Is JavaFX 1.0 Release Still GPL'd?

I asked this question a while back, and have still
not heard back.
Will the JavaFX 1.0 Release be GPL'd?
This is an important question for us.
Can anyone give us an answer.

Great! I think the serves are little loaded though right now. I have cable internet and the applets are taking forever to load. I think I'll come back later today. Maybe this means lots of java developers are interested!

JavaFX 2.2 release date??

Can somebody let me know when JavaFX 2.2 is going to be released?
Also it shall be helpful if somebody can state the modifications (at high-level) in JavaFX 2.2 from 2.1.

Can somebody let me know when JavaFX 2.2 is going to be released? 2.2 is feature complete, there are still a bunch of QA to be done and issues which need to be fixed.
Roadmap would put it going GA a couple of months out (by non-expert, outsider, eyeball estimate).

Also it shall be helpful if somebody can state the modifications (at high-level) in JavaFX 2.2 from 2.1.More low level than high level, but I'll let you work out the high level things from the list of features which have been implemented (closed as fixed) for 2.2 from the (public) jira.

JavaFX 2.1 released!

Nobody mentioned it yet!?
JavaFX 2.1 GA is released :)
http://www.oracle.com/technetwork/java/javafx/downloads/index.html
Does anybody know if it runs under Mac OS 10.6 (Snow Leopard) ? I heard a long time ago, that it will only run with Lion.

If anyone have such problem, please, mark it in this thread...This does not really help much.
It is much more efficient to update JIRA and work with JavaFX developers to understand the issue.
Have you tried "Open with" option?Yes, I tried to use all java.exe I have, but... Remember that launching jar means that command need to be
java -jar a.jar
When you select java.exe in open with menu it will not work as result command is
java a.jar
(you can change registry manually or create wrapper file that adds -jar on the command line)
Both these issues ( JavaFX applets launch in Chrome has bad UX && JNLP-start consumes large amount of time ) tracked in JIRA for many months.
Just now jira is unplugged, and I can't point certain numbers.JIRA is back. Please share links to the issues. I suspect that Chrome issue you are referring to is due to Chrome blocking native plugins?
I wonder if we have enough details on performance issue (like Process Monitor and detailed trace logs, any measurements, etc.).
I do not see extremely bad performance myself.

JavaFX 2.1 release date?

Does anybody know, when JavaFX 2.1 GA for Windows will be released?

From what I've picked up, it all seems to point out to a release this month.

1.0.3.101.gbfa97dfe Release: Still No Images Behind Proxy

I've searched for an update to this issue, but there doesn't seem to be a verified solution beyond downgrading the app.The standing issue is that I'm unable to see any images behind my work proxy. We have both an http and and https prox. Neither require a username or password login. Prior to the 1.0.3 update I was able to see all album and user images. my prefs look like this:app.autostart-banner-seen=true
core.flash_version=16
autologin.username="someuser"
network.proxy.addr="http.proxy.somecompany.com:1234@https"
autologin.blob="a blob"
autologin.canonical_username="someuser"
language="en"
network.proxy.mode=2
core.clock_delta=0 I've tried installing and uninstalling Spotify. Mostly I just want to verify that this is a known issue and it's being worked on.

Over 8 months since this thread was opened. There are NUMEROUS threads on this issue and none have a community advocating giving any indication that Spotify even acknowledges this is an issue. It's nearly impossible to debug this problem since all the code in the App Package is obfuscated. Here's what I know:If I disconnect from the proxy and remove any reference to the proxy I get picturesAny pictures that are downloaded while "off proxy" are cached and they show up normally in the app once I'm back on the proxyRemoving network.proxy.addr from the "prefs" file but leaving "network.proxy.mode=2" while off proxy will prevent me from downloading imagesChanging "network.proxy.mode=2" to 1 while off proxy allows me to download imagesI don't get any meaningful errors in my console, but from time to time "Spotify Helper" shows upHonestly, none of should be surprising. I can't do any more troubleshooting on my end. Was hoping a Community Advocate (familiar with the issue) would weigh in.

How to run JavaFX jar with JRE7 on MAC OS Lion 10.7.5 ?

