Java Forum / First Aid / September 2007adding graphics to my web app
I develop a small web application with NetBeans and Visual web pack. I need to add some dynamic 2D elements on my page. Which tehnology is the most suitable for that platform ? >I develop a small web application with NetBeans and Visual web pack. I need >to add some dynamic 2D elements on my page. Which tehnology is the most >suitable for that platform ? The web? Web friendly graphics are generally the sames types that the J2SE supports. Types JPEG, GIF and PNG. GIF format offers animation, but for anything more complex in terms of 'dynamic', you might need to use JavaScript to actively alter the page (e.g. to change images on mouse over). OTOH - I am not quite sure what you mean by 'dynamic 2D elements'.  SignatureAndrew Thompson http://www.athompson.info/andrew/ >>I develop a small web application with NetBeans and Visual web pack.

If the effects desired can be achieved using JS**, it would definitely be the best option. (I am guessing*) All the others would require a plug-in of some kind or other (*I am not immediately familiar with Dojo or Echo2). JavaFX is based around Swing, so that would come back to applets, I suppose, or at least something that requires the Java Plug-In. Applets are inherently problematic, and becoming more so by the month. For a stable, robust, easy access web site, I wold tend to avoid using applets at all. ** The slideshows and animated menus are easily doable in JS. Not sure about the text manipulation, check with the JS gurus on comp.lang.javascript.

For controls like text boxes, dropdowns, etc., consider Java Server Faces (JSF). The Dojo toolkit <http://www.dojotoolkit.org/> can manipulate text and shapes, and logos if they're graphics like PNG, SVG or JPG. It's a really good Javascript framework, from all accounts.

Good point. >The Dojo toolkit ><http://www.dojotoolkit.org/> >can manipulate text and shapes, and logos if they're graphics like PNG, SVG or >JPG. It's a really good Javascript framework, from all accounts. Huh.. Well I suppose that puts Dojo back 'into the mix'. >Cool "fisheye" demo: ><http://www.dojotoolkit.org/demos/fisheye-demo> I would like to say I looked at it. I *tried* to, but my phenomenally slow connection makes some JS based pages almost unworkable.

I use Firefox in Linux (Fedora Core 7), and once I unblock JS for the site it works fine here. I usually don't expect pathological behavior in Win/IE if it works in FF/Linux. Then again, JS is client-side software, and that leaves it up to MS how to implement it. As for speed of connection, that shouldn't matter too much, because the Dojo magic happens in the browser. One reason why I avoid JS myself is its lack of portability, that is to say, its dependence on the kindness of strangers. However, as Sun themselves have recognized, we need scripting, both client- and server-side. That's why I'm looking into Dojo and Rhino and Ruby myself. Coming as I do from the server-side viewpoint, though, I look at client-side behavior as the icing, server-side as the cake.

I have never investigated too deeply, but have trouble with many pages saying 'Done' loading when there is actually nothing on-screen, it seems after that (my guess) that a JS based call is made back to the server to - retrieve the actual content. This causes problems for my current WITUN, Google mail*, and many other pages. Even without any JS interaction, posting to the Sun forums can be a hassle through this connection, since by the time the 'Post Reply' page comes up - I have been 'timed out' and have to go through the damn log-in again! >One reason why I avoid JS myself is its lack of portability, that is to say, >its dependence on the kindness of strangers. It depends on the kindness of strangers to be *enabled*, but once that hurdle is past (passed?) it *can* be written to be completely X-browser - as long as a technique known as 'feature detection' is used. >However, as Sun themselves have recognized, we need scripting, both client- >and server-side.

(chuckle) I'm the kind of guy that will scrape off & eat the icing, but toss the cake to the dog. * Yes, yes. I feel entirely free to slag them, while making use of their services.

I ask that becasue NetBeans have a nice plugin for JMaki. Do you prefer Dojo under JMaki ? >I develop a small web application with NetBeans and Visual web pack.

Here are some approaches you can use. 1. dispense pre-built images. 2. compose images on the fly in the server with a PNG encoder or relative. See http://mindprod.com/jgloss/pngencoder.html 3. use an Applet or Java Web Start at the client end that reads raw binary data from the server and converts it into an image.

Look at the http://www.safari-fx.de/ I wish to be capable creating something like that but in a tehnology which I know (more or less). I mean: NetBeans, java, JS and dojo, JMaki as "compatible" tehnologies. >But I heard many negative opinions against applets in a battle applet vs JS >vs Flash ... >I don't know, I'm a newbie for a pretty long time and always will be :) Personally I hate JavaScript. It has ugly syntax. It is a primitive non-oo, language. It is buggy. It is has different bugs in every browser. I wish it would die. Ajax is an abomination. Applets are much better behaved. The problems with Applets are ensuring Java is properly installed, and that site administrators have not been spooked by Microsoft into blocking Applets with firewalls. The advantages of Flash are ease of installation, good penetration and tiny size. The run time is so small, I suspect it is a toy language, much like JavaScript. I like the idea of doing an entire project in one language. Then all team members can understand all the code and its interactions.

Applets are closer to me cause I have some knowledge from a developing desktop applications in java which consists 2D graphics elements. At this moment I have an "order" from a friend which demand a site for creating and ordering a stamps for his small bussines company, he demands something modern like this site: www.safari-fx.de I know how to create a "creating a stamp" part, but I'm not familiar with the "makeup" things and I have a feeling that flash programmers can do that easier and prettier:) >Applets are closer to me cause I have some knowledge from a developing >desktop applications in java which consists 2D graphics elements. At this >moment I have an "order" from a friend which demand a site for creating and >ordering a stamps for his small bussines company, he demands something >modern like this site: www.safari-fx.de that site uses Flash. It makes it pretty easy to have images dance about sprite-like. Flash was designed for precisely this sort of app. Perhaps you might proceed by learning flash, or by subcontracting that part out to an experienced flasher. I have never written a flash program myself, but I suspect even non-programmers can put together "flashy" presentations with it. The runtime is only about 3 meg. There can't be all that much too it.
