How eBay uses J2EE to support 1 billion transactions a day

For all those who missed it at JavaOne, here's a link to what I think is a true J2EE success story. The eBay development team discarded a 3.3 million line C++ ISAPI DLL [how much is that in blood, sweat and tears?] to a J2EE-based solution on [hold your breath] WebSphere 4.0 [now exhale slowly]. The presentation is a great testimonial to using patterns, optimizing code and the environment and a plain old good architecture. It requires a quick and simple registration but don't let that put you off. The content is worth it.

  • Hi There,

    Thank you.

    THE PDF presentation was was too slow. I would rather download a real PDF presentation. Do you know if there is a PDF download at all ?

  • When the presentation window opens up, look at the toolbar on the bottom. There's a 'save' icon you can use.

  • Unfortunately, it's not true. eBay tried to go the J2EE route, but it hasn't been a success story. The 3.3 million line C++ DLL has not been discarded, and the productivity of the J2EE developers has been substantially lower than the productivity of the C++ developers. Many of the problems were due to the J2EE patterns preventing reuse and promoting redundant code development -- business objects without behavior, value objects to transfer data between tiers, business logic polluting commands and so forth.
