Getting Started with Jooby: A Manual Setup Guide

Jooby is a web framework for Java designed to facilitate the rapid development of web applications. This manual setup guide outlines the steps necessary to get started with Jooby without relying on build tools such as Maven or Gradle.

Main Points

Getting Started

• Download Jooby: You can download the Jooby framework as a JAR file from the Jooby website.

Project Structure

• Create a Basic Project Structure: Organize your project with the following folders:
  • src/main/java: for your Java source code
  • src/main/resources: for configuration files and other resources
  • lib: for external libraries (JAR files)

Writing Your Application

• Create a Simple Application: You can create a basic application by writing a Java class that extends Jooby and defining your routes.

import org.jooby.Jooby;

public class MyApp extends Jooby {
    {
        get("/", () -> "Hello, Jooby!");
    }
    
    public static void main(String[] args) {
        new MyApp().start();
    }
}

Running the Application

• Compile and Run: Use a terminal to compile your Java files and then run your application using the java command.

javac -cp "lib/*:." src/main/java/MyApp.java
java -cp "lib/*:." MyApp

Key Concepts

• Jooby: A lightweight web framework for Java that simplifies web application development.
• Route Definition: The method for defining what happens when a user accesses a specific URL (e.g., get("/")).
• Classpath: The path where Java looks for classes and packages to run your application, which includes the Jooby JAR files.

Resources

• Documentation: Always refer to the official Jooby documentation for the most up-to-date information and examples.
• Community Support: Engage with the Jooby community for additional help and resources.

By following this guide, beginners can set up a simple Jooby application and understand the basic structure and components needed to embark on Java web development.
