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's
Also, 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

Flex Builder, debugger and web application: how?
Hello,
I'm traying to setup a project in eclipse with both a java
web application (servlets, jsp) and flex applications as a
frontend. So I installed flex builder as a plugin on an eclipse+web
standard tools, then created a WST web application project, and
used the "Add flex nature.." of the flex plugin. I don't want to
use the flex data services.
Now, in a standard run (I installed a tomcat 5.5 and
configured it in eclipse), my mxlm files are being correctly
compiled into swf, and they are successfully calling my servlets
(which simulates a backend xml-based interface).
I'm having problems in debug: if I launch the debug profile
related to tomcat, the normal version of the sfw will be used (even
manually switching to the "-debug" version, it says that a running
flex debugger has not be found on localhost). On the other way, if
I launch the debug as a "flex application", it seems to work (it
stops at breakpoints) but my tomcat is not started at all, the swf
is accessed as a local file and all call to my servlet will fail..
so it will stop working almost immediately.
There is a way to setup eclipse to start standard java
debugging with tomcat *and* the flex debugger?
Thanks
CosmaI found a workaround of sorts for the problem: don't
terminate the applications!
Previously, I would terminate the application using either
the Terminate button in the Debug view or by closing the tab in the
browser (Firefox). Now I just let them pile up in the browser and I
rarely see this problem.
In other words, I was having lots of trouble when doing
Launch-Terminate-Launch-Terminate... but now I just
Launch-Launch-Launch... and clean up once in a while. -
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. -
Is JavaFX Desktop application able to run in a Windows XP machine with only JRE installed?
If yes, how could I execute an application implemented in JavaFX using the JavaFX command or some else?
I build a jar package and I would like to delivery to my client just this jar and a batch file to run this application.
Thanks,
André RezendeIf you want to run a javafx program or a java program with javafx GUI you need the javafx runtime, the easiest way is to install javafx in the client, if this is a problem, you can include the javafx runtime in your application and include it in the classpath

Java and Partner Applications - EXTREMELY URGENT
gurus,
i'm trying to register a single sign on servlet application as a partner application.
i followed ths steps as mentioned in the SSO SDK version 307 and when i try to run the application i get the following error -
******* START ERROR ********
Error oracle.security.sso.enabler.SSOEnablerException: oracle.security.sso.enabler.SSOEnablerException: java.sql.SQLException: ORA-06510: PL/SQL: unhandled user-defined exception ORA-06512: at "DVIPARTAPP.WWSEC_SSO_ENABLER_PRIVATE", line 304 ORA-06512: at line 1
********* END ERROR *********
the environment here is -
database - 8.1.7
portal - 3.0.8
os - windows NT
has anyone faced the same problem before.
any help would be greatly appreciated.
thanx a bunch.
nullThank you very much once again for your prompt reply and suggestions. I tried the later solution using Developing Statically Protected PL/SQL (or j2ee) Applications described in Oracle® Application Server Single Sign-On Application Developer's Guide 10g (9.0.4).
Protect the servlet(or jsp) by entering the following lines in the mod_osso.conf file:
<Location /servlet>
require valid-user
authType Basic
</Location>
When this particular application added inside the portal (try to web clipp, it redirects to SSO login page.) In this case users have to login twice. Once to the default portal page, and another to this stand alone out side application. Defeats the purpose of SSO using Portal.
Your question "is it an app that you want to be able to invoke from a link within Portal?" hits the nail right on the head. The difference here is, I do not want to add as a page link, ideally I want this web application to be able to web clipped inside the portal.
Now, this is the external application (and not developed as a portlet). I have not completely understood how any web application developed as a portlet can get the user information (user/groups/roles etc) when user logs in to portal default page. And, the authorization is implemented inside this web application. They(users) do not need to authenticate once again since that is done when they login to the portal. I hope I am making sense.
I am not clear on the web application developed as a portlet. Can users, groups, and roles be implemented inside this application? If it is developed as portlet. The problem here is you have to rewrite all of your existing applications as a Portlet (either PL/SQL or J2EE). Not all applications are developed using this technology.
Your help is highly appreciated.
Very Best Regards,

