Aggregation isn’t currently one of the capabilities available out of the box with WebSphere ESB but it’s something a number of people have asked me about in the past, particularly those from a WebSphere Message Broker background. I was therefore particularly pleased when Russ Butek showed me a draft of a developerWorks article he was putting together which demonstrated how to achieve aggregation using a custom mediation primitive. Looks like that article has now been published so you can now read all about it for yourselves.

Aggregation with WebSphere ESB
Friday, August 17th, 2007JMS connection pooling
Thursday, August 16th, 2007I’ve mentioned one of my colleague Paul Titheridge’s articles before (on JMS Application Server Facilities) and he’s just started a new related series which is well worth taking a look at. This time Paul has turned his attention to the myriad of connection pool properties provided by WebSphere Application Server and what they mean when using WebSphere MQ as the JMS provider. As before, Paul has provided some thoroughly worked examples to help explain the implications of changing different values.
Rails Overview: View
Friday, July 20th, 2007Having covered the Model and Controller aspects of Rails in previous posts, that really means it has to be View next. I’ve already touched on the basics: the controller method renders a template, either explicitly or simply by exiting and allowing the default template for the action to rendered, and the attributes of the controller class setup by the action method are then available to the template.

Connecting Enterprise Applications to WebSphere Enterprise Service Bus
Friday, July 20th, 2007Andrew is plugging the draft of his Redbook Connecting Enterprise Applications to WebSphere Enterprise Service Bus over on SOA Tips ‘n’ Tricks and rightly so as it’s well worth a look. If you thought that WebSphere ESB was just about SOAP/HTTP then this book should set you straight. It covers details of integration via WebSphere MQ, JDBC and HTTP and connecting to CICS. I’ve been working on the labs for the corresponding ITSO Workshop rolling out later this year.
Gallery rewrites are back
Monday, July 16th, 2007Many thanks to Ilya Azarov who answered my plea for assistance and supplied his nginx rewrite rules for Gallery2. I won’t claim to understand why his work and mine didn’t (although previously I wasn’t aware that you could nest location directives so that was something I hadn’t tried). They still can’t cope with spaces in file names but I can live with that.
VMware Converter
Monday, July 16th, 2007I’ve had a nice shiny T60 on loan for the past couple of months for a project I’ve been working on. Unfortunately the time came to return it, at which point I thought I’d try out the free version of VMware Converter. This enables you to take a physical machine and convert it to a VMware image. The idea was that I would create an image of the laptop before giving it back in case there was something on it I still needed.

Changing servers
Friday, July 13th, 2007So, it’s been a little bit quiet on this blog for the past few days. The main reason is that it’s been on the move from the hosting provided by our ISP (PlusNet) to my SliceHost slice. Things would have been much quicker had I not decided to switch Apache for the increasingly popular (due to its low memory usage) nginx.

IBM Resource Adapter for JMS with WebSphere Application Server
Thursday, July 5th, 2007I’ve mentioned the IBM Client for JMS on J2SE with IBM WebSphere Application Server on a couple of occasions. As the name suggests, this provides you with a couple of JAR files that allow a standalone J2SE application to act as a JMS client to the WebSphere Application Server default messaging provider. What it isn’t good for, is acting as a client from another, third-party, application server. Yes it may work but you don’t get all those good things that an application server provides, like XA transaction coordination and parallel message consumption using MDBs. Enter the IBM Resource Adapter for Java Message Service with WebSphere Application Server which allows you to do just these things. Note that it’s currently only tested on Apache Geronimo V1.2 and WebSphere Application Server Community Edition V1.1 but it’s a JCA 1.5 compliant resource adapter so should work with any J2EE 1.4 application server. Also note that, as with the original client, this download is initially only available with an early access license. If you are interested in using it in production though, drop a note to the e-mail address in the technical support section.
