Sun is surveying Java folks about developer demographics and what they want in the 2004 JavaOne conference. If you think it might actually help get Sun to make a better JavaOne show then definitely fill out the survey!

UPDATED: January 23rd, 2004 I've received a lot of mail and seen a lot of postings about this blog entry. Some of it has been supportive and some of it has been …. Well, not. The one thing that is common to all but a few of the responses is that people have misunderstood my point. This is good evidence that I did a poor job of articulating it – something writers struggle to avoid. Anyway, I...

Java innovation continues to have many faces and it not always technical. Matt and Rick of JavaLobby recently invented a new handshake for Java developers to greet one another. I think it's a cool idea and it will be interesting to see if it takes. Check it out in their forum and send in your picture! To Matt and Rick: We love the stuff you are doing over at JavaLobby and would love to see...

This week my team re-learned the debuggers' mantra: "What you think is improbable probably isn't as improbable as you thought.". A horrible performance problem cropped up in an upcoming release of our web-based product last Thursday. Each page of the application would take almost thirty seconds to load. This is not a good thing. Embarrassingly, this problem was hard to track down because we...

James Strachan and others have been working on an awesome new scripting language for Java called, Groovy. I met James at the ApacheCon conference last year and he made me a convert to Groovy – its really a beautiful language and fairly easy for Java developer to learn. What makes Groovy really cool is that it integrates seamlessly with Java programs and is actually compiled into Java byte code....

Data Abstractions are wonderful things, except when they aren't. A recent request from my QA team lead brought me to this not-so-stunning conclusion. The request was pretty simple: "Tell me which fields in our database correspond to the input fields on our HTML forms." This is a very reasonable request. My QA team wants to initialize our relational database with a specific data set, verify...

Check out my Artima blog entry, Deconstructing the Cmabirgde Uinervtisy Rschereach Sramlcbe, wherein the wild meme: Aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht the frist and lsat ltteer be at the rghit pclae.

I was going to blog about Date and Calendar (and how terrible they are), but these must wait now. Straight to the point: if you want to get J2SDK 1.5.0 alpha, just go to: http://www.javalobby.org/members/j2se15.jsp This is a cooperation between JavaLobby - hey, just became a member 3 weeks ago, after years of Java, can you believe it? - and Sun. This is really a private release, so, you are not...

Greg Wilkins, creator of the open-source Jetty servlet engine, spouts off in his blog about why he thinks that Servlets must DIE! Slowly!! It's hard to argue that the servlet specification isn't full of cruft and that the servlet expert group of the JCP should take a major refactoring approach for the 3.0 version of the Servlets specification. However, does Greg's notion of "Contentlets" make...

Like Joshua Marinacci How do you develop?, a number of programmers, including myself, have adopted a fairly iterative development style. For the most part, this has been a conscious decision. However, there are times when this isn't always so. Occasionally, the style has more to do with the nature of the work than with the desires of the developer. I was recently preparing for a short...

Joel Spolsky, of "Joel on Software" fame has posted a new essay called "Biculturalism", which is a review of the book The Art of Unix Programming by Eric S. Raymond. (If you prefer bits to atoms, you can read the whole book online for free, Eric being a famous Open Source advocate.) [One digression: Follow that link to the book above. You will find yourself on a great website for books: Amazon...

We're going festive at this month's London Java Meetup with our Christmas party on Monday, 15th of December. The full details are available here, but essentially it's a change of venue and there may even be some cross-technology fertilisation as we mingle with some of the London Perl Mongers. This event is open to anybody and if you're planning to come along, please just leave a comment. If...

We often hear George Santayana's adage: "Those who do not understand the past are destined to repeat it" Study history or you're going to screw up. Good advice, but rather on the negative side of the Kharmic spectrum. Less often do we hear Sir Isaac Newton�s more positive sentiment: "If I have seen further it is by standing on the shoulders of Giants" Newton's adage is the one that came...

A Microsoft wonk asked me an interesting question yesterday: Will IBM and BEA make the Java Community Process obsolete? The impetus for this question was the recent release of three J2EE "specifications" by IBM and BEA, which you can review here. Rather than develop these specifications from scratch within the JCP process, as is done in many cases, IBM and BEA decided to propose three new JSRs (...

I have just finished writing up my interview with the well known Java celebrity Richard Monson-Haefel. It was a fun piece to do and I asked him many Java questions including his recent appointment to the JCP Executive Commitee. One of the refreshing things I discovered was that Richard wasn't scared to point out Java's weak areas and wasn't one of the gung-ho bridgade that thought everything...

I've spent the past week reaquainting myself with JMeter to do some quick-and-dirty load testing for one of our web-based applications. Since I want to simulate many simultaneous users, I want to parameterize my test script to provide different login values for each user. One way of doing this with JMeter is to add a “User Parameters” element to my “Thread Group” and use the ”_StringFromFile...

In Sue Spielman's Practical JSTL article, she writes: The JSTL includes a number of actions that provide a mechanism for interacting with databases. The previous sentence should, at a very minimum, send up a red flag in your architectural visions. One might ask, "Do I really want to be able to perform SQL actions such as queries, updates, and transactions from my JSP? Isn't that business logic...

The TechnoTourette blogger writes I don't want to hear about it Mr. dotnet and that got me thinking about how Sun and so many Java folks react to the dreded "Evil Empire" that is MS. Is the incessant chatter about Microsoft and it's products by various Java "celebrities" just a sign of an inferiority complex or is it a manifestation of a completely rational fear?

As I said in my previous weblog, more J2EE-related JSR final releases would be announced soon. And here they are: JSR 112 - J2EE Connector Architecture 1.5 JSR 152 - JavaServer Pages 2.0 Specification JSR 153 - Enterprise JavaBeans 2.1 Specification JSR 88 - J2EE Application Deployment (maintenance release) NOTE: if eventually more of those JSRs are released today, I will update this blog (...
