J2EE
The Servlet specification provides a really elegant mechanism for packaging up a whole website in to a single WAR file and deploying that file as a website. Multiple websites can be mapped to different domain name prefixes, such as 'www.proteomecommons.org' versus 'tranche.proteomecommons.org'. This blog explains a hack to map the domain prefix to a sub directory of the same web application.
This code as been shown many times before, including in my book. This is exactly what the title says: a JSP that will display the request headers sent by your browser. It is also a good example of how to use the JSP EL and the JSTL core tags to make an incredibly simple JSP.
I met Fred and John and they asked about doing clever image manipulation on the client-side, but without requiring the client to run anything but a web browser. It seemed like doing a few tricks with ImageIO on the server-side would solve the problem, and it'd eliminate the piles of JScript they had been working on. Here is the code so that others can easily write servlets that manipulate and generate images.
I'm sitting in on a J2EE training course, and it appears that custom tags are a waste of time. Hopefully you can save them.
Why is it that the first servlet people teach is on that produces static content? HelloWorld.html is appropriate. HelloWorld.java is silly. I'm taking suggestions for the best dynamic, simple HelloWorld servlet idea.
I downloaded your book for free but I need help printing it.
Here is a reply to a really common question. What are the things I should keep in mind when making a secure website? This particular question was from a person who was considering using Java or Python, but the important stuff really doesn't rely on a particular programming language. If you are green, take a peek. If you know your stuff, fill in what I missed.

Hi,
I'm a young java programmer(for now) and on the brink of writing my SCJP1.4 exam I want to be a Java Developer(J2EE) more than anything else. I've picked up REALLY REALLY bad coding conventions and norms along my path to Java-enlightenment and I would like to know from YOU, what could I do to turn this around and become a precision Java Developer, Are there Rules and Guidelines (in ENGLISH) that I can follow that will set me apart as a "developer of note"?

Think the website is cool? Download the source-code for it! Here are two JSP/Servlet websites that you can download all of the code for.
Blarg. I hate blogs.
