Top Features of Jahia SDK: What You Need to Know

Jahia SDK Tutorials: Step-by-Step Instructions for DevelopersBuilding custom applications using Jahia SDK can be a game-changer for developers looking to create robust, enterprise-level web solutions. This tutorial aims to provide thorough, step-by-step instructions to help you get started with the Jahia SDK, from setup to developing and deploying your project.

What is Jahia SDK?

Jahia SDK is a powerful software development kit that allows developers to extend and customize the Jahia content management system (CMS). With its various features, including modular architecture, RESTful APIs, and a rich set of tools, the Jahia SDK is suitable for creating responsive websites, mobile applications, and other digital platforms.

Prerequisites

Before diving into the tutorial, ensure you have the following prerequisites:

• Java Development Kit (JDK): Install the latest version of JDK (11 or above).
• Maven: Ensure that Apache Maven is installed for managing project dependencies.
• Jahia instance: A running instance of Jahia CMS, either in a local development environment or on a cloud server.
• IDE: A suitable Integrated Development Environment (IDE) such as IntelliJ IDEA or Eclipse.

Step 1: Setting Up Your Development Environment

1. Install JDK and Maven
   • Download and install the JDK from the Oracle website.
   • Download and install Apache Maven from the Maven website.

Verify the installations by running the following commands in your terminal:

   java -version    mvn -version 

1. Clone or Download the Jahia SDK
   • Visit the official Jahia SDK GitHub repository.
   • Clone the repository using:

   git clone https://github.com/jahia/jahia-sdk.git 

Step 2: Creating a New Module

1. Navigate to the SDK Directory
   Open your terminal and navigate to the jahia-sdk directory.

   cd jahia-sdk 

1. Generate a New Module
   Use the Maven archetype provided by Jahia to generate a new module.

   mvn archetype:generate -DgroupId=com.example -DartifactId=my-module -DarchetypeArtifactId=jahia-module-archetype -DinteractiveMode=false 

This command will create a new directory called my-module with the necessary files.

Step 3: Configuring Your Module

1. Edit pom.xml
   Open the pom.xml file located in the my-module directory. Update the artifactId, version, and dependencies according to your requirements.

   <groupId>com.example</groupId>    <artifactId>my-module</artifactId>    <version>1.0-SNAPSHOT</version> 

1. Create Module Configuration
   Inside the src/main/resources directory, create a file named my-module.xml to define your module’s configuration:

   <module>        <name>My Module</name>        <description>A custom module for Jahia CMS</description>    </module> 

Step 4: Developing Your Module

1. Implement Business Logic
   Add your business logic by creating Java classes in the src/main/java/com/example directory. For example, you can create a MyService.java class to handle specific tasks.

   package com.example;    public class MyService {        public String greet() {            return "Hello from My Module!";        }    } 

1. Set Up JSP Files
   If your module requires UI components, create JSP files in the src/main/resources/templates directory to render views.

Step 5: Building and Deploying Your Module

1. Build Your Module
   In your terminal, navigate to the my-module directory and run the following command to build your module:

   mvn clean install 

1. Deploy to Jahia CMS

   • Navigate to your Jahia installation directory and locate the modules folder.
   • Copy the generated JAR file from the target directory of your module to the modules folder in Jahia.

2. Access Jahia Admin Panel

   • Open your web browser and navigate to the Jahia admin panel.
   • Go to Modules and find your newly deployed module.
   • Click on Install to activate the module.

Step 6: Testing Your Module

Once installed, you can test your module by accessing the corresponding URL in your browser. If implemented
