Components are king in the world of pluggable ESBs ...

In the world of light-weight pluggable ESBs supporting a SOA approach (or EAI, or MoM, ...) the richness of the component ecosystem is a very important aspect.  Part of Project OpenESB's purpose is to provide a standards-based framework onto which components can be fabricated and easily deployed.

Recently Frank implemented a nice page redesign that lists the components and allows you to select different views, such as by contributor, by status, etc.  Nice job Frank :)

A few days ealier than expected ...

GlassFish ESB milestone 2 arrives.  It now includes Data Mashup capabilities and is feature complete.

Security provisioning through the ESB

Project OpenESB is a community that is intended to derive multiple solutions and components all sharing a single platform based on JBI.  Another example of this is a solution in a sub-project called keychain.  Keychain is an early stage project that attempts to solve the problem of how to provision identities against legacy applications.  Essentially it provides a gateway, built on top of the ESB platform, that exposes an "SPML compliant" provisioning interface which can be accessed by any SPML compliant application or just send an SPML document across HTTP/SOAP.

The gateway will then route this request, suitably transformed, to the legacy application to execute the particular provisioning (create, update, delete of user information) request.  Again, this is an early stage project that is driving the creation of new ESB adaptors and will later drive the evolution of the platform into an "appliance-like" package.  So far, to show the breadth of the potential application of KeyChain, there are early examples of provisioning to RACF, Salesforce.com, and LDAP.

GlassFish ESB arrives ...

Our first milestone for GlassFish ESB is now available. This commercially supported form of our open source community technology has been a regularly requested step for us to make.  We would have done it sooner but had been busy with the major release of our larger Composite Application Suite which shares the same foundation. More on the timeline for our final release and the contents of GlassFish ESB can be found here.

Growing our appeal ...

One of our big goals for Project OpenESB is to extend the development domains to which it is applicable.  ESB have traditionally been associated as platforms to support message-oriented-middleware (MoM) and more recently service-oriented architecture (SOA).  SeeBeyond also pioneered bringing very strong EAI capabilities to its' ESB with ICAN. However the range of application segments keeps expanding with very notable areas of growth in the web-build-out (Web2.0, "web as a platform"), event-processing (EDA), etc.

Some of these new terms try to better define or put a new spin on established ways of doing things, some are more "marketectures" to help highlight key advantages of certain platforms to certain problem domains.  What is true is that many of these new "styles of development" do contain valuable principles and patterns that have broader applicability.  Our goal with Project Open ESB is to create a platform that encompasses as many of these styles as make sense.

We believe that we can more easily achieve this with our modular, micro-kernel architecture based on JBI and being evolved through Project Fuji.  As of today OpenESB supports: MoM, SOA and EAI patterns and in the very near future we will be adding "event-driven-architecture" (EDA) to our platform with our soon to be released IEP service engine component in October'08.  The IEP leverages research from Standford and others on event stream processing techniques and the continuous-query-language (CQL).  If you want to find out more about event processing you might want to read this paper published on JDJ written by Bing and Prabhu who work on the IEP.

Community collaboration ...

One of the great things about moving all of what we do to a community-based model is that it greatly increases our flexibility and how we can respond to demands in our marketplace.  There are many other benefits but to me the flexibility it provides our customers and us is one of the most important.

One example of increased flexibility is enabling customers to "mix-and-match" product components supplied in commercial software suites with incubating components within open source.  Communities also leverage each other driving by the needs within those communities.  Here is a recent example blending Apache Camel with JBI and Open ESB ...
