jBPM Workflow Tutorial: 🟢 Inclusive Gateway (OR)

 🚀 Introduction

The 🟢 Inclusive Gateway (OR) in jBPM allows a process to follow one or more paths simultaneously, depending on conditions.
Unlike ❌ Exclusive Gateway (XOR), which picks only one path, the Inclusive Gateway can trigger multiple outgoing flows when their conditions evaluate to true.

This makes it useful for scenarios like multi-step reviews, conditional notifications, or parallel-but-optional actions.

🛠️ Prerequisites

• 💻 jBPM/Business Central & KIE Server installed

• ☕ JDK 11+ (or JDK 17)

• 👨‍💼 User roles with analyst/manager

• 🌐 Access to: http://localhost:8080/business-central

---

📝 Step 1: Create a New Process

1. 🔑 Log in to Business Central

2. 📂 Create a project: inclusive-gateway-demo

3. ➕ Add Business Process: InclusiveProcess

   • Id: com.example.inclusive

   • Package: com.example

---

🎨 Step 2: Design the Workflow

1. 🔵 Add a Start node

2. 🟢 Add an Inclusive Gateway (OR)

3. 📧 Add an Email Task (Send Notification)

4. 👤 Add a Human Task (Manager Review)

5. 📊 Add a Report Task (Generate Report)

6. 🟢 Add another Inclusive Gateway (Join)

7. ✅ Add an End node

🔗 Connect as:
Start → 🟢 Inclusive (Split) → (📧 Email, 👤 Review, 📊 Report) → 🟢 Inclusive (Join) → End

---

📊 Step 3: Define Data

• Add process variables:

  • sendEmail:Boolean

  • reviewNeeded:Boolean

  • generateReport:Boolean

---

⚙️ Step 4: Configure Gateway Conditions

• 📧 Email path → condition:

  sendEmail == true
  

• 👤 Review path → condition:

  reviewNeeded == true
  

• 📊 Report path → condition:

  generateReport == true
  

👉 Multiple conditions can evaluate to true, so more than one path can run in parallel.

---

🔨 Step 5: Build and Deploy

1. 💾 Save the process

2. 🛠️ Build & Install project

3. 📦 Deploy to KIE Server

---

▶️ Step 6: Run the Process

1. Go to Manage → Process Definitions

2. ▶️ Start a new instance of InclusiveProcess

3. Set variables (sendEmail, reviewNeeded, generateReport) as true/false

4. Process follows all paths where condition = true

---

📌 Step 7: Outcomes

• If only sendEmail=true → only 📧 Email Task executes

• If reviewNeeded=true & generateReport=true → 👤 Review + 📊 Report run together

• If all = true → 📧 + 👤 + 📊 all execute before merging at the Join Gateway

🛠️ Troubleshooting

• ❌ No path triggered? → Ensure at least one condition evaluates true

• ⚠️ Deadlock? → Always add a matching Join Inclusive Gateway before End node

• 🔄 Unexpected behavior? → Verify data types (Boolean vs String mismatch)

🎯 Conclusion

The 🟢 Inclusive Gateway (OR) is a powerful way to model workflows where one or more conditions can be true at the same time.

It gives flexibility beyond ❌ XOR by enabling multi-branch execution.

You can now:

• 📧 Send optional notifications

• 👤 Request reviews only when needed

• 📊 Generate reports based on conditions

By mastering Inclusive Gateways, you can design flexible, real-world processes where business rules trigger multiple actions simultaneously.
