Using JavaFX and Maven

JavaFx Project using Maven

This is a demo app for hotel booking build in Java, JavaFx, Fxml, H2 Database, Tomcat. In this repo we will explain how to setup simple/fxml (without/with fxml) JavaFx application using IntelliJ.

Installations

• You only need to follow this section if you are cloning from git repo
• You need the rest of the sections only IF you want to create such project from scratch
• Clone the repo git clone https://github.com/iloveyii/hotel_frontend_maven.git
• Either use command line mvn clean javafx:run or follow the section "Run configuration" below if you want to run from IntelliJ
• The default root credentials are email: root@localhost & password: root, once logged in you can create more users.
• This JavaFx application works with hotel_backend that you can clone https://github.com/iloveyii/hotel_backend.git and follow instructions in the README.md
• If your server/backend_hotel is running on a system other than localhost you need to change url in models/Api.java line 15.

Pre Requisite

• You need to install Git, Maven, Docker, IntelliJ for your platform.

Configuration

• Open IntelliJ > New > Project

Using Maven

• mvn clean javafx:run

Distribution builds

• Build

Latest

• DOCS, and in the left menu click JavaFX and IntelliJ > Non-modular with Maven
• Latest Open JavaFX 17 link
• Latest Open JavaFX Maven 0.0.6 Plugin link

Issues

• Binding observable list to tableview does not show data but error becuase module does not open org.hotel.models to javafx.base
• Solution: the module-info.java should look like:

module org.hotel {
    requires javafx.base;
    requires javafx.controls;
    requires javafx.fxml;
    requires org.json;
    opens org.hotel to javafx.fxml;
    opens org.hotel.models to javafx.base;
    exports org.hotel;
}
