Use JavaFX in a Swing or console app

This short post explores how to integrate JavaFX into a legacy console or Swing application.

Assuming you’ve created an application such as the WebView Sample, create a separate thread to launch JavaFX’s Application class

Thread appThread = new Thread(() -> {

To allow us to control when JavaFX will exit, disable implicit exit. Implicit exit happens when the last window (Stage) is closed by calling hide() or close(). Add this snippet of code to the start() method to JavaFX’s Application class


To run code on JavaFX Application thread

Platform.runLater(new Runnable() {
  @Override public void run() {
    // code runs on JavaFX thread

To exit gracefully when legacy application exits


Run Node.js in a Docker container

In this post, I explore how to run a Node.js web application in a Docker container based on the StrongLoop Process Manager image. I also have a requirement to export and deploy the Docker container to a server that lacks internet access.


Create a new Node.js web app using express-example-app as the starting point

git clone

Head into the app folder and install dependencies

npm install

Start application using PM

slc start

Access http://localhost:3001 in a browser to ensure it works.

Shutdown PM

slc ctl shutdown

Create a new Docker container using StrongLoop PM image as the starting point

docker run --detach --restart=no --publish 8701:8701 --publish 3001:3001 --name strong-pm-container strongloop/strong-pm

Deploy example app by running following command in directory of app

slc deploy http://localhost:8701/ master

Access http://localhost:3001 in a browser to ensure it works.

Discover container’s id

docker ps -a

Commit container to a new image

docker commit 653811fd29f3 myimage

Save image to tar file

docker save -o myimage.tar myimage

Load image file in a new Docker instance (on another machine)

docker load -i myimage.tar

Run image in a new container

docker run --detach --restart=no --publish 3001:3001 --name strong-pm-container myimage

Access http://localhost:3001 in a browser to ensure it works.
