Installing Activiti

by Dr. Zakir Laliwala Irshad Mansuri | March 2014 | Beginner's Guides Open Source

This article by, Dr. Zakir Laliwala and Irshad Mansuri, the authors of Activiti 5.x Business Process Management Beginner's Guide, explains how to install Solr. The business process is important for any organization, but managing it is of equal importance. Business requirements frequently change for an organization. To change, manage, and understand the current business process is very hard without Business Process Management (BPM), where the execution of each system depends on the business process. For developers, implementing a business process without following any standards leads to complexity. To explain a business process to a non-technical person without any graphics leads to misunderstanding. In such situations, Activiti comes to the rescue, as it is one of the best BPM frameworks for implementing business processes in your organization. Activiti provides a platform to create a business process on a canvas, build it, and execute it on the fly. It is open source, written in Java, and distributed under the Apache V2 license.

To implement a business process using Activiti, you first have to understand the skeleton of Activiti BPM. In this article, we will show you how to download and install Activiti.

In this article, we will cover the following topics:

  • Overview of Activiti BPM
  • Downloading Activiti BPM
  • Installing the Activiti framework
  • Building your first business process

By the end of this article, you will be able to install and access the Activiti framework and implement your own business process.

So, let's take a tour of Activiti, set it up, and implement a business process.

Consuming Web Services using Microsoft Dynamics AX

by Kenny Saelen Klaas Deforche | March 2014 | Enterprise Articles

In this article, created by Klaas Deforche and Kenny Saelen, the authors of the book Microsoft Dynamics AX 2012 R2 Services, we will see how to consume a web service from Microsoft Dynamics AX 2012.

In the previous versions of Microsoft Dynamics AX, you could add a web service reference in a reference node in the AOT. This generated proxy classes and other artifacts that you could then use to consume the service. In Microsoft Dynamics AX 2012, we no longer have the option to add service references to the AOT. Instead, Microsoft Visual Studio is used to generate all artifacts, which are then added to the AOT.

How this works and how this can be done will all become clear in this article.

The following topics will be covered in this article:

  • Installing the Visual Studio Tools: We have to install additional components because part of the development takes place in Visual Studio 2010. You will learn which components to install and what exactly they do.
  • Visual Studio development: After introducing the demo service, we will create a reference for the services with the help of Visual Studio. We will take you through this process step-by-step.
  • X++ development: Finally, we will demonstrate how we can use the Visual Studio project to consume services in Microsoft Dynamics AX. You will also gain an insight into the different deployment modes that are available to deploy the project's output.
