How can I invoke JavaFX application in Java project

Question

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.

Answer 1

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.
