Sun Debuts JavaFX As Alternative To AJAX 441

Posted by kdawson from the YASL dept.

Does this really spell the end of AJAX? I sincerely hope so. Nothing built on Javascript will ever achieve the security, cross-platform reliability, and programmatic friendliness that Web 2.0 needs. Proprietary solutions and vendor lock-in are also dead ends. JavaFX has the potential to satisfy this opportunity even better than did Java over a decade ago. Along with AJAX, let's hope JavaFX also puts paid to Microsoft's viral Active-X and JScript, and, more importantly, that it really is a web scripting language that developers can grok."

    Applets, and Java in general, are notorious for long startup times.

    It has been found that people give a web site about 2 seconds to respond before they determine it is not going to load and surf away.

      Java 5 and (even more so) 6 have really helped curb the init time of applets. Plus on windows, IIRC it stays resident so after the first instantiation of the Java VM, load up times are very small. This is not including the time required to download the required classes for the applet, but it would probably be no worse than waiting for a heavy javascript laden page to load up.

        It's the first instantiation that matters.. Applets are so uncommon that the average user will only come across them once per reboot.

        Also, because of the most stupid thing Sun ever did, people tend to deliberately close the JVM after that first initiation. Why? Cause Sun puts a stupid little Java icon into the systray. It immediately draws attention to the fact that the JVM is in memory and people think they might get a speed boost or something by closing it. (Or something equally irrational that users think.) This was a pretty predictable result.. and the icon serves no purpose anyway, so why bother?

            More importantly, it's a change to their desktop which happens outside the browser window in response to going to a web page. Users don't really understand that it is the browser that spawned this.. they think that it was the web page that spawned this, and they understand that web pages shouldn't be able to put icons into their systray.

      On OS X, it's very fast even on my little G4. I believe that OS X pre-loads Java. On Windows, I know it can seem that way, but if parts were pre-loaded (or the whole thing kept in memory and just paged out when not in use) startup would be fast. If this became big (and lets hope, JS is terrible) then the browser would have a VERY good incentive to pre-load java and be ready to go. It wouldn't load up and unload all of Java each time you navigate pages.

        People may be annoyed by 2, 4 or even higher wait times, but they'll put up with them in the right circumstances without complaint.

        Showing people a blank screen, not so much. Show them a progress bar, and they might wait for it; especially if it contains something they need.

        The whole 'get it on the screen in 2 seconds or you've lost them' applies to online shopping, product reviews, forums, etc. But people are willing to wait 5-10 or even longer for their bank, their credit card, to file their taxes, to play a game, or to edit a spreadsheet. (As long as the 'start up time' is at START UP, and not after every click.)

        If 'web2.0 apps' like gmail took 5-10 seconds to start up, but didn't exhibit the html/javascript flakeyness that would be worth it. And a lot of the load time could be addressed with caching, and having the VM preloaded, if that was the only stumbling block, hell they really are more *application* than *webpage* -- with some browser support they could be ready to go in the background, selected like wii channels or something, for commonly visited 'sites'.

        AJAX is a mostly a train wreck on par with the spaghetti code that we inherited from the Basic/C/Cobol era. Html/javascript just wasn't designed for this sort of use. AJAX is like writing multithreaded real-time applications in Windows 3.0 or MacOS9 cooperative threading models... you can do it... and it can even mostly work most of the time if you don't bang on it too hard. But its never going to be great.

        asp.net was a decent move forward, as at least it mostly shielded the developer from the ajax mess. Unless you needed to do something .net didn't support, or worse when .net just didn't work and you had to dig into the javascript and html mess that your neat little .net app generates to find the problem and fix it.

        But we *really* need to see a good standards based framework on the browser side, that applications can be written against.

