using Java on any web site I write.

Who knows? The language was originally developed for that purpose, and with the advent of jini, they're a hell of a lot closer to making it happen.

I'd disagree there. Use of servlets or jsp for front end combined with the Java Enterprise API is a pretty decent platform for n-tier development imho.

Well that'd be where you and I disagree then, - and that's fine. I'd still think Java is a little too slow, and there's little or nothing you can do on the web that you'd NEED Java for- i.e.: little or nothing you can do in Java that you couldn't do without it.

JSP has it's possibilities alright, but isn't it still a tad slower than pure ASP?

Slow for what exactly? Is this speaking from experience, or benchmarks or what?
Interpreting Java bytecode is not, and never will be, as fast as executing natively compiled code. However, People are starting to cop on to the fact that online compilers can produce code that is much more specifically optimized for the platform that it will be running on than a traditional offline native compiler, which can lead to your java code running as fast as (or, in theory, faster then) native code. So, the biggest remaining bottleneck is starting your JVM, which isn't an issue in a proper servlet setup ...

and there's little or nothing you can do on the web that you'd NEED Java for- i.e.: little or nothing you can do in Java that you couldn't do without it.

And to counter that brilliant argument, I could say "Well, there's little or nothing you can do with java's alternatives that you couldn't do with java", but it wouldn't be very convincing. I will point you again to the Enterprise APIs, and of course, Java's portability.

JSP has it's possibilities alright, but isn't it still a tad slower than pure ASP?

Recent comparisons I have seen show JSP to be faster. (not independent comparisons I must add, I'll look for something unbiased).

As for Java and speed...
IBM's Visual Age for Java has a big selling point that lets you compile your Java to native code for x86 and Alpha.
Haven't tried it out though....

Speaking from experience, and completely from a web developers point of view, java applets embedded in a web page are just too slow to render and execute through a browser to be completely viable.

Interpreting Java bytecode is not, and never will be, as fast as executing natively compiled code.

I'm not arguing with that, and I'm not drawing comparisons, I'm saying it's unacceptably slow- I didn't say anything is necessarily faster - like I said I'm talking from a web developers standpoint, so it's java on the web that concerns me, be it applets or servlets. Applets are too slow, servlets require extra training for our existing developers (and that training is unnecessary as theres nothing we can do with servlets that we cant do with existing ASP technology), so I'm saying I won't be implementing Java on any web sites soon - theres simply no call for it.

If JSP is faster then ASP then sure! it has potential!... but our developers know ASP inside out and there is little or no point in them wasting time learning JSP when there's little or nothing extra they can do in it that they couldn't previously do.

Bwaaah? You might want to get yourself a better machine.

I only find badly written applets slow. But that's just me. At least they tend to work under all browsers too. Remember when the net actually meant having a choice?

ecksor

Bard. Just a couple of points:
1) As I pointed out, Java can in fact be quite fast, and badly written java is the main reason for java being slow. I did say that interpreting java bytecode is inherently slow, but that is not the only way that java is executed ...
2) Your business reasons for not using Java weren't really what I was discussing (this is the programming board after all), I was more interested in discussing the it from a technology point of view. I use technologies all the time that I wouldn't if business reasons weren't an overriding factor.

As for why use java when you can use asp, and you know it/are experienced in it? Well, I use asp quite a bit, but I think that investigating the alternatives is a good idea in general, and as I've pointed out a few times already, the Enterprise APIs are actually very good (or the Java APIs in general for that matter) and worth investigating for a large scale web project.

What? I need something better than a PIII-500 with 128MB RAM, WinNT4.0 and IE5.1 to run Java applets smoothly?

"all browsers"?

HotJava, Netscape, IE and the new version of Opera. That may be 90-odd percent of the market but its not "all browsers". Besides that, a lot of people will turn support for Java off (as well as javascript/jscript). If you want to write a site that can be viewed and viewed easily by all potential viewers, it's simple - keep client side scripting to a minimum and don't use java applets.

But that's just my opinion of course.

And what a good opinion too, just last year here in the college, java support was switched off, which meant I couldn't get into any goood chat rooms. That ****ed me off, I'm not saying java is ****, I'm just saying Bard made a good point there.

Talliesin

Java will continue to be superceeded in some of the things it is currenly used for. It is already superceeded in some things (i.e. who in their right mings would use it for things that can now be done by dHTML, or perhaps Flash), but not others. More uses for Java will appear also (e.g. when it first came out you couldn't use it to write ActiveX controls like you can now).

Bard

I thought most web designers would know that you really have to design for (at least) last years browser, - last years technology (if not further back) to hit the widest and biggest target audience, and that this CAN be done without sacrificing functionality OR good design.

As well as that, it's naturally best to do as many things server-side as possible and avoid relying on the client's browser capabilities or those of its plugins, if any. This is not, therefore, a comment on JSP, but on Java applets.

My comment on JSP is that if we have a room full of developers who all know ASP inside out, (which is quite common in web design companies, including the one which I am employed in), and if and there's very little or nothing that JSP can do that ASP can't, I can see no reason to reccommend that time and money should go into training these developers to learn Java or JSP.

Sure, X_OR, I agree that investigating alternative avenues and technologies is always a good idea, but Java as a technology just doesn't look as appealing to me, these days, as it used to. I'd love to be able to explain why in more detail, but I can't really- it's just a non-starter as far as I'm concerned. I've read up on it, - believe me! - and yes, it is an excellent technology with a lot of promise, but until the penetration is such that the likelihood of a person viewing my web page being able to view any java applets I want to throw at them, and view them sufficiently quickly, increases significantly, I won't be using this technology.

I think I've said my piece

Who said anything about applets?

This isn't a thread about applets.
This isn't a thread about JSP.

If the thread concerns Java, then discussion on applets IS relevant as far as I'm concerned. I'm a web developer, and the only way I've ever used Java thus far is naturally in an applet embedded in a web page, so I stand over my words.

Well, thats one convincing argument you got there.

Well, that's fair enough, but I agree with what Talliesin said on that issue.

As have I, probably nothing more for either of us to say here.

You haven't been paying attention. All of my talk on Java and web development was focused on server side technologies. Fair enough, you use asp, so do I for most things but to say "I'm a web developer, and the only way I've ever used Java thus far is naturally in an applet embedded in a web page" is ignoring all of it's other uses in the area you claim to be expert in.
