I've decided to publish links to the most interesting blogs, articles and pages that I've stubled upon in a particular month. Enjoy the first dose! (In no particular order.)

I recommend the post 43 Essential Controls for Web Applications,which presents - with screenshots and short descriptions - the most used and useful javascript/ajax widgets for web pages, from the basic ones like auto-complete/suggestions and sliders through a calendar for less known yet very cool ones like sparklines. Read it to learn what's hot and you shouldn't miss in your application! (Warning: The number of widgets on a page is inversely proportional to its quality.)

Colin Eberhardt, the co-author of the Simple Logging Facade, has written a very good article The Art of Logging, which should be a compulsory reading for every developer especially in the server side development domain. It's good both as an introduction as it covers all the important aspects and also for experienced developers because it has some very valuable insights.

Few ideas and sentences that really should be stressed:

If you have an open-source project and want it published into the Maven Central repository - even if it itself isn't build with maven - to make it visible to all Maven users without any special effort (at least once you set everything up), read on.

The book Portlets in Action being written by Ashish Sarin, which I've already mentioned and which looks really promising, has been made available via the Manning Early Access Program. As of today there are two chapters available and you can read the first one "Introducing Portals and Portlets" for free.

What I find to be the most attractive features of this book is that it concentrates on the "new" JSR 286 also known as Portlets 2.0 and goes beyond teaching portlets with its intorduction of Spring MVC and Ajax libraries suitable for portlets.

PatternTesting is a mature open-source project that enables you to automatically check at the compile- or run-time that architectural/design/implementation decisions are implemented and bad practices avoided in the code. The main differences from tools like FindBugs and PMD are that you can implement tests spanning multiple files (classes) and that aside of compile-time checks there are also run-time checks (using AOP with ApsectJ) to do things like "ensuring that there are no more than 10 calls to the database per user case" and providing better error messages in the case of e.g. IOException.

For a long time I've been looking for a web framework that would ease the development of web UI in portlets. Pure JSP is too old-fashioned and the abstraction it provides is just too low-level. There are many good web frameworks for standard web applications (JSF/Seam, GWT, Struts 2, Wicket, you name it...) but if they include portlet support than only as an after-thought and it's usually far behind the quality and features of the standard web framework. Nobody was able to recommend me a decent portlet web framework - until recently.

 First I've learned about an upcoming book Portlets in Action (preview) by Ashish Sarin, which teaches not only Portlets 2.0 (JSR 286) but also other must-haves for a real world development like a portlet web framework and Ajax (DWR in this case). You've surely already guessed that Ashish uses Spring Portlet MVC, which indicates that it must be indeed good.