     </target> When I am trying to run that JavaFX application jar on MAC OS Lion 10.7.5 using
java -jar application.jar
It always shows a dialog "The application require a newer version of Java Run-time" with download link. Even I have downloaded and successfully installed it on my MAC machine but it still shows me the same window.
java -version is always point to 1.6.
Then I searched for Java Preferences to point the current JRE 1.7 but I could find Java Preferences at Applications -> Utilities -> Java -> Java Preferences.
I would like to know -- how to run JavaFX jar with JRE7 on MAC OS Lion 10.7.5? Is their any other way to run the JavaFX application JAR with JRE7?

Do I need to download the whole JAVA 1.7 on MAC to run the JAR? No
Can not I run the Jar file with Jre7?Yes, you can.
This may be because I have downloaded the JRE 1.7Yep, that's correct, the java_home command only works for jdk's - sorry for the confusion.
For jre7+ versions, only a single Oracle jre version is allowed to be installed on the machine at a time - making a tool like java_home redundant for jre checking.
Weirdly, jre7u10 does not supplant the Apple Java on the command line path by default. If you just type java -v, then the Apple java version will displayed if you have an old Java 6 from Apple and a new Oracle jre7+.
The Oracle jre is always located under (also somewhat strangely):
/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/javaTo test jar launching, I used the willow JavaFX browser pre-release jar available here:
http://code.google.com/p/willow-browser/downloads/detail?name=Willow-0.1-prerelease.jar
Then I launched the jar from the command line using:
/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -jar Willow-0.1-prerelease.jar The JavaFX jar ran fine on jre7 with the above machine.
The test machine was running Mac OS X 8 with Oracle jre7u10 installed as well as the Apple Java 6 runtime, but no Oracle jdk7+ installed.

JavaFX Window Icon

Hi
I saw in the release notes of JavaFX 1.0 (http://java.sun.com/javafx/1/reference/releasenotes/javafx-sdk-release-notes.html) that setting icons for the Stage class does not work.
In my application which uses JavaFX 1.1 I also encountered this problem. Is this feature supposed to work in later versions of JavaFX or is it still a bug?
Here's the snippet of the code that I used to set the icon:
icons: [
Image { url: "{__DIR__}my-logo-16.gif" }
]

I also tried with png file with the same result ...
no icon changed in maximized, normal and minimized states.
and to make sure I didn't miss the image location, or the format is readable by JavaFx,
I add the same image to the Scene
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.HBox;
import javafx.scene.Scene;
import javafx.scene.text.Font;
import javafx.scene.text.Text;

JavaFX Mobile EA on Window Mobile 6.1 cannot show chinese correctly

Text{content: "测试" }, it is shown well in the JavaFX Desktop or applet. but it is garbled on JavaFX real device(HTC Touch Diamond 2 Window Mobile 6.1 professional)
I also try the new String("测试".getBytes(), "UTF-8") even "\u6D4B\u8BD5", nothing can be working well.
Anyone can help us on the garbled issue? we are really appreciated him, now we have tried any way and where should we go?
Thank you very much

the Character is not equals charIt should be, but it seems we don't have total symmetry of types yet. See [finish primitive-sequence to primitive-array conversions|http://javafx-jira.kenai.com/browse/JFXC-3257] bug, for example, or [nativearray of byte|http://javafx-jira.kenai.com/browse/JFXC-3325] which will be fixed in SoMa (JavaFX 1.3?).
I tried:
var foo = "{[ 1 .. 400 ]}";
var dummy = foo.substring(0, 1024);
var buff: nativearray of Character = dummy.toCharArray();
println(sizeof buff);and I get an error: TestPlain.fx:21: incompatible types
found : nativearray of Character
required: nativearray of java.lang.Character
var buff: nativearray of Character = dummy.toCharArray();
^
1 errorAnd if I write: var buff: nativearray of Character = dummy.toCharArray() as nativearray of Character; I get a compiler crash...
I see, looking at [String(byte...) doesn't compile|http://javafx-jira.kenai.com/browse/JFXC-2852] bug, SequenceConversions class in the webrev.zip file, that we don't have a toCharArray method yet. Either an overview or some technical issue, I don't know.
So it looks like there are still some holes in nativearray support (it was presented as "experimental" in JavaFX 1.2 release announcements...).
PS.: I am not a Sun employee, I don't know Chinese, I don't have a Windows Mobile phone and I didn't even tried the mobile emulator yet (just tried, seems hard to use outside of NetBeans, which I don't have), among other problems. So I fear I am not the best help you can get, don't put high hopes on me... :-P

