Compiling 8u20-b26 for iOS
Hi,
I'm trying to compile OpenJFX 8u20-b26 for iOS but run into problems with
the web project. The first problem seems to be with the ios.gradle script.
IIUC (I have very limited experience with Gradle) it disables the
compilation of the ordinary web Java code:
compileJava {
enabled = false
}
and then builds the iOS specific web Java code:
afterEvaluate {
def compileWebJavaIos = task(compileWebJavaIos,
type: JavaCompile, group: Build) {
The problem with this is that the builders project gets built before the
compileWebJavaIos task is run and there is code in builders which depends
on the web classes (e.g. WebViewBuilder depends on WebView) so I get a lot
of unknown symbols Gradle builds the builders project. E.g.:
[ant:javac]
/Users/niklas/Projects/openjfx/modules/builders/src/main/java/javafx/scene/web/WebViewBuilder.java:60:
error: cannot find symbol
[ant:javac] WebView x = new WebView();
[ant:javac] ^
[ant:javac] symbol: class WebView
[ant:javac] location: class WebViewBuilder
I'd like to fix this but before I make a serious attempt I'd like to know
whether I'm doing something wrong. I have Gradle 1.8 installed and I am
building using the 1.8.0_20-b26 JDK. OS X is 10.9.4 and I have the latest
Xcode 5.1 installed. I'm using this command line to build
gradle -PCOMPILE_TARGETS=ios -PUSE_LIPO=true -PIOS_VERSION=7.1
Also, how is the jfxrt.jar that comes with my Java8 installation treated by
the build? I guess it is ignored since otherwise I wouldn't get any
compilation problems due to missing WebView etc since those classes are in
Java8's jfxrt.jar?
Thanks!

Re: Compiling 8u20-b26 for iOS
I couldn't keep my hands off and by looking at how it's done in
dalvik.gradle from javafxports [1] I managed to get it to build the iOS
web.jar. Here's the patch for ios.gradle:

Let me know if you want me to create a JIRA and post this there instead.
This patch helped me get past the first problem with the builders project
failing. I then had to fix a few compilation problems in the web module's
iOS code. A few classes (PopupFeature and PromptData) were missing and a
few of the others had to be brought up to date with the code in src/main/.
Haven't been able to test the patched web iOS code yet but at least it
compiles now. I should probably create an issue for all of this and attach
a patch, right?

you can just locally disable the builders or add a dependency on the
compilation task for the IOS web files.
As to your other question, Richard is right that we omit lib/ext from
compilation, but there can be issues in doing this (e.g., when running
tests or building apps). We recommend that you remove (not just rename) the
jfxrt.jar from the JDK you use to build.

The jfxrt.jar that comes with the JDK is in the lib/ext directory (as is
Nashorn). We simply omit both from the class path when we build by setting
java.ext.dirs= (to empty).

Re: IPA / APK Internal
For IPA generation with RoboVM it's pretty simple since the compiler can be easily embedded and run programmatically from within Java. Please have a look at the RoboVM Maven plugin for a sample on how this is done: https://github.com/robovm/robovm-maven-plugin On Mon, Dec 30, 2013 at 9:27 AM, Mike mikeg...@gmail.com wrote: I know this is a difficult question, but who can give us some advice on what to study up on regarding APK / IPA Generation and a RAD tool for Javafx built on JDK8 I'm laying the ground work for doing this and I'm not certain the best tools to use from inside a Rad tool to help developers build such file types. We plan on having an APP that runs (dashboards) (templates) built from within a RAD tool on a desktop but this doesn't allow developers to make their own APK and IPA's I'm familiar with out Appery.io and other platforms use Phonegap as help in this process but I'm curious how developers think a Javafx jdk8 building platform should do the same.

Re: JavaFX on iOS and Android: The real problem and challenge
Here's a crazy idea for you guys: how about contributing to RoboVM instead and maybe, just maybe, it would one day become more than a one man project? ;-) I'm of course very aware of the problem you're facing with JFX+iOS and as I said to some of the Oracle guys at J1 I'm very tempted to making it an option to use the OpenJDK class lib with RoboVM and support invokedynamic. These are the major things missing from RoboVM in order to use it with a vanilla OpenJFX8 build (and not the jfx78 backport). I WILL do this work at some point but it's not at the top of my list of priorities. If I could get some help on other things I can get to it sooner. I'm a bit surprised that you're considering starting from scratch with a new project and not building on previous work. Is there something fundamentally wrong with RoboVM, something that cannot be fixed that is preventing you from using it? What would you gain from starting from scratch with OpenJDK? AFAIK there's no AOT compiler in OpenJDK. And you probably cannot reuse code from hotspot (like the GCs) since it's pure GPLv2 (no classpath exception) and it would contaminate the rest of the app's code and force it to be GPL as a whole since you have to link everything statically on iOS (note: this is my interpretation of the GPL, IANAL!). As for RoboVM being a prototype, experimental and not production ready. Yes, it's immature and there are bugs in there but every project is in the beginning (even OpenJDK subprojects ;-) ). It will evolve in time and the more people who use it and contribute the sooner it will mature. Also, all of those terms are subjective. I've stopped saying that it's not production ready myself because for some people it is ready! There are already apps in the App Store developed by others that are working fine and prove this (let me know if you're interested and I'll provide a list of those I'm aware of). In the long term we will provide professional services (support contracts, add-ons, etc) around the RoboVM open-source project. We hope that we can hire a team that can work on this full-time and build a healthy community around it. In the short term our biggest problem is resources, both in terms of man-power and financially. We've been contacted by some companies which would consider sponsoring this project. If you work for a company which would benefit from Java on iOS becoming a reality than please try to convince your management to sponsor. Who knows, if we would focus more on OpenJFX and OpenJDK maybe we could even get some help from Oracle? Perhaps start a petition in the JavaFX community to try to persuade Oracle into supporting RoboVM?