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. -
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.
ThanksYou 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"); -
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} -
How to pass Objects from Java App to JavaFX Application
Hello,
New to the JavaFX. I have a Java Swing Application. I am trying to use the TreeViewer in JavaFX since it seems to be a bit better to use and less confusing.
Any help is appreciated.
Thanks
I have my Java app calling my treeviewer JavaFX as
-- Java Application --
public class EPMFrame extends JFrame {
Customer _custObj
private void categoryAction(ActionEvent e) // method called by Toolbar
ocsCategoryViewer ocsFX; //javaFX treeviewer
ocsFX = new ocsCategoryViewer(); // need to pass in the Customer Object to this Not seeing how to do it.
// tried ocsFX = new ocsCategoryViewer(_custObj) ; nothing happened even when set this as a string with a value
public class ocsCategoryViewer extends Application {
String _customer;
@Override
public void start(Stage primaryStage) {
TreeView <String> ocsTree;
TreeItem <String> root , subcat;
TreeItem <String> root = new TreeItem <String> ("/");
root.setExpanded(true);
ocsTree = new TreeView <String> (root);
buildTree(); // this uses the Customer Object.
StackPane stkp_root = new StackPane();
stkp_root.getChildren().add(btn);
stkp_root.getChildren().add(ocsTree);
Scene scene = new Scene(stkp_root, 300, 250);
primaryStage.setTitle("Tree Category Viewer");
primaryStage.setScene(scene);
primaryStage.show();
public static void main(String[] args) {
_customer = args[0]; // temporarily trying to pass in string.
launch(args);JavaFX and Swing integration is documented by Oracle - make sure you understand that before doing further development.
What are you really trying to do? The answer to your question depends on the approach you are taking (which I can't really work out from your question). You will be doing one of:
1. Run your Swing application and your JavaFX application as different processes and communicate between them.
This is the case if you have both a Swing application with a main which you launch (e.g. java MySwingApp) and JavaFX application which extends application which you launch independently (e.g. java MyJavaFXApp).
You will need to do something like open a client/server network socket between the applications and send the data between them.
2. Run a Swing application with embedded JavaFX components.
So you just run java MySwingApp.
You use a JFXPanel, which is "a component to embed JavaFX content into Swing applications."
3. Run a Java application with embedded Swing components.
So you just run java MyJavaFXApp.
You use a SwingNode, which is "used to embed a Swing content into a JavaFX application".
My recommendation is:
a. Don't use approach number one and have separate apps written in Swing and Java - that would be pretty complicated and unwarranted for almost all applications.
b. Don't mix the two toolkits unless you really need to. An example of a real need is that you have a huge swing app based upon the NetBeans platform and you want to embed a couple of JavaFX graphs in there. But if your application is only pretty small (e.g., it took less than a month to write), just choose one toolkit or the other and implement your application entirely in that toolkit. If your entire application is in Swing and you are just using JavaFX because you think its TreeView is easier to program, don't do that; either learn how to use Swing's tree control and use that or rewrite your entire application in JavaFX. Reasons for my suggestion are listed here: JavaFX Tip 9: Do Not Mix Swing / JavaFX
c. If you do need to mix the two toolkits, the answer of which approach to use will be obvious. If you have a huge Swing app and want to embed one or two JavaFX components in it, then use JFXPanel. If you have a huge JavaFX app and want to embed one or two Swing components in it, use a SwingNode. Once you do start mixing the two toolkits be very careful about thread processing, which you are almost certain screw up at least during development, no matter how an experienced a developer you are. Also sharing the data between the Swing and JavaFX components will be trivial as you are now running everything in the same application within the virtual machine and it is all just Java so you can just pass data around as parameters to constructors and method calls, the same way you usually do in a Java program, you can even use static classes and data references to share data but usually a dependency injection framework is better if you are going to do that - personally I'd just stick to simply passing data through method calls. -
Starting and stopping applications via a Java-application on Windows/Unix
Hello,
I want to start java and other applications via a java application.
This java application should start several different applications on windows and
on unix systems and take care of their current state (e.g. running/not running).
For all applications to be started there are .sh-scripts for unix and .bat-scripts
for windows. In the scripts there could be a java call, e.g. "java someApplication",
or some executables could be called. These scripts set the applications' environment etc.
and start the application finally.
My java application calls these scripts via the ProcessBuilder API, which is working fine.
But there is the following problem: on windows, when executing a script that starts
some other application, the ProcessBuilder gives me process-handle to the started
process. If calling destroy() on this handle, only the cmd.exe gets killed which
started the application. The application itself is running on. This is undesired behaviour
since I want to be able to control the started applications, at least start and stop it which
is impossible that way.
On unix, it is working when using
"exec java someApplication"
instead of just
"java someApplication"
in the .sh-scripts. The exec command substitutes the shell process with the underlying
process started in the script, so everything is working as expected on unix.
But how could I get this working on windows systems? Is there any equivalent to the exec
command on unix? Any suggestions appreciated.
If something's unclear in my description, please let me know.Yes - after looking at this option - I think that's the direction I am going to go. It probably makes sense to give my JMS topics and my BPEL server their own OC4J instances anyway - for a number of reasons.

Any way to distribute a javafx application with embedded JRE as a standalone?
Hey,
I'm looking for a way to distribute my javafx app, but I want a customer to be able to run it as a standalone (i.e. without installation).
I know I can distribute a jar file but it's without the embedded JRE.
Only way I see to embed a JRE is via building an installer.
Any way I can distribute say an EXE file that when double clicked just runs the app with JRE embedded inside?I have already read that guide.
Here's the relevant section:
Table 3-1 JavaFX Execution Modes
Execution Mode
Description
Run as a standalone program
The application package is available on a local drive. Users launch it using a Java launcher, such as java -jar MyApp.jar, or by double-clicking the application JAR file.
Launched from a remote server using Web Start
Users click a link in a web page to start the application from a remote web server. Once downloaded, a Web Start application can also be started from a desktop shortcut.
Embedded into a web page
JavaFX content is embedded in the web page and hosted on a remote web server.
Launched as a self-contained application
Application is installed on the local drive and runs as a standalone program using a private copy of Java and JavaFX runtimes. The application can be launched in the same way as other native applications for that operating system, for example using a desktop shortcut or menu entry.
According to this, only way to use a private JRE is via the 4th option which means installation. -
What are the better IDE's for Mac (Java and C++)?
I'm switching over to Mac's here soon and I'm curious about which products are the best, from others' experiences, for developing Java and C++ applications. On Windows I used NetBeans and IntelliJ (although not as much), but I'm curious if there is Mac specific software that someone might recommend.
Both of the above work fine on Mac (I used IntelliJ exclusively for Java development). For C++ I use Qt Creator and sometimes Xcode.

