Alphaworks has a new tool available for checking out a JMS messaging system.
I talk about it on my wiki in IBM Client Application Tool for JMS.[Read More]
Bobby Woolf: WebSphere SOA and JEE in Practice
From archive: October 2006 X
I'm at WebSphere Technical Exchange.
Eric Herness, IBM's Distinguished Engineer in charge of the WBI suite of products (WebSphere Process Server, etc.), gave two related talks that preview the 6.0.2 releases that are due out in December:
10/31/2006 Update: Like Shaker comments, also check out the WBI 6.0.2 announcement: IBM WebSphere Enterprise Service Bus, WebSphere Process Server, and WebSphere Integration Developer V6.0.2 — the SOA platform for service mediation and orchestration.[Read More]
This week, I'm at WebSphere Technical Exchange.
The keynote was Service Oriented Architecture: The Evolution of an Industry. I've got a transacript at WebSphere Technical Exchange 2006 Keynote.[Read More]
I have a new article on developerWorks, "Running a standalone Java application on WebSphere MQ V6.0."
It's an update of my previous article, "Developing a standalone Java application for WebSphere MQ," which was written for WMQ 5.3. For this version, I have as co-authors T. Rob Wyatt and Kulvir Singh Bhogal; so to the extent this article is better than the first one, give them the credit.
I hope you'll find it useful for learning about JMS and JNDI and how they can be used in Java SE (not just Java EE), as well as how to admin and configure WMQ.[Read More]
I'm at OOPSLA. An especially interesting talk yesterday was Scale Changes Everything.
Linda Northrop of the Software Engineering Institute spoke about Ultra-Large-Scale (ULS) Systems.
Her concern is that extremely large systems we use throughout life, such as air traffic control and healthcare, are becoming more software-intensive and our techniques for developing, maintaining, deploying, and keeping running such software isn't scaling, so new techniques are needed. If developing a really large system is like creating a big building, and a system of systems is like a city block of interconnected buildings, then a ULS is more like a city--and techniques for building buildings don't scale to cities. Cities defy central planning, must keep running constantly even while parts are taken off-line and repaired or replaced, and problems like fires must be contained and avoided until remedied.
In the panel that followed, The Ultra Challenge: Software Systems Beyond Big, Gregor Kiczales observed that these may be problems with developing applications of any size, but that they become completely unmanagable when the system gets so large. Panelests compared a ULS with a nation's economy, emerging from the behavior of lots of separate components acting somewhat independently.
OOPSLA has a wiki page on Linda's talk.[Read More]
When will the next version of WAS be available? When will WAS support Java EE 5?
I can't say definitively, but Dr. Dobb's has some commentary on when the major application server vendors plan to release Java EE 5 versions: "App Server Powers Race To Embed Java EE 5 Support."
The article quotes Mark Heid, one of IBM's Directors of the WAS product, on plans for the next major WAS release. The article also talks about the WebSphere Software Early Programs for adding new features to WAS before the next major release is available, including plans for a feature pack for EJB 3.0.[Read More]
Here's an interesting bit of news: IBM is suing Amazon for patent infringement.
The suits say Amazon violates IBM patents covering such features as allowing users to order items from an electronic catalog, displaying advertising in an interactive service and storing data in an interactive network.
[IBM claims that the patents cover] the presentation of applications in an interactive service, the storage of data in an interactive network, the presentation of advertising in an interactive service, and the ordering of items from an electronic catalog.

I'm at OOPSLA 2006 this week.
On Saturday, I attended PLoP 2006, a separate conference being held in conjunction with OOPSLA this year. I participated in a writer's workshop that reviewed a couple of interesting pattern languages being developed. A lot of people at PLoP this year have never been to PLoP before; it's good to see so many new people getting involved.
On Sunday, I attended a workshop on EDA. We discussed several topics:
Today, I'm attending a workshop on SOA and web services. I'll talk more about that tomorrow.

Trying to understand the big picture about what Java is? (Me too!)
One of the hubs on my wiki has become Java Technologies, which is a start at documenting Java and its constituent technologies, plus related practices like the JCP. Nothing astonishing here, but if you're trying to figure out the main ideas in the Java universe, this is a good place to start.[Read More]
There's a photograph I've seen several times on the news lately that I find really interesting.
It's a satellite photo that shows the Korean peninsula at night. South Korea is all lit up; North Korea is dark. It shows quite graphically that North Korea is not doing well at all. (According to the news, the photo is from a US Department of Defense satellite and has been released publicly.)
Here are a couple of pages that show the photo:
In general, I'm interested in statistics and graphics of statistics:Read More]
IBM has reported earnings for last quarter. I'm no expert, but they seem pretty good.
Who knows? IBM may help the Dow reach 12,000.

The calendar for U.S. Daylight Savings Time is changing in 2007.
The Energy Policy Act of 2005 changed when daylight saving time (DST) begins and ends in the United States, starting in 2007. This could be the Year 2000 Problem all over again. As discussed in "Daylight-saving switch may cause tech woes," lots of electronics from VCRs to Microsoft Windows ("Preparing for Daylight Saving Time changes in 2007") calculate DST and will need to be patched.
The problem affects Java, specifically the JRE, and the apps that run in Java and depend on the current time. See "U.S. Daylight Saving Time Changes in 2007."
IBM has a number of support documents on how to handle this problem:
Apparently Australia has/had a similar problem in 2006: Eastern Australia: Fixes available for Java applications that are impacted by the change to daylight savings time dates (Reference #: 1232128)
Nov 7 Update: Guy Bowerman addresses the DST issue for other IBM SWG products in Extended daylight savings time - should Informix DBAs care?[Read More]
