💡 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 ...

  🚀 Introduction In jBPM, 📢 Signals are used to communicate across processes . They allow one process instance to broadcast an event that other processes (or nodes within the same process) can listen to and react upon . Signals are useful for: 🔔 Triggering one process from another ⏸️ Interrupting a process flow when an event happens 🔄 Synchronizing multiple running processes Unlike messages , which are point-to-point, signals are broadcast — meaning all listeners waiting for that signal will react. 🛠️ Prerequisites 💻 jBPM/Business Central & KIE Server installed ☕ JDK 11+ (or JDK 17) 🌐 Access to: http://localhost:8080/business-central 📝 Step 1: Create a Signal in Business Central 🔑 Open your project in Business Central ➕ Add a new process or open an existing one Go to Process Properties → Global Definitions Add a Signal definition (e.g., paymentSignal ) 🎨 Step 2: Using Signal Events in a Process There are three main w...
