The ACT Framework is a powerful, full stack MVC framework designed for Java developers looking to enhance their web applications. If you’re seeking a seamless development experience, robust performance, and comprehensive feature support, you’ve come to the right place. In this article, we will guide you on how to set up and start using the ACT Framework, and also cover troubleshooting tips to ensure smooth sailing!

Installing ACT Framework

To get started with ACT Framework, you have two main methods for installation:

• Add act-starter-parent to your pom.xml:

<parent>
    <groupId>org.actframework</groupId>
    <artifactId>act-starter-parent</artifactId>
    <version>1.9.2.0</version>
</parent>

• Using Maven Archetype:

Generate a new project with the following command:

mvn archetype:generate -B \
    -DgroupId=com.mycom.helloworld \
    -DartifactId=helloworld \
    -DarchetypeGroupId=org.actframework \
    -DarchetypeArtifactId=archetype-quickstart \
    -DarchetypeVersion=1.9.2.0

Tip: Don’t forget to replace the groupId, artifactId, and appName in the script above. Alternatively, you can use interactive mode:

mvn archetype:generate \
    -DarchetypeGroupId=org.actframework \
    -DarchetypeArtifactId=archetype-quickstart \
    -DarchetypeVersion=1.9.2.0

Note that there are more ActFramework application archetypes available, which you can explore here.

Understanding ACT Framework Features

The ACT Framework is not just another Java application framework; it comes with a plethora of features designed to enhance your development workflow:

• Independent and Fast: ACT apps run as standalone applications, which means they start faster compared to servlet frameworks.
• Hot Reloading: You can make real-time changes during development without restarting the application, saving you time.
• JSR330 Dependency Injection: Built on Genie, it simplifies dependency management.
• Robust Security: ACT includes measures against CSRF, XSS, and session vulnerabilities.

A Simple Analogy: Building Your First HelloWorld App with ACT

Imagine you’re building a model house using different blocks. Each type of block has a specific function—walls, roofs, and doors—just as different parts of an application have specific functions like routing, data handling, and templating.

Here’s a simple structure to help you understand how to create your HelloWorld application in ACT Framework:

package demo.helloworld;

import act.Act;
import org.osgl.mvc.annotation.GetAction;

public class HelloWorldApp {
    @GetAction
    public String sayHelloTo(String who) {
        return "Hello " + (who == null ? "World" : who) + "!";
    }

    public static void main(String[] args) throws Exception {
        Act.start();
    }
}

In this analogy, your “blocks” are the methods and annotations you are using to structure your app, while the “walls” represent the basic framework that holds everything together. Just place the blocks where they belong, and you have built your first simple app.

Troubleshooting Tips

If you encounter issues during installation or when running your ACT applications, consider the following:

• Check Dependencies: Ensure that all required dependencies in your pom.xml are correctly set up and up to date.
• Hot Reloading not Working: Sometimes changes may not be reflected instantly; make sure you are actually in development mode.
• Configuration Issues: Review your application properties files to ensure that they are correctly tailored for your development environment.
