I took a step back from React Native today and went through the Ticket Monster tutorial from Red Hat. I wanted to get more familiar with some of the tooling that Java Web developers use since its becoming more important for my day job.
I was blown away at how awesome this tutorial is.
I’ve done a couple of these in the past. The world of Java EE is scary and overwhelming sometimes. Especially compared to the simplicity of something like Flask and the magic of something like Rails. This time instead of getting bogged down in all of the details, I just pretended like everything made sense for a while and took the tutorial at face value.
This proved to be a good strategy because some of this stuff actually makes sense.
- The Java word is full to the brim of acronyms. Just ignore them for a while and pretend like you know what they mean.
- 99.999% of all tooling, tutorials, and “magic” in Java assumes you are using an IDE. Eclipse or IntelliJ are the frontrunners but there are others. Developing in Java EE makes so much more sense when you are doing so from an IDE because if you can get over the complexity of learning an IDE then it does all sorts of magical stuff to hides the complexity of Java. For example, among other things JBoss Developer Studio (based on Eclipse) allows you to;
- Automatically set getters and setters for an object.
- Reverse or Forward Engineer a DB to ORM.
- Fill out XML files in a GUI.
- Drag and Drop to create the GUI for your app.
- Java is a language that developers either hate, or love to hate. But there is a reason why it has been at the top of lists like this for the last decade.
Ultimately, even if you are allergic to Java and have no interesting in learning about the tooling of that ecosystem I think this tutorial is worth checking out because by the end of your first hour you will have:
- A RESTful API along with a standard “CRUD” app that does something
- An understanding of how data is stored and retrieved from a database
- Deploy the whole thing to a cloud service (OpenShift) for free.
These are tough concepts for a lot of beginners and I think this sample tutorial application covers them all.
