Even without huge announcements or great surprises, it was a great conference. Here are my impressions from the cool stuff keynote and my takeaway what it all means.

Details below. J2SE cayhorstmann 2008-05-08T22:57:37-08:00 http://weblogs.java.net/blog/cayhorstmann/archive/2008/05/java_one_day_2_1.html Here is my report from day 2 of Java One. I continue to feel diffident about RIA and Java FX Script, the theme of this year's Java One, so I decided to make my own themes: Ease of development, and transparency. cayhorstmann 2008-05-07T23:30:53-08:00 http://weblogs.java.net/blog/cayhorstmann/archive/2008/05/java_one_day_1.html Here is my braindump from Information Overload Central, AKA Java One 2008. Java FX Script. EJB 3.1. Defective Java. Java Language Evolution. cayhorstmann 2008-05-06T23:35:51-08:00 http://weblogs.java.net/blog/cayhorstmann/archive/2008/05/java_one_day_0_1.html Last year, Java One Day 0 was Netbeans Day, in a cozy hotel. This year, the Java One week started much more grandly, with Community One, at the Moscone Center. My mind wandered during the keynote speech, but I was enchanted by the enigmatically named EclipseLink and robots that had cockroach reflexes and were programmed in GreenFoot.

J2SE cayhorstmann 2008-05-04T21:16:37-08:00 http://weblogs.java.net/blog/cayhorstmann/archive/2008/04/is_computer_sci.html This Washington Post article reports on the elimination of underenrolled Advanced Placement (AP) courses in American high schools. The subjects affected are: Italian, Latin Literature, French Literature and, hold on to your hats, Computer Science AB. This blog tells you what that all means and why it is deplorable.

The talk promised to revisit the classic Feel of Java paper that famously declared “Java is a blue collar language”. I went with my graduate programming language class from SJSU, and here is what I learned.

Many years later, the reality is far from perfect, but are we getting closer? I report how NetBeans, GlassFish, JSF, and JPA worked for me in a recent -h-a-c-k-, erm, agile development project.

Bruce Tate has long abandoned Java for greener (or redder) pastures. Bruce Eckel has embraced Flex , Bill Venners favors Scala. Python is making inroads in college curricula. What is a Java programmer to do? In this blog, I argue that we need to focus on less on syntax and more on the pain points of Java programming.]]> J2SE cayhorstmann 2008-01-08T09:32:12-08:00 http://weblogs.java.net/blog/cayhorstmann/archive/2007/12/the_olpc_and_ja.html I got myself (and another deserving child somewhere out there) a "One Laptop Per Child" for christmas. Here is my experience with Java on the device, followed by some year-end musings what this all means.

Conspicuously absent from this discussion was my pet unappreciated language feature, native properties. Most of the effort about properties has been scattered about in the blogosphere. Nikolay Botev, a CS student at SJSU, did something about that and put together a nifty Wiki, complete with voting buttons.

Today I found this in my inbox: "I'm a reviewer on another track for JavaOne '08, and couldn't help but notice your rather dismissive review of my proposed technical session." The topic is DSLs, and I feel rather strongly that a DSL is best embedded in a host language. If you disagree, let me know and I'll reconsider my review.

This blog entry shows how to carry out this task with the excellent Flying Saucer XHTML renderer and concludes with some ramblings about infrastructure.

Executive summary: 1. Don't rely on JavaDB being present in the JDK. 2. A bungled bundle is worse than no bundle at all. cayhorstmann 2007-08-02T10:48:09-08:00
