Wordpress can expose every category or tag as a RSS feed. For example, you can announce the feed for a category by adding this into your theme file at the part where the HTML-Head is generated:

If Eclipse complains that it cannot start JBoss (”Timeout waiting for JBOSS 5.0 to start. Server did not start after 50s.”) then try to set the timeout to a higher value. It can be done in the options:
Windows -> Preferences -> Server -> Server timeout delay

There are a lot of tips and hints out there on the internet, which describe how you could add support for Java Server Faces and Facelets to the Eclipse environment.
Mostly, they deal with adding code completion for JSF/Facelets tags and so on. There are some possibilities to achieve this, ranging from creating TLD files to using the JSP editor in Eclipse for the XHTML code of the Facelets pages.
But the “trick” I prefer is much more simple 
You want to see it? Well, just download and install the JBoss Tools and you have it all!

Usually, when you enter standard <!-- ... --> html comments in your XHTML definition for a Facelets view, these comments are rendered by Facelets, so they are included in the resulting HTML. Even EL contained in these comments is executed!
In most cases, this is not what you hope to see, because if you want to make real comments, you have to use the <ui:remove> tag, which is not really comfortable.

While the design of a website is already separated from the content by using CSS (Cascading Style Sheets), the scripting features of a website can also be pulled out off the HTML file.

I have recently joined twitter, mostly because of the hype and not because I see any very good use 
All people complain about the stability and I can really understand why. Since I am not using any twitter client currently and their IM Jabber service is still down, I have to use the website. It sometimes loads slow or not at all which is really annoying. I can understand why power users hate that.
What I noticed when searching users from Stuttgart is that users which you already follow are displayed in a different color and have some options aside. So, for every search you do, the database table with the people you follow is checked too. This is of course very nice for usability but if everything in twitter is luxurious like that then no wonder they have issues about their load.
By the way, Sebastian is also on twitter.

You are wondering why your JUnit tests run very fine when you launch them using Eclipse, whereas they all break down when building your project with a build system like Ant or Maven?
Well, thats probably because you are using assert statements and Eclipse per default is not configured to evaluate them.
To solve this problem, simpy go to Run -> Run… -> Arguments, and in the box labeled VM arguments:, enter either -enableassertions or just -ea.
That’s it!

Today, I had some time to spend on my new open source movie collection web application, MovDB2.
I did some thinking about infrastructure, and collected my decisions on the project wiki.
The thing is: Most of these decisions have been done more or less arbitrarily.
I’ll list my available options and my reasoning behind the choice.
The problem I want to highlight is: How do you actually choose the right infrastructure for a new project?

Recently I visited Jazoon, an international conference for Java developers at Zurich, Switzerland.
Having heard a lot of interesting talks, I want to sum up my impressions and try to figure out some of the latest trends in the world of Java as well as interesting facts for software architects.
This is part 4 of my series of blog posts and deals with
Google Android
In his talk about the Google Android platform, Peter Wlodarczak described the experiences he made when developing a mobile application for the new Smartphone OS from Google.
His application is a mobile translator, which is even able to do some OCR in order to translate e.g. Chinese signs.
Developing applications for Windows CE based Smartphones for years, I want to compare the impressions I got from Android to the experiences I made with Windows CE.
