Java and JavaFX
Hi,
How can I integrate java in the javaFX class?
I need my graphical application take data from file. I'd want using java file api in the javaFX.
Thanks
You can use a Java class inside of a JavaFX class similarly to a JavaFX class. Only major difference is instantiation:
import java.io.File
var file : File = new File("some path");

Build java and javafx applications
Hello everybody! Currently, I am building a netbeans project that consist of java and javax applications and the questions are :
1. How to call java object in javafx object or it reverse. Which one the better?
2. How to compile and run the project that consist of java and javafx applications.
Help me, please!Thank'sAlso, If you want to call JavaFX methods from Java you can use interface and have the JavaFX class extend it (interfaces are extended in JavaFX)
For example, make interface FXAdapter.java
interface FXAdapter {
public void modifyLayout();
}And in your FX class
public class FXClass extends FXAdapter {
public override function modifyLayout() : Void { /*Implementation*/ }
}Now in your java class you can ask for FXAdapter as a parameter and pass a FXClass object -
Is it possible to have java and javafx project types combined ?.
Today, in NetBeans (not sure about the eclipse world) one has to decide between a "Java" project or a "JavaFX" project.
Why can't these two be combined ?.
For e.g, when I try to add JavaFX files (script, classes) to a Java Project it fails to compile. I poked around Netbeans and googled a bit and could'nt find any answers.
The only way that I can make it work is to create a JavaFX project and Java code to it.
In situations where one is attempting to "add" JavaFX to an existing Java/Swing app the current approach is too weird and abnormal.
For e.g Amy Fowler's excellent guide http://weblogs.java.net/blog/2009/06/10/insiders-guide-mixing-swing-and-javafx should be such that I should be able to "simply" add JavaFX code and NetBeans should take care of the plumbing. (calling javafx compiler, adding the right jars for runtime ...)
/rkI'm not sure how JavaFX works, but it is built rather differently from "normal" Java (Single threaded, high level of abstraction from the actual implementation, etc). It is easy to use Java classes inside a JavaFX class, but the reverse is not true.
Plus, though this part is technically fixable, some classes installed inside the JRE don't seem to work by default in a netbeans JavaFX project. -
Integrating Java and JavaFX..?
Hi
I am a new bee to JavaFX. I have a Java program which connects to the MySql Databas and fetches the data and prints the data, and also I have written a Java FX program for my GUI. Is there any way for me to integrate these two program so that the data fetched by using the Java program can be used in Javafx. If is there any way plz let me know.
Or
Is there any other way for me to connect to the MySql Database through JavaFx
Edited by: Ajaybvs on Feb 15, 2010 7:35 PMIt is a common question that have been answered several times on this forum.
I suggest to try and use the search facilities...
But in short, in JavaFX you instantiate Java objects as usual (var x = new JavaObject();) and you can use them freely. -
Hola!
I wondered how I could use a JavaFX class inside a Java class. Like this:
FXClass.fx
package fxpackage;
public class FXClass {
var chiquito: Integer;
JavaClass.java
package javapackage;
import fxpackage.FXClass;
public class JavaClass {
FXClass fxVar;
}With this example, Netbeans marks the import statement as an error, arguing that the package "fxpackage" doesn't exist.
Am I doing something wrong? Or does a .java file not descry a package with no .java files??Without testing anything something like that:
//Interface
public interface FXCall {
public void call();
//JavaFX side
package test;
public class FXImpl implements FXCall {
public override function call(): Void {
Alert.inform("call from javaFX);
public class JavaTest {
public static void main(String[] args) {
FXObjectValue fxov = FXLocal.getContext().findClass("test.FXCall").newInstance();
FXCall fxcall = (FXCall)fxov;
com.sun.javafx.runtime.Entry.deferAction(new Runnable() {
@Override
public void run() {
fxcall.call();
{code} -
Difference between Java applet and JavaFX
Hello, all!
I am studying javaFX in general. As far as I understand there is no main difference between java applet and javafx, except javafx has different syntax and library simple to use. Is it right?Basically, yes. But as you point out, it is supposed to be faster to develop in JavaFX...
For example, Processing allows to export to applet, and is strong on doing graphics, but to see if user has clicked on a circle, you have to check the mouse coordinates against the circle coordinates, or create your own Circle class: it is at a much lower level.
Likewise, you can use gaming frameworks like Slick2D or PulpCore, but they might be lacking on GUI (but perhaps faster). Or use Apache's Pivot, strong on GUI, but perhaps lacking a bit on graphics and animation.
It depends on your needs, if you prefer to stick to Java, etc. -
Is JavaServer Faces and JavaFX the same?
Nope, Java FX was only announced in May 2007 whereas JSF has been around for a few years now. JSF is a framework and JavaFX are a series of products.
Try looking up Wikipedia for the info:
http://en.wikipedia.org/wiki/Java_FX