        Of course, we've always had Java and ActiveX. But Java was proprietary, and was hampered immensely by Microsofts attempts to discredit it, and embrace/extend/destroy it, including their own incompatible MSJVM, and "Visual J++" version of the language. Plus it was plagued by its own problems. Not to mention that the language itself I always found cumbersome. (I think Microsoft really did a good job with C# by comparison.) And ActiveX? Well, the less said about that plague on mankind the better. :)

        JavaFX, at first blush, looks like it might fit the bill.

          AJAX is an overused acronym. It doesn't do anything that you couldn't do with frames or popups anyways.

          The limitation was never that the XMLHttpRequest object wasn't around. The limitation was that you had to deal with the realities of sending your pages over modems, creating this pressure for dynamic pages, but older computers were too slow at processing JavaScript to allow you relief by moving much display logic into the client. You'd end up locking the whole browser.

          These problems are all dealt with now because of faster networks and faster computers. The tools in this area are just the same old shit with a shiny coat of paint for the most part.

    Did it occur to you that you're sounding exactly like the hype you're decrying?

    AJAX is a stupid name developed for the ole' hype machine (mostly to sell conferences and books, methinks) but the basic web technologies behind it are NOT THAT BAD. To use the example from the article, am I "tearing [my] hair out over as [I] attempt to get the JavaScript working in both Internet Explorer and Firefox?" Actually? No, I'm not. And I just implemented a Comet [wikipedia.org] library in both Javascript and Actionscript. About the most frustrating thing was the fact that Opera ignored the cache-disable commands when using XML.load in Flash. So I build a solution into the library. And if you think that's fun, wait until I detect Server Side Events in Opera and use XMLSockets in Actionscript!

    *shrug*

    Oh, and I had to dynamically patch Safari and Opera to add support for the toSource function. Easy as for(var i in object) pie.

    The problem with most "AJAX coders" is that they still think of Javascript as that cutesy language they used to do scrolling statusbar text with. But it simply isn't that bad. In fact, Javacript is a full-up, Object Oriented (or at least, OOP capable) langauge that fits the lightweight needs of the web browser perfectly. Java is a 600 pound gorilla that's better for designing heavyweight applications that are secure, robust, fast, and feature complete. The two target very different markets.

    As for JavaFX, there is (if you'll excuse the expression) "nothing to see here". It's just a Silverlight competitor. Which makes it just as questionable as the product against which it's competing. If you really want a replacement for XMLHttpRequest, use XMLSocket [devpro.it] instead,

      • Seems I confused you with my slightly sarcastic tone. "for(var i in object)" is a core part of Javascript and the way it works. That feature (and what it implies) are why it's so simple to fix different browsers to work like one another. If you don't know how to use it, you shouldn't be coding web apps.

        Also, OOP is not bolted on in Javascript. It's been there since nearly the beginning. It's just that 99% of web coders never actually learned how to code Javascript.

        How do you know JavaFX will be so bad when they have only announced it and haven't previewed it?

        I've been a Java programmer for about 11 years. In that time, I've explored the VM and libraries inside-out, upside-down, and sideways. The conclusion I've come to is that Java in the browser is a bad idea. At least in the form of the J2SE. If it had been developed more like a J2ME plugin with access to the DOM, it might have been a decent replacement for Javascript. But it wasn't developed that way, and now I think it's not in a very good position to compete in that space.

        This sounds like it is targeting more than just "fetch this list box dynamically" by trying to be a way to make web pages that are currently only realistically implementable by making the entire thing in Flash.

        You bring me requirements, and I'll show you the magic that modern web technology can perform. And it's only going to get better. My comments about Server Side Events and XMLSocket are meant to mention how much better it's going to get. SSE will effectively obsolete Comet-style requests, resulting in rich server "push" systems that can transmit nearly anything to the client on demand. No need to worry about different XMLHttpRequest implementations, it will all be automatic in the browser. Opera already supports this, and thanks to the magic of Javascript, it's easy to branch to code that makes use of it when available. Wrap it in your libraries, and you're ready. to. ROCK! :)

        Java has the ability to do static typing.

