Welcome to the world of j2html! This powerful tool allows developers to generate HTML directly from Java code in a typesafe manner. With j2html, you can create stunning web pages while enjoying the benefits of Java’s type safety and security. In this article, we will guide you through the steps to get started with j2html, including code examples and troubleshooting tips.

Step 1: Add j2html as a Dependency

To start using j2html in your project, you need to add it as a dependency. Depending on whether you’re using Maven or Gradle, follow one of the options below:

For Maven Users:

    com.j2html
    j2html
    1.6.0

For Gradle Users:

compile 'com.j2html:j2html:1.6.0'

Step 2: Import TagCreator and Start Building HTML

Once you’ve added the j2html dependency, you can start creating HTML content in your Java application. Below is a simple example to illustrate:

import static j2html.TagCreator.*;

public class Main {
    public static void main(String[] args) {
        body(
            h1("Hello, World!"),
            img().withSrc("img/hello.png")
        ).render();
    }
}

Understanding the Example

Let’s break down the above code using an analogy. Imagine you’re a chef in a kitchen (your Java application), and the ingredients you have are the various HTML tags (like h1, img) provided by j2html. Instead of cooking in an unorganized manner (writing raw HTML yourself), j2html allows you to arrange your ingredients in an orderly fashion. You list down what you need (create the body element with a heading and an image) and serve it up in a neat plate (render it to HTML).

The Resulting HTML

The Java code will produce the following HTML output:

    
        
Hello, World!
        
    

Troubleshooting Common Issues

If you encounter any issues while using j2html, here are some troubleshooting tips:

• Dependency Issues: Ensure that you have included the correct dependency for either Maven or Gradle as shown above.
• Compilation Errors: Make sure you have imported the j2html package correctly using the import statement provided.
• Rendering Problems: Check your HTML output for any syntax errors — HTML is sensitive to proper structure.