Hi guys
It's a bit unclear at this stage as to what to do to get Netbeans and Javafx updated correctly.
Do I need to still be downloading the Development version of Netbeans or have the plugin fixes been applied to Netbeans 7.01 now?
The new development Netbeans indicates that it supports JavaFx as part of the package.. so does that mean you still need to install all of the plugins?
It's confusing and slowing down development a lot - especially with updating javafx across multiple machines and the documentation is not covering
how best to move from one build of Javafx to the next and how to also ensure Netbeans is setup correctly.
-- some history since build 42 we could not package our app with netbeans. So we installed the development netbeans and had to muck around with the platform
manager to get it to work with javafx. It has been somewhat inconsistent across several machines also - some with win7 and some XP.
I understand that being part of a beta requires some patience but some guidance in how others are keeping their windows based development environments working properly
would be great!You need to use the latest beta of NetBeans 7.1. I suspect the older version you downloaded is using JFX1.x.
See this: http://netbeans.org/kb/docs/java/javafx-setup.html
Regarding your threading model, there is a new API for threading but I wouldn't say it's much simpler or easier - at best, more powerful.
There doesn't seem to be any good official docco on this however (seems like a big important topic so this is weird - maybe I just missed it). The closest is this slightly outdated article: http://fxexperience.com/2011/07/worker-threading-in-javafx-2-0/
You may also find this useful: Thoughts on best practices for busy/wait and threads?
If you have further questions on this stuff, probably best to start a new forum topic (or reply to the threading one above) - this thread is starting to lose relevance to it's original topic.

getting package javafx.json and javafx.gui not found errors.... have the package names changed ,, if so pls tell new names of these packages ......Hi Josh,
thanks for your quick reply. I agree that javafx.gui has been replaced by javafx.scene package.
But can't find reference to javafx.json package.
Saw its use on http://blogs.sun.com/clarkeman/entry/javafx_script_and_json_weather .
I'm trying to pass a json from my java code and use it in my javafx code. But in javafx code it comes as plain string -

BI Java and BI ABAP -RSPLAN issue
Hi All
We are working with BI system ,using BI 7.0 Java and BI ABAP as separate systems on same host.
Already run the template intaller for BI Java and ABAP integration.
But facing some issue ,when going ot BI ABAP and RSPLAN and clicking the Start Mideller
it is opening a browser as http://host:8000/sap/public/myssocntl?sap-client-XXX
Since this is not correct and it should open BI Java portal instead of ABAP stack page.
Instead this should open a Url like this http://host:5XX00/webdynpro/dispatcher/sap.com/biplanworkbench1/Modeler?
I check on BI ABAP system under SAP Reference IMG -> SAP Customizing Implementation Guide-> SAP NetWeaver _> Business Intelligence-> BI Integrated Planning -> Settings for Starting the Planning Modeler.
There the default Url is BEx Portal Server and the url is
http://host:5XX00/webdynpro/dispatcher/sap.com/biplanworkbench1/Modeler
Can anybody let me know why this is going to ABAP server instead it should go to Java.
Regards
Ajay

Please suggest .

How to get return value from java and read by other application?
i want to read return value from java and the other application read it.
for example:
public class test_return {
test_return(){
public int check(){
return 1;
public static void main(String args[]){
new test_return().check();
}from that class i make as jar file. How to read the return value (1) by other application?
thx..If your installer is requiring some process it invokes to return a particular value on failure, then the installer is seriously broken. There are a bazillion commands your installer could invoke, and any of them could fail, which in turn could invalidate the entire install process, and any of them could return any value on failure. The only value that's consistent (in my experience) is that zero means success and non-zero means failure, with specific non-zero values being different in different programs.
About the only control you have over the JVM's exit code is that if your main method completes without throwing an exception, the JVM will have an exit code of 0, and if main throws an exception (either explicitly or by not catching one thrown from below), it will be non-zero. I'm not even sure if that's guaranteed, but I would guess that's the case.
EDIT: I'm kind of full of crap here. If you're writing the Java code, you can call System.exit(whatever). But nonetheless, if your installer requires certain exit codes from any app--java or otherwise--you have a problem.