        Which is its strength as a platform, and its weakness as a scripting language. Don't get me wrong, the computer scientist in me wants to go with static typing. I love static typing. It makes all the bad problems go away. But the web coder in me knows that distributed document technology needs something more flexible. Dynamic typing as in Javascript is that flexibility.

What does Java provide that other languages don't? It looks like it has a client-side component. FTFA, "One of the knocks on AJAX applications, aside from browser compatibility, is that it requires a large amount of JavaScript to be sent over the wire; that script could have something malicious embedded in it.

    A demo of JavaFX (embedded in Java WebStart--yuck) can be found at http://blogs.sun.com/chrisoliver/ [sun.com] . Seeing as flash comes up instantly in browsers, even if it takes some time to download code, etc, and that web pages with ajax also render near instantly, I don't see how JavaFX is really going to appeal to end users. The JVM plugin still takes time to load on all browsers and platforms and is quite big. And on almost all browsers and platforms I've ever used, tends to lock up the browser for 10-20 seconds at a time. Further how will JavaFX integrate with HTML? Javascript?

    Flash and .NET don't have these problems, mainly because flash is a fraction of the size of the entire JVM adn runtime, and .NET is always loaded and ready to go on windows.

    Anyway, given the current state of Java technology in the browser, I don't see this as being any different from WebStart, which everyone loves to hate because it is so clunky.

    I dislike the idea of Silverlight entirely, particularly anything that relies on .NET (mono notwithstanding). I really want to like Java, I really do.
    • Agreed. How it interacts with HTML and JavaScript are going to be very important. AJAX fits nicely in there, and really is nothing new except the techniques. The HTML is still indexable, and the ad and tracking javascript is still there. With this, that may not all be true.

      Speak for yourself. I personally love Webstart technology. It's a beautiful solution to installing/launching applications in a cross-platform way. You just click, and it loads. No guarantees about the quality of content the developers package on the side, though. :-/ (The SpaceInvaders demo you pointed to being an obvious example.)

      JWS is pretty sweet for internal apps, though. I wrote a Swing client for a J2EE app for an internal group and folks were quite happy with the easy updates. They'd suggest a change and half an hour later I'd come buy their office, ask them to restart the app, and the new version would get downloaded and Bob's your uncle. Pretty sweet.

Basically, as a serious app developer, you probably have to partner with a wireless company.

    AJAX has given web-pages a new breath of life. Things like google-maps, netflix, etc. have definitely done things I wouldn't have thought possible before. And packages like RoR have managed to find ways to automatically generate most of the AJAX you need.

    I don't claim to be an AJAX expert, but it seems really good for the simple things you need to do. You can find 10 libraries now that give you collapsable boxes, drag-n-drop, etc. But it gets much more complicated if you want to do something not covered with these libraries.

    The big problem being that put very simply: HTML was not designed for full-fledged interfaces. Compare against a beautiful library like Cocoa, and it falls very very short. Which is fine. It's great for what it does.

    Java is many ways was supposed to fix this problem. A method to create interfaces that can be spread through web pages. But issues besides just speed have been a problem with Java. AWT was not great for making interfaces, and Swing isn't (IMHO) much better. I haven't tried SWT, but even Eclipse, its flagship, suffers from all types of interface issues (compare it against an IDE like XCode).

    I'm trying very hard not to be an Apple fanboi. I've used PCs for most of my life, and Linux for a good enough time (> 10 years). But I've seen enough interface libraries now (GTK+, KDE, Windows API, Javascript hacks, various ones using SDL, etc.) that I've seen both highlights and major downfalls from the different design paradigms used.

    One of the largest design issues I've seen comes from at the end of the day from the language itself. Part of A large part of Cocoa's beauty derives from Objective-C. It does things that c++ wouldn't dream of doing for speed reasons. Both Gtk+ and KDE try to replicate features already in Objective-C, but because they are non-native, they don't/can't do it as well. Which is not to say Objective-C is the end-all be-all language -- it's just great for interfaces.