Remaining questions while evaluating JavaFX for a new project

Dear forum members:
currently I am evaluating the possibilities of next-generation GUI technologies, such as JavaFX, Silverlight and Flash/Flex, for a new project. To get a basic understanding of JavaFX's concepts, I worked through the available online text and video tutorials, and all the treated topics seem quite obvious/comprehensible to me +as long as one is only confronted to relatively static GUI component hierarchies+. But, as a newbie, some questions concerning more dynamically defined GUIs (i.e. dynamic JFX scripting*) still remain.
Application scenario (exemplary):
Say I want to create a "Online Shopping Application" that supports "+ShopOwners+" in *dynamically* defining the "+Shop Model+" structure, e.g. accepted visitor (client) categories, product categories their products, pricing information, payment methods, etc.
Then, based on the dynamically defined model, the shop owner should be able to design and layout the necessary forms, such as order forms, survey/feedback forms, etc. This should be done in "design mode", and there should also exist a possibility for him/her to preview the specification results in a "preview mode".
Finally, the shop owner must be able to save the model and forms on the server side in a way that can requested and run be the shopping app end users (the shop clients) via (another (?)) JavaFX frontend.
_The still remaining questions for this scenario are:_
+1. Is JavaFX appropriate for creating such kind of applications, especially when it comes to dynamic JFX scripting (and compilation) on the client side??? (By now I'm not quite sure if this is really necessary for my plans!)+
+2. Concerning the ShopOwner's GUI with its design and preview mode (and knowing that the latter mode will be the GUI version presented to the shop clients in another JFX module):+
+Is it possible to *dynamically *build up a +Scene Graph+ in a way that lets me handle and *compile* the corresponding +JFX Script+ on the client side for previewing it? Or is a client-server roundtrip absolutely necessary?
How could one persist this JFX Script on the server side? I.e., which intermediary format would be the most appropriate? => XML, JSON, JFX Script?
3. Concerning the "Shop Model", would I optimally create JFX classes or even Java Beans to bind to?
4. And finally: What would be your recommended way (software architecture) to fulfill this task in JavaFX?
Do there already exist some JFX components (dynamic forms/survey authoring modules, etc.) that persue a similar task and that I didn't find yet?
As the clarification of the above-mentioned issues are very important for me, I hope that you more experienced users can help me, pointing me to a practicable approach.
Thank you very much for any help and constructive tips in advance.
Best regards
Martin Meyers

Q1: Do I optimally need 2 different custom components for each treated concept, or do I have just 1 component with 2 internal modes (design & preview/usage)??
E.g., (a) FormSpec widget composed of LabelSpec, TextBoxSpec, ChooseBoxSpec,... widgets each having their preview pendants
Form, Label, TextBox, ChooseBox, etc.
versus
+(b) only Form widget composed of Label, TextBox, ChooseBox widgets, but all having a "design/preview execution mode".+
Closer to (b), I think, though each widget doesn't need to be modified to have design and preview modes. Instead, each widget can be wrapped within a Group to provide the design/preview functions without modifying the widget itself.
The technique is as follows. Given a sequence of widgets (Nodes, really), for each widget, wrap it in a Group that contains that widget but with an overlay Rectangle in front of it. The Rectangle can be semi-transparent, or fully transparent if you prefer. (In the example below I've made it a semitransparent color to make its location obvious as well as to provide a highlight that signals design mode.) The overlay Rectangle is set up so that its dimensions will exactly track the dimensions (bounds) of the widget behind it. I've set blocksMouse to true so that when it's present, the overlay traps events and prevents interaction with the widget. There is a boolean variable previewMode, controlled by a CheckBox, that controls the visibility of these overlay rectangles. I've also added a bit of code to track mouse events on the overlay rectangles so that you can move the widgets around when you're in design mode.
Note that the visible variable differs from transparent, i.e. opacity == 0.0. If a node is visible but is transparent, it is still eligible to receive events; whereas if visible is false, it does not receive events.
Here's some code that illustrates this technique. I'll answer your other questions in a subsequent post.