Problem with java and flex web service
Hi,
I have a basic web service written in java using jax ws 2.1
ri. I need to call it from Flex using the WebService class
Annotations for the java web method :
@WebMethod
public void Login(
@WebParam(name="server") String serverURL,
@WebParam(name=AUTHENTICATE_HEADER,header=true,mode=WebParam.Mode.INOUTHolder<Authenticate Header>
authHeader)
When I try and call the service from Flex , it can't find the
login method and attempts to call it fail. If I set the web service
to RPC based using @SOAPBinding , the method is found but then
there are issues with the authentication header.
What do I need to do to get flex web services communicating
succesfully with java ?
Are there are any known compatibility issues ? Or guidelines
for going about this ?
Any help would be appreciatedwell Shay,
i've used JDev's tools to developer and to deploy the web service: the war and ear files are automatically generates you to the end of the process.
I have included all the files java and the compiled classes, but I do not have files jar.
But don't works: if i create only one java class with all code inside then it works fine!!

Hi,
In running the following simple code, I have gotten different results using java and javaw.
public class Test {
public Test() {
public static void main(String[] args) {
int x =4;
System.out.println("The value is "+ ((x > 5)?6.0:4));
System.out.println("The value is "+ ((false)?6.0:4));
System.out.println("The value is "+ ((true)?99:9.9));
Using java, I get the following results:
The value is 4.0
The value is 4.0
The value is 99.0
But using javaw, I get the following results:
The value is 4.0
The value is 4
The value is 99
Any ideas why this is so?
Thanks for any help.
GilbertI used JBuilder to run the following code and Jbuilder uses javaw.
By the way, the correct answer is the one using java right? -
Problem with Java and Zip Files
Hello there everyone. I have a problem with trying to zip up directories with empty folders in them. They zip fine with my code, but according to winzip, the number of files in the archive is incorrect. It's supposed to have a total of 288 files in it, but when it's zipped up, it only says 284. I mention specifically the "empty directories" note because the zipping works fine without empty folders.
Below is the code for the zip method:
public static void zip(File[] list, File zipfile, File zipRoot)
throws IOException {
if (!zipfile.exists()) {
zipfile.createNewFile();
else if (!zipfile.isFile()) {
throw new IOException("The zip file, " + zipfile.getAbsolutePath()
+ " is not a file.");
if (list.length == 0) {
LOG.error("The list of files to zip up is empty.");
for (int i = 0; i < list.length; i++) {
if (!list.exists()) {
throw new IOException("The file or directory, " + list[i].getAbsolutePath()
+ " does not exist.");
FileOutputStream fos = new FileOutputStream(zipfile);
ZipOutputStream zos = new ZipOutputStream(fos);
for (int i = 0; i < list.length; i++) {
if (LOG.isDebugEnabled())
LOG.debug(i + ": " + list[i].getName());
String entryName = getRelativeName(list[i], zipRoot);
if (list[i].isDirectory()){
if (list[i].listFiles().length == 0){
ZipEntry entry = new ZipEntry(entryName + "/");
zos.putNextEntry(entry);
else {
ZipEntry ze = new ZipEntry(entryName);
zos.putNextEntry(ze);
byte[] buffer = new byte[8096];
FileInputStream fis = new FileInputStream(list[i]);
int read = 0;
read = fis.read(buffer);
if (LOG.isDebugEnabled())
LOG.debug("\tFound " + read + " bytes.");
if (read == -1){
//empty file, but add it for preservation.
//zos.write(buffer,0,0);
while (read != -1) {
zos.write(buffer, 0, read);
read = fis.read(buffer);
fis.close();
zos.closeEntry();
zos.close();
The files look like they're there, but I need the system to be able to determine the number correctly.
Here's the interesting thing: It zips the files, and then when I use the size() method for zip files in java, it says 284 files. But when I unzip, it says 288 again. It's like there's files missing when compressed, but when decompressed, they return. Note that the files are actually there. If I open the archive in a third party app such as Winzip AND Winrar AND IZarc, they all show 288 files. Any idea what would make the number of files appear incorrectly in a zip file when zipped by java with the code above? Thanks in advance.
- ChrisI figured out the problem. When zipping files in windows using winzip, it doesn't explicitly count folders as a "file/folder" as a file in itself. It will create the folders for files to go in, but the folder itself will not be 'counted' when you query the info of the file itself. You have more control of the zip file in java, and can count the folder as a file or not.
