David Salter Frank Jennings | February 2008 | Architecture & Analysis BPEL SOA Web Services Java Open Source
To gain a greater understanding of concept of SOA applications, BPEL processes and JBI applications, and to enable us to develop enterprise level SOA applications, we need to understand JBI in further depth, and how JBI components can be linked together. This article by Frank Jennings and David Salter will show the JBI Service Engine is supported within the NetBeans Enterprise Pack.

A business process is a set of coordinated activities that are performed either by humans or by tools with an objective to realize a certain business result. The order of these activities and the efficiency of those who perform the activities determine the overall performance of a business process. It is very much in the interest of every company to have business processes that are efficient and include only necessary activities, because this will allow them to work faster and more efficiently. In this article by Matjaz B. Juric and Kapil Pant, we will look at business process modeling, the main objective of which is to develop a process model that defines the existing process flow in detail.

Sitaraman Lakshminarayanan | August 2008 | BPEL SOA Web Services Oracle
The first step in protecting web services is to authenticate and authorize the web service requests. Authentication in web services is the process of verifying that the user has valid credentials to access the web services and authorization is the process of validating that the authenticated user has appropriate privileges to access the web services. Besides restricting access to users with valid credentials and proper privileges, Oracle WSM can track who accessed which service and when—to provide detailed audit trails. In this article, Sitaraman Lakshminarayanan explores how Oracle Web Services Manager can be leveraged to authenticate and authorize the web services requests.

The web services model brings into the system unique security challenges because the business data in the form of XML documents may be required to travel across untrusted networks and has the chance of being manipulated by external systems.
Throughout the entire business transaction, different classes of users and systems need access to the entire business transaction. If any part of this chain is compromised, the whole business application deployed as a service will fail. Web services are inherently about how to share the process of computing across a distributed network of systems. Web services' communication channel being XML, messages are text-based, readable, and self describing.
In this article, authors Poornachandra Sarang, Frank Jennings, Matjaz Juric, and Ramesh Loganathan explain the XML security threats and the guidelines for securing your XML Documents.

Enterprise Service Bus (ESB) is a standard-based middleware architecture that allows pluggable components to communicate with each other via a messaging system. In this article by David Salter, we will see in brief, the components inside the ESB architecture and how they communicate with each other. We will also look at how NetBeans SOA pack integrates with OpenESB and the various functionalities it offers with regards to the ESB.

Michael Havey | October 2008 | Architecture & Analysis BPEL Cookbooks SOA Web Services Java Oracle
So far, the general approach towards SOA has been that it is just a tidying-up of application integration. SOA, according to this approach, is not about building new a business functionality but about organizing existing systems. In this article by Michael Havey, we will see that, in reality, SOA is more than merely getting organized. Its principal mandate is to build something new; indeed, SOA is fundamentally about building new processes. We will consider an approach to SOA architecture that is, yes, methodical, but has the burden of actually designing new and challenging orchestration and ESB processes.
In this article, we will build examples of choreography and orchestration, study best practices for message handling in orchestration processes, and develop fundamental orchestration concepts, such as interaction, invisible hub, and deferred choice.

Integration is a necessary evil using which we can interconnect systems, applications and services to facilitate seamless information flow within and across Organization boundaries. We have been using technologies like JSP, EJB, JMS, etc. in the Java world for building Enterprise Applications (EA). But if we have to interconnect such applications, we will need Enterprise Application Integration (EAI). Many a times we also use EA technologies and tools to do EAI. This will give a short term solution to our integration problems, which may not scale up when we want to perform integration at Enterprise (Customers, Vendors, Partners, ...) level. Java Business Integration (JBI) is the new specification trying to fill this gap of EAI in the Java world. So next time when you want to integrate, don't write a single line of Java code, instead plug and assemble JBI based integration libraries to control your message flow! Does it looks promising? Believe it or read the article below to get yourself convinced.
In this article by Binildas Christudas, we will look into Integration in general and to JBI and ESB in particular. We will then explain few functionalities usually done by integration components like protocol conversions, content transformations, etc., with some code snippets too.