Hi,
I am trying to highlight an issue I posted earlier, about Nokia launching multiple ffdshow processes. This time with a better title maybe...
See original link here:
/t5/Nseries-and-S60-Smartphones/Multiple-FFDShow-processes-on-tray-with-Ovi-suite/m-p/778528
And if the link gets broken, google the topic with title: "Multiple FFDShow processes on tray with Ovi Suite"
There are three issues I think should be discussed:
1. Why NokiaMServer is launcing so many processes?
2. What is it doing? Converting video, but why?
3. Ffdshow is GPL'd library. Wouldn't it make NokiaMServer at least to fall under GPL licence?

Nokia's software would only have to be released under the GPL if it linked to GPL'ed software, ie. if it incorporated it into its own libraries. If it only invokes GPL'ed software (even if that GPL'ed software is bundled with it) then there are no such constraints. If there were, you'd have to release Windows under GPL as well since it can invoke GPL'ed software through ShellExecute().
Also, the software you mention looks like it is based on ffmpeg, which is normally released under the LGPL (but can be released under GPL in certain circumstances).

Create Service Agreement - In Status field, "Release" is not appearing.

Hi folks,
I am creating a simple Service Agreement in CRM Web UI. Entered all data required like Customer, product, org details, price discount etc.. and tried to "release" before saving.
In the Status field "Release" option is not there to select. I see only "In Process" and "Completed".
Can anybody tell me how to make 'Release' available, so that I can release the document and save it.
The price is not determined for the product. Could that be the reason?
The document is error free as I don't see errors in App log.
Please give me and idea to resolve. Will be generous in giving points.
Regards,
John

Hi Shashidar,
Thank you for your response. Here is the following steps I did:
1. Status profile is CRMORDER
2. In this status profile, I see the following:   Open with status No.10
                                                                    In Process - 20
                                                                    Completed - 30
                                                                    Rejected - 40
3. I added a new entry for Released with status number: 50
4. I have taken care of the Lowest and Highest Limits.
5. I also checked the 'Object Type' as 'Agreement'
Now, I am not clear which Business Trans I should assign. In the drop down list, I see many Bus.Trans for 'Release'
such as APRL - Release / CALL - Release / CREL - Release and so on.
My question is, which one of these should I select. I tried couple of them, it did not work. (Release still not appearing on CRM7.0 Web UI)
Currently, I am trying to release a Service Agreement on the Web UI. I played around with lowest and highest limits a couple of times and it changes accordingly in Web UI. But some reason 'Release' is not visible which carries the status No.50.
I wonder what is going wrong. Any help would be well appreciated with generous points.
Thank you in advance,
Fred

How do setRotationAxis and setRotate work in JavaFX 3D?

There is a texture I have to apply to a sphere. It has an arrow along equator.
When I applied a PhongMaterial with that texture to my sphere, an arrow I needed on top, was on the bottom facing direction opposite of what I needed.
I then called
                    final Sphere sphLeaf = new Sphere(R);
                    sphLeaf.setRotationAxis(Rotate.X_AXIS);
                    sphLeaf.setRotate(180.0);
Then the arrow was correctly placed on top of the sphere, but still facing wrong direction.
I thought that calling
                    sphLeaf.setRotationAxis(Rotate.Y_AXIS);
                    sphLeaf.setRotate(180.0);
would point my arrow where I needed, but instead it was now on the side of the sphere, though facing the right direction.
I thought that each call to setRotationAxis must limit rotation to that axis only. Why is there extra rotation occurring on top of what I requested?