Re: JAVAFX on ANDROID
I don't think a Java6 backport is necessary. If the jfx78 backport works on RoboVM it should work on Android (provided that the native stuff is there of course). The problem is the dx tool which doesn't accept Java7 .class files, right? IIUC not much happened to the class file format between Java6 and Java7 (except for invokedynamic and what is need to support it but Java7's javac never generates invokedynamic ops). The APIs to support try-with-resources (AutoCloseable) is already in Android and the syntactic sugar added in Java7 (multi-catch, switch on string, diamond, etc) compiles to Java6 compatible bytecode and uses no new APIs. So it should be easy to make a tool using ASM or similar which takes the jfx78 jar file and rewrites the .class files in it to target 1.6 instead of 1.7 and repackage as a new jar. Just my €0.02. If you want to maintain a backport of the backport :-) then go for it. On Mon, Oct 14, 2013 at 8:53 AM, Matthias Hänel hae...@ultramixer.comwrote: Hi Stefan, thanks for your fast answer.

For PlatformLogger et al you can probably use the compatibility lib we have been using for jfx78+RoboVM: https://github.com/robovm/robovm-jfx78-compat Den lördagen den 12:e oktober 2013 skrev Tomas Brandalik: I think that PlatformLogger initialization in CssHelper was causing problems.

Re: JavaFX and iOS - it will remain a dream
after many days trying to really build iOS apps with JavaFX and RoboVM or Avian I’m very frustrated because of the following things: Based on RoboVM, JavaFX on iOS runs unacceptable slow - I don’t know the reason - maybe it’s the rendering model of JavaFX - maybe it’s the currently unoptimized RoboVM One big problem of RoboVM is it’s dependence of the Android library, it does not support the OpenJDK. That’s a big reason for many many problems when using JavaFX. So currently it’s not possible to use fxml files (FXMLoader) because of the missing Stax xml parser and classes like XMLInputFactory in the android library… There's now a compatibility library for the jfx78 backport which includes the missing sun.* classes from OpenJDK [1]. So that will not be a problem when running on RoboVM/Android. Daniel Zwolenski is working on getting this into Maven which will make it nice and easy to develop with RoboVM+OpenJFX. FXMLLoader relies an StAX and the Java Scripting API. Those can both be made to work on RoboVM/Android. The POM of the compat project [1] contains optional dependencies on the StAX API and JSR 223 API. For StAX you'll also need a StAX provider [2][3]. For scripting you'll need a JSR 223 implementation of the scripting language you're using, like Rhino for JavaScript [4][5]. Please note that I haven't tested FXML but it should work (in theory at least ;-) ). Please give it a go. It will be a great blog story if you can make it work on iOS. As for the performance issues with RoboVM+OpenJFX: those WILL be addressed! You can either wait for it to happen or you can help out. One way to do that would be sample code that exercises the code paths that need to be optimized (e.g. the button rendering you posted about earlier).

Will this converter be able to precompile embedded JavaScript? That would be very cool. If I remember correctly Rhino can compile JS to bytecode AOT.

very poor performance on iOS :(
Please try running with perfLogger and also Instruments. As I've pointed
out before RoboVM is in early stages of development. It doesn't do release
builds yet. Virtually nothing has been done yet to optimize things for
speed. So my guess is that you will find that a lot of time is spent in
RoboVM code. Also, AFAIU the Oracle guys have run this on iOS internally
and have seen decent performance (can someone confirm?). That would also
suggest that RoboVM is the problem at the moment.

Re: JavaFX8 on iPhone! It works!
Even the latest version of Android are missing these classes and Dalvik (the VM in Android) doesn't support invokedynamic so a backport is required, not just for RoboVM. I managed to get Ensemble working yesterday on iOS with the jfx78 sources and RoboVM. But even this backport contains code which won't work on Android nor on RoboVM. E.g. I had to patch FontFileWriter to get Ensemble working (it uses java.nio.file.Files which is a Java7+ class). IMO the backport needs to target Android/RoboVM specifically and not Java7. A first step would be to make it compile with Java6.

I assume in order to compile the graphics repo of JFX8 I need an OpenJ8 JDK already installed? Are there pre-built bundles for this (for mac) or do I need to checkout and build myself? Does anyone know which repo, and what command line arg should I use to build J8 in this case?

I’m testing now all the basic JFX controls (like button, RadioButton, CheckBox, ListView, TableView, ...).

Re: OpenJFX on iOS using RoboVM
Tom, could it be due to some class missing? Do you get an exception? If you launch the app with the -rvm:log=warn option failing Class.forName() calls will be logged. RoboVM strips out classes not being referenced to keep down the size of the app. The compiler has to be told about classes that get loaded using reflection. That's what the -roots command line option and the roots section in the robovm.xml file are for. You may have to add a root there for the class(es) containing the effect code. Or you could just add root**.*/root and RoboVM will compile and link in everything.

Please make your work available as soon as possible so others can try it out. I have played a bit with RoboVM and looked into what would be required to port JavaFX to it but did not get the time to do a deep dive. Are you using the OpenJDK for the class libraries?

I'd like to say thank you for writing such great code! BrickBreaker almost worked out of the box! I had to remove/stub out font related stuff of course and PlatformLogger had to be copied from OpenJDK. Also had to fix a tiny bug in the native glass code [2] and an NPE in PlatformUtil.getRTDir() when PlatformUtil.class isn't available in any jar file [3]. Do you have an ETA on the open-sourcing of the font related code? It would be a fun challenge to get most
