JAVAFx Build Failed

Question

I created an app with JavaFx for windows, which is really cool. I can run it from e(fx)clipse, everthing works fine, but I can't make a jar file from the project. I can export it (Right click->Export->Runnable Jar File). However, if I run the jar on MAC OS X , in the menu bar I get "java" menuitem instead of my application name ,which i really don't like. I searched for how to hide that menuitem, or just rename it, and I found that I have to rename the "Application title*" in the build.fxbuild file. Now I can't build it.

So this is what I really want: to remove/hide/rename the "java" menuitem in Mac OS X. If you have any experience, please share it with me. I will be really grateful :) .

I get the following error when I try to run the build.xml file:

[javac] Compiling 22 source files to C:\Users\Hassan\Desktop\Programming\workspace\Raktar_vevo 2.7\build\classes

Thanks you very much for your help!

Answer 1

You need to setup jdk as jre in Prefereces->Java->Installed JREs, and check it as "separate jre" in External Tools Configuration->JRE in case of Eclipse

Edit: Run > External Tools > External Tool Configuration

Answer 2

When you new the JavaFX Project, the generated file, build.xml, maybe have wrong file path.

<?xml version="1.0" encoding="UTF-8"?>
	<project name="App2" default="do-deploy" basedir="."  xmlns:fx="javafx:com.sun.javafx.tools.ant">
	<target name="init-fx-tasks">
		<path id="fxant">
			<filelist>
				<file name="${java.home}\..\lib\ant-javafx.jar"/> <!-- wrong path -->
				<file name="${java.home}\lib\jfxrt.jar"/> <!-- wrong path -->
			</filelist>
		</path>
	
		<taskdef resource="com/sun/javafx/tools/ant/antlib.xml"      
			uri="javafx:com.sun.javafx.tools.ant"
			classpathref="fxant"/>
	</target>

you have to check that where are the ant-javafx.jar and the jfxrt.jar ? For example, JDK 1.8 the two files are in the difference place, C:\Program Files\Java\jdk1.8.0_20\lib\ant-javafx.jar C:\Program Files\Java\jre1.8.0_20\lib\ext\jfxrt.jar

so now I only find the way to modify by myself...

<?xml version="1.0" encoding="UTF-8"?>
	<project name="App" default="do-deploy" basedir="."  xmlns:fx="javafx:com.sun.javafx.tools.ant">
	<target name="init-fx-tasks">
		<path id="fxant">
			<filelist>
				<file name="C:\Program Files\Java\jdk1.8.0_20\lib\ant-javafx.jar"/>
				<file name="C:\Program Files\Java\jre1.8.0_20\lib\ext\jfxrt.jar"/>
			</filelist>
		</path>
	
		<taskdef resource="com/sun/javafx/tools/ant/antlib.xml"      
			uri="javafx:com.sun.javafx.tools.ant"
			classpathref="fxant"/>
	</target>

after modify the files, right click choose the Run as Ant Build!

I have a little better solution with less modification:

This fix path issue (just add ext\ to fix issue)

<path id="fxant">
    <filelist>
        <file name="${java.home}\..\lib\ant-javafx.jar"/>
        <file name="${java.home}\lib\ext\jfxrt.jar"/>
    </filelist>
</path>

Before doing this, you need to have a jdk1.8.xxx in your installed JREs list, not the jre included in the jdk package but jdk itself.
Next, in Run\External Tools\External Tools Configuration open the JRE tab and check that Execution environment is CDC-1.1/Foundation-1.1 (jdk1.8.xxx)
That's all !
