Yet Another MVC Framework
WebWork - WebWork is a web application framework for J2EE. It is based on a concept called "Pull HMVC" (Pull Hierarchical Model View Controller). The basic idea is to separate the site programmers' and site designers' tasks.If you've got pointers to WebWorks articles, postings, threads, etc. please send me a couple.It has a small API and easy to use tag library in order to make it as easy to use as possible. It supports the notion of actions that are just JavaBeans. This means that they have setX() methods for incoming parameters, an execute() method to perform the action, and getX() methods to retrieve the result data. This ensures that all actions only contain the code that is required to perform the logic.
The tag library has also adopted this philosophy. They only provide tags to extract and iterate over the result data so that formatting the output as HTML, WAP, or what ever is as straight forward as possible.

OSCache does not require JSP
OSCache includes a caching Servlet Filter. The CacheFilter automatically generates a cache-key based on incoming request parameters and either pulls the corresponding entry from the cache or runs the request. So, adding OSCache to your webapp can be as simple as dropping the OSCache jar in your classpath and adding a Servlet Filter entry to your web.xml.
I had to do a little more work than that because I need to cache on a per user basis and the auto-generated cache-key does not consider request.getUserPrincipal(). So, I had to write my own Servlet Filter based on CacheFilter. Also, CacheFilter is not very well documented, so I had to look at the source to figure it out.
Spotted JState
Spotted JState which looks interesting. It could be useful when putting together an open source workflow system. James StrachanJState does look nice. JState is currently at Revision 0.2.1 and licensed under the LGPL.
Without a net
I really like this idea of using unit tests as a safety net for development, so I guess I need to learn more about JUnit and the Extreme Programming ideas behind it. Up until now, Roller development was done without a net.Sometimes you just won't feel like writing tests, especially at first. Don't. However, pay attention to how much more trouble you get into, how much more time you spend debugging, and how much more stress you feel when you don't have tests. We have been amazed at how much more fun programming is and how much more aggressive we are willing to be and how much less stress we feel when we are supported by tests. The difference is dramatic enough to keep us writing tests even when we don't feel like it. JUnitTest Infected : Programmers Love Writing Tests
Redhat does J2EE
Red Hat CMS [Content Management System] is delivered with the source code and is J2EE compliant, allowing easy extensibility and customization of the implementation by Red Hat, or by the organization's own developers.Excellent! I'll add that to <a href= "http://rollerweblogger.org/page/roller/20020618#a_href_http_radio_weblogs2"> my list of open source Java CMS sofware. The license sure looks like open source.

JDO vs JDBC
you need to decide whether you want an object model for your application or not. If not, use JDBC, if you do, consider JDO.David Jordan of Object Identity following-up his talk on the Triangle Java User's Group mailing list. FYI: Roller uses Castor JDO, which is quite different from Sun's JDO.
Over the wall
Java trivia: some consider Visual Cafe to be the first Java IDE, but I think that distinction belongs to Rogue Wave's JFactory - which was introduced in January 1996 and has since disappeared into oblivion (along with the zApp C++ GUI library).
Open source Visual Cafe?
The deal will also means WebGain will halt all development and sales of its market-leading IDEs Visual Café and WebGain Studio - the latest version of which is currently in beta. WebGain hopes the IDEs will be picked-up by the open source community, carrying the product forward.From The Register's May 6th article WebGain to exit tools, Oracle to buy TopLink. If the above quote is true, it means there will be three major open source IDEs (I'm assuming that Visual Cafe and Webgain Studio are really the same thing): Netbeans, Eclipse, and Visual Cafe. And four if you count jEdit.
Udell: Eclipse is hot stuff
It's true that SWT is not yet available everywhere. But Eclipse 2.0 works with Windows, Motif, and GTK+ (Gimp Toolkit) 2, and operability on Mac OS X seems imminent. Unlike Swing-based software, Eclipse works immediately with native features such as Windows XP skinning. "Microsoft has lots of programmers and so does Gnome/GTK," Grindstaff says. "So why not leverage that?"From a very interesting InfoWorld article on Eclipse via Sam Ruby. I prefer Swing, but if the Eclipse SWT approach means that vim could be embedded into the Eclipse IDE then Eclipse will be the IDE for me. I need to download the Eclipse 2.0 beta and take it for a spin.
Intalio stops support for OpenEJB, OpenJMS, etc.
