Building SOA-Based Composite Applications Using NetBeans IDE 6

May 1, 2010 by BPELforum

Product Description

In Detail

Composite applications aid businesses by stitching together various componentized business capabilities. In the current enterprise scenario, empowering business users to react quickly to the rapidly changing business environment is the topmost priority. With the advent of composite applications the `reuse’ paradigm has moved from the technical aspect to the business aspect. You no longer re-use a service. You re-use a business process. Now enterprises can define their own behaviors optimized for their businesses through metadata and flows. This business process composition has become increasingly important for constructing business logic.

The ability of composite applications to share components between them nullifies the distinction between actual applications. Business users should be able to move between the activities they need to do without any actual awareness that they are moving from one domain to another.

The composite application design enables your company to combine multiple heterogeneous technologies into a single application, bringing key application capabilities within reach of your business user. Enterprises creating richer composite applications by leveraging existing interoperable components increase the organization’s ability to respond quickly and cost-effectively to emerging business requirements.

While there are many vendors offering various graphical tools to create composite applications, this book focuses on using the BPEL service engine from the OpenESB project for solving business integration problems. Project OpenESB implements an Enterprise Service Bus runtime using Java Business Integration (JBI) as the base. This allows easy integration of web services to create loosely coupled enterprise-class composite applications.

The objective of this book is to help enterprise application architects and developers to understand various SOA tools available as part of the NetBeans IDE that will enable them to build an enterprise-grade, scalable application in a short period using a single development interface. The NetBeans SOA tools form an open-source and freely available add-on to the NetBeans IDE that is targeted for enterprise application development. This pack contains open-sourced features from Sun’s Java Studio Enterprise and Java CAPS products, as well as all-new features for creating composite applications, BPEL-based web services, secure Java EE web services, and real-world XML artifacts like XML Schema and WSDL. Part of NetBeans Enterprise Pack is integrated with NetBeans 6.0, so you don’t need to download additional add-ons or plug-ins if you are using NetBeans version 6.0 or higher. However, not all OpenESB components are integrated with NetBeans 6.0. For instance you may not be able to create an Intelligent Event Processor using the standard NetBeans IDE; these components can be downloaded and installed into the NetBeans IDE.

What you will learn from this book?

Basic understanding of SOA and BPEL Processes
Setting up NetBeans IDE, OpenESB runtime, and BPEL engine
Designing BPEL processes
Packaging and deploying BPEL processes
JBI runtime and GlassFish Application Server.
Using the JBI service engine in NetBeans
OpenESB Binding Components, Service Engines, and other tools
Using the WSDL Editor for enterprise applications
Rapid development and testing with the XML schema designer
Working with the Intelligent Event Processor (IEP) module and the IEP Service Engine
Fault handling within a BPEL process

Approach

This book introduces basic SOA concepts and shows how you can use NetBeans and OpenESB tools to design and deploy composite applications. After introducing the SOA concepts, you are introduced to various NetBeans Editors and aids that you need to understand and work with for designing a composite application. For example you are introduced to a WSDL editor before dealing with web services. The last part of the book deals with a full-fledged incremental example on how you can build a complex composite application with key screenshots accompanied by the source code available on the website.

Who this book is written for?

This book is for enterprise developers and architects interested in using NetBeans IDE and OpenESB tools to build their SOA based applications.

Latest SOA Need: Assistance with JBI Application Integration

April 28, 2010 by BPELforum

The methodology of Enterprise Integration has advanced to Service Oriented Architecture (SOA) because of its ability to weave disparate applications and services to produce a business structure where data can flow as a business process. Environments have been built over time with diverse layers of applications. The development time and maintenance cost to manage these layers is driven down when integration components are built on standards. The most compelling standard in the integration space is Java Business Integration (JBI) which allows for the creation of a Service Oriented Architecture with interchangeable components that are vendor-independent.

Isn’t all development easier with a standard?

Not really. Don’t confuse the ease of using the standardized run-time components with the creation of those run-times. The creation of JBI run-time components is a whole new technology, with layered naming conventions and rules for each binding and service engine components. As with any new technology, JBI brings with it a sizable learning curve.

Plan time to learn JBI technology

Developers interested in JBI will need to reserve some time to learn. This type of exposure is mostly reviewing code snippets from existing open source JBI applications, like ServiceMix, and supplementing that learn-as-you-explore strategy with the 228 page JBI specification document publicly available from the Java Community Process organization. SOA integration experts, like Scott Ganyo with Moongate Technologies, agree that it can take a long time to learn the rules of the JBI spec nomenclature and nuances to code within the standard. While it is not brain surgery, even an experienced integration developer will need to devote targeted time to get up to speed.

The Holy Grail of Simplified Integration

So here is the hitch. Everybody is focused on SOA, and the push-point of that statement is everybody is everybody, from code crunchers to web designers.

The use of standards, like JBI, simplifies the combining of components but it is the ability to make those high-learning-curve standards accessible to all levels of coders that is the Holy Grail enterprises will be striving to acquire.

Less sophisticated audiences, one proven method

It is an early adopter assumption to think everyone using your product knows what they are doing. The first implementers of any new technology will cater to the most sophisticated users. But the SOA audience is as varied as the many applications they are trying to integrate, so this market will need a splay of products to cover different levels of expertise. A graphical interface, as we have seen successfully implemented in workflow and business process applications, is a proven method to simplify the design and implementation process. Just as BPEL maps out high-level business processes as a workflow, an intuitive graphical interface for the lower level integrations has a definite market for a technical user that wants to keep their distance from the detail specifications and simply drag and drop functionality.

Graphical Interfaces hide mundane details from developers

If vendors create graphical interfaces that generate standards-based code under the covers, a developer can avoid understanding the intimate details of the specification while still enjoying the benefits of developing a standards-based integration. A robust graphical interface allows each SOA developer to visualize the integration path and then simply click to define the properties in a fill-in-the-blank format. This expands the standards-based playing field to include a broader base of developers. The true beauty of the interface is to ultimately create standards based code so that the resulting run-time components integrate easily with other internally and externally developed components.

Graphical Interfaces are not always a priority

It is a certainty that more organizations will eventually go the graphical direction. First vendors develop the functionality and then they make it easier to reuse. While a couple of vendors have already started down a user-centric graphical path, an across-the-board improvement to robust graphical interfaces for integration will take a year or more.
