Building Optaplanner Applications using the BRMS Business Central GUI: The Missing Guide

1 Introduction

A potential customer is interested in seeing how BRMS Business Central can help him build an Optaplanner (also known as Business Resource Planner) application using the GUI alone after I demonstrated to him the Optometrist rostering app based on the Nurse Rostering sample application.

I wanted to create a simple Optaplanner app so I picked cloud balancing. The problem statement for cloud balancing can be found here:

A sample implementation can be downloaded here:

However, the rules in the sample implementation are in native .DRL syntax. The customer wants to see everything created using Business Central GUI tools, if possible. This is the reason why I wanted to re-create this example using Business Central.

Please note that you have to add the “plannermgmt” and “kie-server” roles to you user login to Business Central in order to see the Optaplaner-specific GUI and manage the execution server. Continue reading Building Optaplanner Applications using the BRMS Business Central GUI: The Missing Guide

BPMS/BRMS 6.3: An Intelligent Process Server Odyssey

The Journey Begins

With the release of BPMS/BRMS 6.3 back in May, I think it is time for me to embark on a journey to explore its new features. What better to do than migrate an existing business rules application which I deployed on the Realtime Decision Server in BPMS 6.1 to 6.3’s new Intelligent Process Server. A piece of cake, so I thought… Continue reading BPMS/BRMS 6.3: An Intelligent Process Server Odyssey

Building a JBoss BPMS Web Application using jBPM Form API

(This article assumes some basic knowledge of the JBoss BPM Suite including using Business Central.)

JBoss BPMS forms are generated and customised by business analysts when they create business processes. The forms are usually used for kicking off a business process instance and interacting with the user when the process reaches a user task eg, for a manager to manually approve a loan. Few customers use the forms on the BPMS Execution Servers. They prefer to build a web application that interacts with a business process remotely running on a BPMS Execution Server to gain fine-grained access control, consistent look-and-feel and better client interaction. The main issue is how to use the forms generated on the BPMS server from the web application. There was no easy way to do that until the recent release of JBoss BPMS 6.1.

Robot Programming using JBoss BRMS

One of my hobbies is building robots. After programming several robots, I say to myself: there’s got to be a better way of doing this. You program the behaviour of a robot using a micro-controller. Every time you want to make a change, you have to re-flash the on-board non-volatile flash memory. If you compare this practice with enterprise applications, it is similar to that of many older enterprise applications which embed business logic in code. The solution is to move the embedded business logic (in our case, the robot behaviours programmed on micro-controller) out to be managed and executed by a business rules engine. This is exactly what I did. And I call my robot CepBot. Continue reading Robot Programming using JBoss BRMS

Building a JBoss BPMS Rules Application without Writing Code

This article assumes some basic knowledge of the JBoss BPM Suite including using Business Central.

JBoss BPM Suite (BPMS) and JBoss Business Rule Management System (BRMS) 6.1 introduced a new component called the Real-time Decision Server (RTDS). Rule projects built using BPMS can be deployed directly onto the Real-time Decision Server via Business Central. Applications can instantiate and execute rules on the RTDS using either a REST or JMS interface.

In this article, I am going to show you how you can build a rule-based application without writing even a single line of Java code. The application aims to rate locations for placement of mobile speed cameras. It is an example application I made up and is not being used by any Police Departments. My simplified speed camera placement rating criteria are based on: Continue reading Building a JBoss BPMS Rules Application without Writing Code
