IBM BPM Configuration build Java Integration Service integrated into Java components

This article also discusses a simple operation scenario that invokes a local method by passing simple, array-based data.

IBM Business Process Manager V7.5 is a comprehensive, reusable business process management platform that provides management and visibility of business processes. It integrates key features from Websphere®process Server, WebSphere Lombardi Edition, and IBM integration Designer into a unified user environment, including a unified library, Create tools and run-time environments to design, execute, monitor, and optimize business processes. IBM Business Process Manager V7.5 is especially useful for helping process owners and enterprise users directly participate in business process improvements.

IBM Business Process Manager (BPM) provides integrated services to accomplish tasks by integrating external services. Integration Services include WEB services integration and Java integration components. However, on many occasions, external systems are implemented based on the C language, and customers do not want to reconstruct their existing C-based implementations for architectural, performance, or other reasons. This is a bottleneck when selling java-based products, because integration is a very complex process.

To integrate java-based applications and C-based APIs, you need to build a bridge between the two programming language APIs. Java Native Interface (JNI) is a local programming interface that is part of the Java Software Development Kit (SDK). JNI enables Java code to use code and code libraries written in other languages, such as C and C + +. You can create shared, JNI-based library implementations to exchange information between two different languages. These libraries are available in two formats:. dll (dynamic-link library), for Windows® based programs, and. So (shared objects), for unix-based platforms.

This article will introduce you to some of the steps to integrate IBM BPM and JNI implementations on the Windows platform, including creating a local DLL using JNI, and configuring the library to generate Java integration Services in Business Process Manager , and integrates Java components.

We'll discuss a simple action scenario that shows how to invoke a local method by passing simple data and array-based data.

For

To perform the steps in this article, you will need to install IBM WebSphere Business process Manager V7.5, IBM Integration Designer V7.5, and IBM Process Designer V7.5.

Create a local shared library

This section describes the steps for creating a local shared library, such as a Windows environment DLL. You will do the following:

Create a stand-alone Java project

To create a stand-alone Java project in the IBM Integration Designer (hereafter referred to as integration Designer), go to File > New > Java projects. Name the project and press Next, as shown in Figure 1. Set default output folder to the class directory, which needs to be explicitly created through integration Designer.
