I’m finally finding some time to take a look at WebSphere ESB 6.0.2. The endpoint lookup mediation primitive for determining endpoint addresses based on information retrieved from WebSphere Service Registry and Repository was near the top of my list of things to try. Just as I was about to give up hope of getting it to work, a note arrived from Greg Flurry pointing out that you need to have Fix Pack 1 of Service Registry and Repository. Importantly, he also included a link to the install documentation in the InfoCenter. The update failed the first time as my machine was crawling along and the SOAP connection timed out. Having shutdown a few spare processes the fix pack went on fine and the primitive now works like a charm. Note that you can also install directly from the fix pack.

Service Registry and Repository Fix Pack 1
Friday, December 8th, 2006The first Fix Pack for WebSphere Service Registry and Repository is now available. The support site only lists a single APAR fix but thanks to Arnauld for pointing out the README file that details the substantial set of improvements that come with this release:
- Added support for WebSphere Application Server ND.
- Install improvements to allow manual database creation.
- Install improvements to allow remote database.
- Ontology API now includes access via Web Services.
- Performance improvements when making large datagraphs governable.
- Performance improvements when importing a large data set.
- Retrieval of data objects can be limited to a depth of 0, 1.
- Additional languages now supported
Customizing the Service Registry and Repository UI
Friday, December 1st, 2006One of the beauties of WebSphere Service Registry and Repository product is it’s flexibility. The development team have begun a new developerWorks series looking at customizing the web based administrative console. The first article covers the basic architecture and concepts but the series promises to go on to cover the ultimate in customization: a new perspective.
developerWorks articles
Thursday, November 9th, 2006Another bumper crop of developerWorks articles this week, particularly in the WebSphere ESB space. Charlie Redlin kicks off an essential new series for anyone looking to take WebSphere Process Server or WebSphere ESB in to production. Charlie heads up the bring-up team that have been providing invaluable intellectual capital around deployment topologies. It is great to see that some of this is now going to make it out in to the public domain. For those at the other end of the scale, just getting started with WebSphere ESB, there is a new introductory tutorial as part of the Hello World series. This looks at creating a simple flow providing protocol conversion from SOAP/HTTP to JMS.
One of the ongoing web service battles is SOAP versus REST (Representational State Transfer). Greg Flurry provides an interesting article showing how to create an “adapter” Java component to invoke a RESTful service from WebSphere ESB or Process Server and how to expose a RESTful interface to an SCA module.
Lastly, Tim Baldwin from the WebSphere Service Registry and Repository development team has an introductory article looking at the EJB APIs to the product. This includes some samples which should provide a good starting point for anyone working in this area.
WebSphere Service Registry and Repository Eclipse plug-in
Wednesday, November 8th, 2006The Eclipse plug-in for WebSphere Service Registry and Repository slipped out last Friday as SupportPac SA02. The plug-in requires an Eclipse Version 3.0.2 or later shell so will work fine with WebSphere Integration Developer and Rational Application Developer. It enables the Registry to be queried, artefacts extracted from the Repository and then these, or other artefacts, published back to the Repository. Properties can be modified on artefacts and relationships added between them. Importantly, unlike the web GUI, the plug-in enables collections of artefacts to be published together without having to worry about the order in which they need to be published.
Message Broker nodes for Service Registry and Repository
Thursday, October 19th, 2006Yesterday saw the publication of a developerWorks article describing the SRRetrieveITService and SRRetrieveEntity WebSphere Message Broker nodes provided in IA9L SupportPac for integration with WebSphere Service Registry and Repository. The first of these nodes retrieves a service endpoint based on a specified port type. The example shows how this can be used with the HTTP input node to dynamically locate and invoke a service. The second node can be used to retrieve the metadata for an arbitrary entity stored in the Registry and Repository. This could be used, for example, to retrieve policy data relating to the service to be invoked.
developerWorks deluge
Wednesday, October 18th, 2006I’ve only just got round to reading last week’s developerWorks newsletter and it contains a positive plethora of interesting articles following the SOA launch.
