Introduction to Service Oriented Architecture (SOA) by Jagadish Chatarji. Non-technical introduction to the concept of SOA as well as a brief discussion of technologies such as J2EE and .Net.
Introducing JDesktop Integration Components, Part 1 by by Joshua Marinacci (14th October 2004) – An article on the JDIC project, a set of modules that gives Java developers access to native features through cross-platform APIs. JDIC includes:
* Desktop: Launches desktop programs to open, edit, print, and mail files.
* Filetypes: Sets desktop file type associations.
* Browser: Embeds a native web browser (Internet Explorer or Mozilla) into an AWT canvas.
* Packager: Command-line tools for converting Java Web Start programs into native installers.
* Tray API: Support for system tray icons and pop-up menus.
* SaverBeans: System screensavers in Java
Web Analytics Using Oracle Application Server Discoverer, by Timothy Cambier and Brian Carr – published on OTN, October 2004 – describes how you can load Apache log-files into a database structure and then analyze page-visits using Oracle Discoverer. Perhaps a nice workshop for a KC session on Discoverer?

An Alternative Approach to Summary Table Management Using Advanced Queues, by Arup Nanda, Spring 2003; this article describes a way to maintain Summary Tables from changes in detail-tables using triggers and Oracle AQ; in this case, the dependencies were too complex to make use of Materialized Views in Fast Refresh mode and a full refresh took 24 hours. A trigger-only solution did not fly in a multi-user environment. It looks like a custom implementation of what since Oracle 9iR2 is known as Changed Data Capture. The article could serve as an interesting yet straightforward example of using AQ. Perhaps either for a KC or the Oracle 7Up Expert workshop.
Mastering the WHERE Clause (excerpt from Mastering Oracle SQL, O’Reilly). Whether you are querying, modifying, or deleting data, the WHERE clause is the mechanism for identifying what data you want to work with. This chapter explores the role of the WHERE clause in SQL statements, as well as the various options available when building a WHERE clause. It seems introductory, yet useful as a refresher. Perhaps to be used for 7Up or article and KC session on Query Structure.
Animated Tree script + tutorial AnimTree is a menu tree script that features animated opening and closing of menus. You design your tree with valid HTML and CSS and add onclick event handlers to certain elements. The AnimTree script makes it come alive. There’s a structure that you must follow, though. See the tutorial for a more detaied explanation, or download the source code to learn how AnimTree works. Cookie persistence saves the tree state for your users, so the tree will “follow” the user around the site and when the user returns, the tree will be open where he left it. Try it â€” hit reload and watch the menus open.

The Introduction to Service Oriented Architecture (SOA) by Jagadish Chatarji contained an interesting on-liner on the difference between .NET and J2EE. Basically, J2EE is .NET inside out:
Advantage of .NET would be not to depend on OO knowledge as much as the J2EE technology does. On the other hand, J2EE does not imply a so-called vendor lock-in and has a large Open Source community with supporting software.
Moreover, the author expects that neither technologies will prevail the next 5 years. Since Microsoft has always been strong in small and midsized businesses, it’s likely that J2EE will have a larger market share in big companies.
