Welcome!


In browsing around the Web, as one occasionally does in a free nanosecond, I read an interesting article about twp-phase commit transactions by Gregor Hohpe of ThoughtWorks ('Your Coffee Shop Does Not Use Two Phase Commit'). Gregor comes at the subject from the direction opposite the o...
As I write, the noise level that continues to be generated around open source application servers and their claims to be coming into the world of enterprise computing continues. In my view, the main reason why the noise travels so far and seems so loud has nothing to do with the realit...
This issue, in an uncharacteristic attempt to fit in with the Zeitgeist, I propose to depart slightly from my well-trodden path to the transaction manager and take a look at frameworks. I expect you can guess which particular framework I am going to take a pass at, too. For nearly as l...

Whatever your innermost feelings about the symbols, and however fondly you remember debugging network infrastructures with nothing more than a LAN sniffer and an uncanny ability to interpret 4k blocks of hex, it is fairly safe to say that Web services are here to stay. With the indust...
Another discussion based on a weblogic.developer.interest.transaction posting this month. It's a newsgroup that always proves to be a good source of information for the world at large when it comes to transactional behavior (and a good source of inspiration for me when the article time...
