The 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.

Wednesday, November 8th, 2006Authentication aliases
Wednesday, November 8th, 2006I had a couple of questions last week relating to authentication aliases. When using WebSphere Application Server resources built on the JCA support, including JDBC data sources and JMS connection factories, there are a number of different mechanisms for specifying security credentials.
J2EE newbies
Friday, November 3rd, 2006Whilst the majority of the customers I deal with are well versed in the ways of WebSphere, just occasionally I come across one that is not only new to WebSphere but also to the world of J2EE. In the past I have struggled to suggest suitable reading material, often resorting to the Sun J2EE tutorial as a starting point. Now Charlie Brown (who, as he hastens to point out, does have a beagle but not called Snoopy) has written an excellent introduction to J2EE the WebSphere way entitled “Experience J2EE! Using WebSphere Application Server V6.1“. It’s currently only a draft but, having taken a look at the messaging section, it’s well written and informative. There is even a chapter covering the, to my mind, advanced topic of importing a subject on to a message-driven bean’s thread using the credentials passed in a message. Be sure to rate the book so that we can ensure that Charlie’s good work can continue.
developerWorks roundup
Thursday, November 2nd, 2006This is my usual weekly roundup of what’s new and interesting on developerWorks. This week we start with something for the WebSphere Application Server developer. When abstracting configuration properties out of code they often end up in a simple properties file. This is fine if the values are static but, if they need updating, you either need to redeploy the application containing the file or else put the file somewhere separate from the application. (If taking the latter approach then the config directory is a good place for the file as then you call leave the application server to replicate it across the nodes.) Perhaps a better approach is to configure a resource environment provider as described in this article, enabling properties to be defined administratively.
High availability of WebSphere MQ link
Tuesday, October 31st, 2006Today sees the release of WebSphere MQ SupportPac MR01. This provides the source for a WebSphere MQ channel exit which can be configured with a list of host names and port numbers to which the channel will attempt to connect. The intention is that this exit can be used when using a WebSphere MQ link to connect a clustered Service Integration Bus messaging engine to a queue manager. The messaging engine can now failover to another cluster member and the queue manager will still be able to connect.
Tax discs online
Friday, October 27th, 2006The DVLA have finally joined the 21st century and I’ve just purchased a new tax disc online. Shame that the big yellow box on the front of my renewal form didn’t contain the required reference number but holds an advert for buying online instead. Fortunately, with the reference number from the vehicle registration certificate and a license plate number it was able to find the necessary records. The system doesn’t quite deliver on the “quickly” part of the advert – only after you’ve paid does it tell you that it may take up to five working days for the disc to arrive. Shame the current one expires on Tuesday!
WebSphere Application Server command framework
Thursday, October 26th, 2006Admin commands and task commands have done much to reduce the complexity of scripting WebSphere Application Server in recent releases, effectively bringing the simplicity of administrative console panels and wizards to the command line. If you find yourself repeating the same administrative actions, this developerWorks article covers in depth how to go about writing your own commands.
WebSphere ESB vs SIBus
Thursday, October 26th, 2006Rachel Reinitz and Andre Tost have kicked off a new developerWorks series on WebSphere ESB with an article describing the relationship between the product and the Service Integration Bus. In my mind, it’s a shame the article doesn’t talk more about about the SIBus Web services support. The following phrase sums up the key difference: “WebSphere ESB is built with the strategic SCA/SDO programming model”.