Using JavaFX to rewrite GUI layer for Java Desktop Swing application
From the faq's on javafx.com I read the following:
I currently build applications in Java. Can I reuse my Java libraries in JavaFX Script?
Yes. You can leverage the power of Java by using any Java library within a JavaFX application.
This way you can preserve your investment in Java and use JavaFX to build engaging visual experiences.
Can I use JavaFX to develop a user interface for my Java program?
While it's easy to write your application in JavaFX and call into Java where necessary,
the inverse - writing a Java application that calls into JavaFX for the user interface - is not yet true.
We expect this to be addressed in the near future.
* Perhaps I'm missing something, but I do not see the difference between the two questions, but they give completely different answers?
* We have a swing application that we might want to use JavaFX to replace the current Swing user interface, however, we also have alot of business logic / communications code written in
* Java that we aren't going to rewrite.
Could someone tell me why the two questions have different answers?
Thanks. Cheers.Hi Josh,
I'm facing serious issue trying to invoke a javafx class from my java code. Could you please suggest a way to do it. Even hacks would be ood enough for now.
I have created file Clock.fx. When run individually from my IDE (i'm using NetBeans) it works fine. But when i try to invoke it from a java class in project in throws exception.
public static void main(String[] args) {
ScriptEngineManager manager = new ScriptEngineManager();
JavaFXScriptEngine fxEngine = (JavaFXScriptEngine) manager.getEngineByName("javafx");
System.out.print("created fxEngine");
try {
Object o = fxEngine.eval ("Clock { property: \"Clock\" }");
fxEngine.invokeMethod (o, "create");
} catch (Exception ex) {
ex.printStackTrace();
I get following exception
Exception thrown in JavaFX pretty printing: java.io.FileNotFoundException: \tmp\___FX_SCRIPT___.fxdump from StringInputBuffer (The system cannot find the path specified)

How can I invoke JavaFX application in Java project
I want to set an actionlistener on a button.When I click the button,it will run the JavaFX application.
Any idea?Thanks in advance.A program that launches JavaFX programs? Something like this might work:
* Launches the given JNLP file.
* @param jnlpFileURL The url to the JNLP file of the JavaFX application we are launching.
public void launchFXApplication(String jnlpFileURL) throws Exception {
//Retrieve the runtime.
Runtime runtime = Runtime.getRuntime();
//Create the commands we will be executing.
String[] commands = new String[] {
System.getProperty("java.home") + File.separator + "bin" + File.separator + "javaws",
jnlpFileURL
//Execute it.
final Process process = runtime.exec(commands);
//Need to read the input.
final BufferedReader errorReader = new BufferedReader(
new InputStreamReader(process.getErrorStream()));
final BufferedReader outputReader = new BufferedReader(
new InputStreamReader(process.getInputStream()));
//Input MUST be read and should be done in separate threads.
Thread errorThread = new Thread(new Runnable() {
public void run() {
String line;
try {
while ((line = errorReader.readLine()) != null) {
//Examine it if you like. Optional.
errorReader.close();
} catch (IOException ex) {
ex.printStackTrace();
Thread outputThread = new Thread(new Runnable() {
public void run() {
String line;
try {
while ((line = outputReader.readLine()) != null) {
//Doing something with the input is optional.
errorReader.close();
} catch (IOException ex) {
ex.printStackTrace();
//Run the separate threads.
errorThread.start();
outputThread.start();
//Wait until it's done.
process.waitFor();
}This code will of course need to be signed if you intend to launch it as an applet or via webstart.

Start JavaFX application from Java
Hello,
I have the following scenario:
I have a small JavaFX application and a big Java application. Now the Java App should call the JavaFX App to start up.
Further the JavaFX App has to call some methods from the Java App. Is this possible?
What is the best approach for my scenario?
Maybe somebody has made some experiences ..
thanks!
Edited by: 799878 on 03.11.2010 07:54"Now the Java App should call the JavaFX App to start up."
I'm assuming that the JavaFX code and the Java code are in the same application, correct? If so, then there are hacks available, but no standard way to start up JavaFX from Java will exist until the APIs have been ported from JavaFX script to Java.
"Further the JavaFX App has to call some methods from the Java App. Is this possible?"
Yes. Java can be called from JavaFX just fine. Just be careful if you use multi-threading or time consuming operations, since JavaFX script is apparently single threaded. Also be aware that netbeans normally compiles JavaFX applications with JSE version 1.5, so library features that did not exist until later versions will not be available by default.
