Tutoriel jBPM Workflow — Tous les Gateways BPMN expliqués

 Dans un workflow BPMN, les Gateways contrôlent le chemin que doit suivre le processus.

Ils permettent :

  • Prendre des décisions

  • Exécuter des tâches en parallèle

  • Activer plusieurs conditions

  • Synchroniser des flux

Comprendre les gateways est essentiel pour modéliser correctement un processus métier.

Cette architecture est couramment utilisée dans les environnements microservices modernes.

📌 Types principaux de Gateways

En BPMN (et dans jBPM) on utilise principalement :

  1. Exclusive Gateway (XOR)

  2. Parallel Gateway (AND)

  3. Inclusive Gateway (OR)

  4. Event-Based Gateway

🖼️ Aperçu des Gateways

1️⃣ Exclusive Gateway (XOR)

👉 Choisit un seul chemin

Utilisé pour décision simple.

Exemple :

Paiement accepté → expédition
Paiement refusé → annulation

🖼️ Exemple XOR

2️⃣ Parallel Gateway (AND)

👉 Lance toutes les branches en parallèle

Le processus attend que toutes soient terminées.

Exemple :

Validation RH + Finance + Manager

🖼️ Exemple AND

3️⃣ Inclusive Gateway (OR)

👉 Lance une ou plusieurs branches selon conditions

Exemple :

Montant élevé → validation manager
Client nouveau → vérification identité

🖼️ Exemple OR

4️⃣ Event-Based Gateway

👉 Attend un événement externe

Exemple :

Paiement reçu OU délai expiré

🖼️ Exemple Event-Based

🧠 Comparaison simple

Event-Based1 (événement)Attente événement

⚠️ Erreurs fréquentes

❌ Confondre OR et AND
❌ Oublier synchronisation
❌ Mauvaise condition XOR

🔐 Bonnes pratiques

✔ Toujours tester tous les scénarios
✔ Documenter règles métier
✔ Ajouter gateway de synchronisation
✔ Éviter logique complexe dans un seul gateway

🎯 Conclusion

Les gateways sont le cœur de la logique BPMN.

Bien choisir le bon gateway permet :

  • Workflow correct

  • Moins d’erreurs

  • Meilleure performance

OOPs Concepts in Java | English | Object Oriented Programming Explained

Image
🔹OOPS (Object Oriented Programming System) in Java Object-Oriented Programming (OOPS) is a programming paradigm that uses classes and objects to design software. It simplifies development and maintenance by applying key concepts: 📌 Class: Class   is a user-defined data type which defines its properties and its functions. Class is the only logical representation of the data. For example, Human beings in an organisation is a class like Employee. The age, name, department, salary etc. of a human being/employee are its properties, and the jobs performed by the employees in an organisation are known as functions.  The class does not occupy any memory space till the time an object is instantiated. A class is a user-defined data type that defines properties and functions. For example: Class: Employee Properties: name, age, salary Functions: work(), attendMeeting() A class does not occupy memory until an object is created. ...

Scopes of Signal in jBPM

Image
💡 Introduction Signals in jBPM 7 are a core part of event-driven workflow design. They allow asynchronous communication between process instances, making it possible to start , interrupt , or coordinate processes without direct linking. However, signals can have different scopes , which define how far the signal travels and who receives it . Let’s explore the four available scopes in detail: 🔹 Process Scope 🔹 Default Scope 🔹 External Scope 🔹 Project Instance Scope 🧩 1️⃣ Process Scope 📘 Definition Process scope signals are local to a single process instance or its child subprocesses . They are not visible outside that instance hierarchy. 📋 Use Case Used for communication inside the same process , like triggering subprocesses or event sub-processes. 🖼️ Process Scope Example Below is an example of a simple process-scoped signal. Only this process (or its subprocess) will catch this signal. ⚙️ 2️⃣ Default Scope 📘 Definition The default scope ...

jBPM Installation Guide: Step by Step Setup

  jBPM Installation Guide – Step by Step for Beginners If you are starting with jBPM (Java Business Process Management) , the first step is to set up your environment. In this guide, we’ll walk through how to install jBPM, configure it, and run your first business process. 🔎 What is jBPM? Before we dive into installation, a quick recap: jBPM is an open-source Business Process Management (BPM) suite , written in Java, that allows you to model, execute, and monitor workflows using BPMN 2.0 standards. It can run standalone , embedded in applications , or deployed on a Java EE server . 🖥️ Prerequisites Before installing jBPM, make sure you have: Java JDK 11 or later (Java 17 is commonly used) Maven 3.x (for building and managing dependencies) Git (optional, if you want to clone sample projects) A Database (H2, MySQL, PostgreSQL, or Oracle) – jBPM ships with H2 for testing At least 4GB RAM (8GB recommended for Workbench & KIE Server) 📦 Download ...
