Having done a little research on application server shutdown in order to answer a customer query I thought I would post my findings. WebSphere Application Server supports three shutdown modes: stop, stop immediate and terminate (in order of immediacy).

Graceful shutdown
Friday, September 5th, 2008My first US patent
Thursday, September 4th, 2008Last week I had my first US patent issued: #7218708. The patent describes the use of the J2EE Connector Architecture to integrate a Java Message Service provider with an application server. This is something that is actually very easy to do with JCA 1.5 given the restriction of one JMS session per connection introduced by J2EE 1.4. However this patent describes a mechanism to use JCA twice (once at the connection level and once at the session level) that doesn’t require this restriction. This was first used in WebSphere Application Server V5 and continues to be used for the WebSphere MQ and generic JMS provider support today.
Configuring SIB J2SE client with SSL
Wednesday, July 16th, 2008If configuring the service integration bus J2SE client for SSL is a topic of interest to you then make sure you register for next week’s presentation from Rich Montjoy in level 2 service.
Dynamic JMS endpoints
Tuesday, July 15th, 2008In an earlier post I promised an example of where service integration bus mediations still have a role to play in a WebSphere ESB environment. WebSphere ESB currently only supports dynamic endpoints on an import or callout (those that can be changed at runtime by a mediation flow) for SCA and web service bindings. In this post I’ll show how a service integration bus mediation can be used to add dynamic behaviour to a JMS binding.

Mediation handler tooling broken
Tuesday, June 10th, 2008Despite being sidelined by the arrival of WebSphere ESB, there are still times when it is useful to use the mediation support in WebSphere’s service integration bus (of which more in another post). It’s obviously a while since I’ve done it though as apparently the mediation handler tooling in Rational Application Developer has been broken since v7 was released. I’m told that the fix will finally make it in to 7.0.0.7.
Wednesday @ WSTC
Thursday, May 8th, 2008The first slot of the day was one of those rare occasions where I wasn’t quite sure what to attend. In the end I opted for Alex Polozoff’s "Large Topology Tactics and Tradeoffs" presentation as I have great respect for his opinions. The emphasis here was not so much on the technology but the processes and the people. Most of it seemed common sense (at least to me) but the presentation should be a useful resource for anyone embarking on large scale WebSphere topologies.
Web messaging lack of service
Monday, March 31st, 2008Last week I spent a not entirely constructive hour or two with a customer trying to get them started with the web messaging service. This is a component of the Feature Pack for Web 2.0 which provides a bridge between the default messaging provider’s publish/subscribe capabilities and an Ajax (Comet) client. The InfoCenter contains a great quick start guide but it was missing one vital piece of information.

Jython scripting
Monday, January 28th, 2008I’ve had the pleasure of working with my UKISA colleague Andrew Simms on a number of occasions. Some may have been luck enough to see his “Monty Jython’s Scripting Circus” presentation on the conference circuit recently. If not, fear not, as he now has a developerWorks article to set you on the path to being a Jython pro!