    It's also something that from my personal experience Java can't do. So it's hard for me to imagine how using Java to make an interface for web pages will be a great advancement (again, I'm leaving speed issues alone -- this is a purely design argument). And maybe it will be better than AJAX, but that's not a great advancement .. a small increment without actually fixing any of the big issues.

    You know, the one thing I absolutely HATED about AJAX was how there was no delay when I loaded a page. For many moons, I have longed for the five second delay that a Java applet on a webpage incurs. I knew I was in for an interactive, highly responsive, good-looking user experience when my browser stumbled momentarily, as it loads the slim, petite Java runtime into the browser. It gave me plenty of time to prepare myself for the life-changing experience that ONLY an applet could deliver!

    But now, I can be happy once again. Thank you Sun! And with a hip name to go along with it, as well! JavaFX! I wonder if it is compatible with WinFX? Or how about ActiveX?

    So you acknowledge the presence of product solutions for ajax exist yet disqualify the possibility of using them because they are "dead ends"?

    there are no issues with javascript. cross site security simply demands you be resilient and durable and know when to fail user operations when they're asking for "funky" stuff, but that security was mandated at some level by traffic sniffing and packet generating long ago.

    Nothing built on Javascript will ever achieve the security, cross-platform reliability, and programmatic friendliness that Web 2.0 needs.

    Security - Javascript is NOT designed to secure a web app, security needs to happen on the server side, out of necessity!

    Cross-platform - I would argue that Javascript / ECMAScript, having been standardized and distributed with all major browsers for years, is arguably the MOST supported cross-platform programming language in the world. If a computer has a browser made in the last 5 years, it supports standardized ECMAScript. And what PC doesn't have a browser?

    The only incompatibilities I run into on a frequent basis are getting my scripts to create results that look the same across all browsers, and that's not Javascript's fault, it's CSS and browser support of CSS! If you have problems with the [i]functionality[/i] of Javascript, then you're probably not writing according to the well established standards, or worse yet, throwing together snippets of Javascript from all over the web like so many amatuers that give the language a bad rep.

    Proprietary solutions and vendor lock-in are also dead ends

    So you would use Sun's solution, rather than the well established internationally standardized ECMAScript?

    Programmatic friendlyness - Joel says it all here [joelonsoftware.com] Personally, I've programmed in dozens of languages, and few are as flexible and enjoyable as Javascript

    Javascript used to have the same status that Java applets and Flash still do, used predominantly for play things, small self-contained segments of the browser where you want to do something different. Javascript has risen above that. The world is finally realizing Javascript can be an integral part of an entire website, and that the website as a whole can be enhanced by Javascript and it's tight integration with other web standards.

    This article sounds like an attempt to rehype Java applets, which frankly, have not seen the advancement and acceptance that Javascript has over the years.

    Hellooooo everyone, the issue is not that historically the JVM takes forever to load or that Flash can be annoying. The key trend is that AJAX/Html are hitting a limit, which leads to all this recent energy about Flash/Flex as a better way to construct rich UIs, witness Microsoft's Silverlight.

    Now both Flash and Silverlight are totally proprietary. That's a huge problem. If one of them were to "win" and get a zillion developers ... well gee it seems historically this has led the winning vendor treat us all like crap. That's a real bummer when you have this expensive time investment in your website, but it's locked in to some vendor's intellectual property. The only other open rich alternative -- SVG + Javascript -- appears a bit dead.

    So what's neat about this announcement, is that it's a Flash workalike that's OPEN SOURCE. If it were to "win" ... that would be awesome. Even if the technology is just ok, the openness would make it worthwhile. Just think ... it could work properly on Linux and phones and what have you. This is very much like what happened with HTML originally. Just an ok spec, but the openness catalyzed all sorts of growth and competition.

    Another way this could work out is that it bluffs Adobe into opening up Flash, which I figure would be just as good an outcome. The key is to not be stuck developing your expensive web app, but with some vendor controlling the underlying technology.
