This is a recent white paper that I have written on building a Connected Retail IT Architecture using a middleware platform. Here we discuss about the typical structure of a Retail IT system and the common problems that we face when building an agile Retail IT. This provides a reference architecture for any Retail IT system and then I try to realize it with the WSO2 Middleware platform. To become a successful business in the ever-changing retail market, the retail business must have a connected retail IT architecture. This retail IT system should be able to connect with existing legacy systems, services, and data. At the same time, it would need to cater to demanding customer needs, flexibility, and agility in exploring new markets, expanding IT capabilities inside and outside the organization (SaaS), and enhance overall performance of the IT system. This white paper will discuss the importance of creating a connected retail system today and explain how a complete middleware platform c...

Paul and myself will be doing a tutorial on ESB and Enterprise Integration at WSO2Con 2013 .  Our main focus will be on Enterprise Integration and how we can use WSO2 ESB  to solve common integration problems. PRE-CONFERENCE TUTORIALS Colombo - Thursday 7th February London - Tuesday 12th February Business success requires seamless information and event flow across departments, customers, partners, and systems. Heterogeneous message formats, protocols, identity tokens, and high message volumes often challenge integration teams. As teams scale Service-Oriented Architecture (SOA) principles of sharing, re-use, and loose coupling across integration participants and interconnect integration endpoints, an enterprise integration blueprint should include a robust and high-performance Enterprise Integration Platform. The Enterprise Service Bus is a core of this platform, enabling interconnection, mediation, management and transformation. Additionally, Registry, Message Broker and Data...

Service Chaining/Service Orchestration  R ecently, I wrote an article on Service Integration with WSO2 ESB. The main objective of that article is to demonstrate how multiple business functionalities can be integrated as an aggregated virtual service. Service Integration is a common integration problem that many organizations need to solve. This article, gives you a comprehensive understanding on how we can integrate a set of services with the use of the WSO2 ESB. An overview of fundamental concepts relating to WSO2 ESB is briefly explained, while a typical service integration scenario in healthcare is implemented from scratch.

We have just released WSO2 ESB 4.5.0, the High Performance Open Source ESB,which is the first ESB version based on enhanced WSO2 Carbon 4 platform.  I would like to give an high level overview of WSO2 ESB 4.5.0's new features and improvements.  XPath 2.0 and XSLT 2.0 support In most of the integration scenarios, we need to leverage the new features of XPath 2.0 and XSLT 2.0. WSO2 ESB 4.5.0,  comes with XPath 2.0 and XSLT 2.0 support. Also, we did a major performance enhancement with the introduction of Saxon as the deafult XSLT/XPath engine.   JSON  Integration is all about handling diverse message types. In that context, JSON plays a major role as numerous APIs are exposed via JSON.  In ESB 4.5.0, we introduce a brand new JSON implementation, which can be used to Streaming JSON (JSONStreamFormatter and JSONStreamBuilder) messages through ESB. In case, if we need to mediate message based on the message content (rather than streaming), th...

In the modern enterprise, complex business requirements are increasingly satisfied by a combination of new and existing services. Getting the right bits of information at the right place, at the right time, in the right format, and with the right protocol can be a challenge. The WSO2 Enterprise Service Bus (ESB) provides a simple solution to this integration problem by providing a rich set of integration capabilities for robust, scalable and seamless integration of such services. Topics covered include: Understanding the basics: mediators and mediation flows, proxy services, endpoints End-to-end scenario on service integration using the WSO2 ESB Heterogeneous service integration and complex message mediation features.

'Cloud Computing', a buzz words that is frequently pops out in modern day discussions with IT professionals. Being a buzz word, Cloud Computing has proven to be a confusion term with respective to most IT fields. So, rather than 'defining' Cloud Computing, its worthy to write about how it has evolved during last few years and then go for the conceptual things on Cloud Computing. Business App Nightmare Nowadays, every modern business has an Enterprise Business Application as its backbone. For instance, for a given company, it may require a Business App, to manages its human resources and to support its business process in efficient manner. Traditional Business Applications are too complex and too expensive. A traditional Business App often have most of these characteristics. Often required to have a dedicated datacentre and office space with power,cooling, bandwidth, network, servers and storage. Consists of a complicated software stack and required a team of exprets to ...

If you are looking for a Real-time XML Syntax Highlighter and in the same time you want it as a web based lightweight tool then EditArea is the perfect solution for that. In WSO2 ESB 3.0.0(up coming release) , I've integrated all the source(xml) fields with EditArea highlighter to give the use a real-time rich xml editing experience. However, the original highlighter comes with some dull colors for XML Syntax as well as for controllers. So, I modified the EditArea source and came up something like this. (It takes few seconds to load..;)) EditArea support syntax highlighting not only in XML but many other programming languages including Java,PHP, C/C++, CSS, Perl, Ruby, Python and many more. I have hosted a modified version of EditArea which supports Real-time XML Syntax Highlighting here . So, EditArea is one of the rear opensource tool that is specifically designed to support Real-time syntax highlighting for most of the popular programming languages and yet it runs with its ext...

In XML CDATA sections provide a way to tell the parser that there is no markup in the characters contained by the CDATA section. And that makes it much easier to create documents containing sections where markup characters might appear, but where no markup is intended. CDATA is commonly used for scripting language content and sample XML/HTML content. So in context of Web Services with Apache Axis, the default settings of the AXIOM StAX parser would ignore the CDATA sections and won't preserve them after the parsing is done. In coalescing mode, the parser will not only coalescing adjacent text nodes, but also CDATA sections. However there are cases that you need to preserve CDATA section after parsing and creating OMElement. So, in such a scenario you need to switch off the coalescing mode by setting a property in XMLInputFactory. (i.e.: "javax.xml.stream.isCoalescing" = false). The following code will create an AXIOM OMElement with preserving CDATA. For detailed overview...
