Tutoriel jBPM Workflow — Inclusive Gateway expliqué

 Dans les workflows métier, il arrive que plusieurs chemins doivent être exécutés selon certaines conditions — mais pas forcément un seul ni tous.

Exemple :

  • Si montant > 10 000 → validation manager

  • Si client nouveau → vérification KYC

  • Si produit fragile → contrôle qualité

Parfois une seule condition est vraie, parfois plusieurs.

Pour cela on utilise le Inclusive Gateway (OR Gateway).

Cette architecture est couramment utilisée dans les environnements microservices modernes.

📌 Qu’est-ce qu’un Inclusive Gateway ?

Le Inclusive Gateway permet d’activer une ou plusieurs branches simultanément selon les conditions.

Contrairement :

  • Exclusive Gateway → un seul chemin

  • Parallel Gateway → tous les chemins

  • Inclusive Gateway → certains chemins

🖼️ Diagramme Inclusive Gateway

🧠 Comment fonctionne l’Inclusive Gateway

Il existe deux comportements :

1️⃣ Division conditionnelle

Plusieurs flux peuvent démarrer si leurs conditions sont vraies.

2️⃣ Synchronisation intelligente

Le processus attend uniquement les branches réellement activées.

🛠 Exemple réel — Traitement de commande

Règles :

  • Montant élevé → approbation manager

  • Nouveau client → vérification identité

  • Livraison internationale → vérification douane

Plusieurs validations peuvent se produire en même temps.

🖼️ Exemple métier

🧾 Configuration dans jBPM

Dans jBPM Modeler :

  1. Ajouter Gateway → Inclusive Gateway

  2. Ajouter conditions sur les flux sortants

  3. Ajouter un Inclusive Gateway de synchronisation

Exemple logique

Start
  ↓
Inclusive Gateway
  ↙      ↓      ↘
Cond A  Cond B  Cond C
  ↘      ↓      ↙
Inclusive Gateway (Join)
  ↓
End

⚠️ Erreurs fréquentes

❌ Oublier le gateway de synchronisation
❌ Utiliser pour simple décision
❌ Conditions qui se chevauchent mal

🔐 Bonnes pratiques

✔ Conditions claires et indépendantes
✔ Toujours ajouter Join Gateway
✔ Tester tous les cas possibles
✔ Documenter règles métier

🎯 Quand utiliser Inclusive Gateway

Utiliser pour :

  • Règles métier multiples

  • Validations optionnelles

  • Vérifications conditionnelles

Ne pas utiliser pour :

  • Exécution parallèle obligatoire

  • Choix unique

🎯 Conclusion

L’Inclusive Gateway permet de modéliser la réalité métier :

Ni tout, ni un seul → seulement ce qui est nécessaire.

Il est indispensable pour les workflows flexibles.

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 ...