There are two distinct ways to implement an API for applying rotations to Nodes:
1. The Node has a "current rotation" property representing the total rotation of the Node relative to the coordinate system of the Scene. The programmer can change the rotation of the Node by updating this property.
2. The Node has a method for concatenating new rotations to other transforms applied to it (i.e. providing incremental rotations).
The API supports both of these. The way it is written is for the Node to have three specific transformations (a translation, a scale, and a rotation) which can be manipulated via a set of properties (translateX, translateY, translateZ, scaleX, scaleY, scaleZ, rotationAxis, and rotate). These are all properties and obey the usual rules of properties; for example
node.setXXX(value);
assert(node.getXXX()==value);
will always succeed, assuming a single-threaded model.
Additionally, the Node supports a list of arbitrary transforms. These transforms are applied in order, before any of the three transforms above.
So to use 1. above, you can do
node.setRotate(newTotalRotationAmount);
node.setRotationAxis(newAxis); // if necessary
This is really convenient in some circumstances. For example, in an animation it's pretty straightforward to compute how much the node should be rotated (in total) based on the elapsed time of the animation. If you only had the incremental rotation, the animation would need to keep track of how long it was since the previous update (which will vary from rendered frame to rendered frame). JavaFX's animation API takes huge advantage of this, and that's why it's so straightforward to animate a rotation in JavaFX.
To use 2. above, you can do
node.getTransformations().add(Transform.rotate(...));
or
node.getTransformations().add(new Rotate(...));
depending on the rotation you need to append. This is also pretty convenient to code against.
This is fine is you have a relatively small set of rotations you're going to apply, and the result would be complex to compute (for example if they are around different axes).
The one potential problem here is that you would cause memory leaks and could potentially cause slow performance (though I suspect the implementation is written so this wouldn't happen) if you're likely to add arbitrarily many transformations this way. JavaFX 8 adds some API to the Transformation class to deal with this use case. In the most bullet-proof version this would look as follows, though you can probably reduce the code based on surrounding logic:
Rotate additionalRotation = new Rotation(...);
int numTransforms = node.getTransforms().size();
if (numTransforms==0) {
     node.getTransforms().add(additionalRotation);
} else {
     Transform updatedTransform = node.getTransforms().get(numTransforms-1).createConcatenation(additionalRotation);
     node.getTransforms().set(numTransforms-1, updatedTransform);
That seems like a pretty decent API that covers all use cases. The last use case is a little more verbose to use, and is only available in JavaFX 8, but is still not too bad. If you initialize the node to have at least one transformation in the list, and always use this idiom (i.e. just replace the transformation rather than adding any new ones), then you can reduce that to one or two lines.

JavaFX crash moving divider SplitPane

Hi all,
Java FX is giving me this error when I move several times a SplitPane Divider. What can I do to avoid it?
Thanks in advance.

Don't worry, I don't understand it well either.
> The problem there seems to be about releasing memory space when you stop showing an image or textures. This happens to me on a window (it is a desktop application) and I just move the SplitPane divider some times (it can be 20, other times 10...).
JavaFX uses hardware acceleration where it can. It also performs optimizations which are expected to perform well in a hardware accelerated environment. Some of these optimizations involve taking a snapshot image of the display and sending that snapshot to a graphics card to store in the graphics card memory so that the snapshot can be quickly accessed and used by the graphics card. Graphics processors only have a limited memory available to them, and once that memory is filled, trying to reserve any more memory will fail (which I believe is the error you see in your stack trace). The problem with the JavaFX 2.2 graphics processing pipeline is that it's aging algorithm for removing old textures from the graphics memory doesn't work quick enough to stop the graphics memory being filled up. It turns out in your case when you rapidly move the split pane divider back and forth, JavaFX keeps caching textures to the graphics hardware which eventually runs out of memory. When JavaFX is released, hopefully this issue will be resolved and will no longer occur.
Possible actions
You could try https://jdk8.java.net/https://jdk8.java.netand see if your issue is already adequately addressed.
As a work around for your application, if you have to use JavaFX 2.2 until JavaFX 8 is released, perhaps you could turn off hardware acceleration or dirty region optimizations - there are some command line switches for this, but they are not documented or supported and I don't know what they are.

Is JavaFX 1.0 Release Still GPL'd?
