Java Desktop

Versioning, which I'm defining for this entry as how a Java application manages its external library dependencies, has been a tough issue ever since Java first released. Back when Java was born, the vision was that each machine would have a single Java runtime and standard libraries which would always be fully backwards-compatible. The reality has been that for most apps, the only reasonable...

It's been a long, fun, and exhausting week. I'm going to get some sleep and vainly try to take a flight home tomorrow. Since I'll be there for hours, most likely, this will give me time to write proper entries about the second half of the week and how the conference went overall. In the mean time, our book Swing Hacks is finally shipping on Amazon and we've hit almost #3000. (as of this evening...

It's JavaOne 2005, Monday afternoon, and I'm drifting around Sun's booths on the tradeshow floor. Moscone's meeting halls are two stories tall and underground; it's a basement palace. The cavernous space used by the tradeshow Pavillion must be a quarter of a mile long and a hundred feet high and it's abundantly and artificially lit. It's like being in an aircraft hanger that's inexplicably...

i've been enjoying some of the desktop talks at javaone this week. with swing, a common theme for a talk is: tips and tricks to make swing run faster. so some of these talks got me thinking.. so here's a problem: the construction of swing components is an expensive operation. if you're building a fairly dynamic ui in swing, one where you create views on the fly, as a response to...

I promise I won't shill too much, but Chris just told me that our book was the number 2 seller yesterday according to the list posted by the book store! To our readers we send a heartfelt thanks! - Josh

Open JDK

JavaOne is always a huge buzz, and this year was no exception. Of course the technical sessions are very worthwhile, so it's great news that slides and audio for all of them will be available free online. In previous years you had to pay a small subscription fee to access them. But the biggest plus of JavaOne, like any conference, is meeting people with common interests. I brought back a...

Java Web Services and XML

Based upon the discussion in FI project, I created a new sample that starts with a doc/lit WSDL. I tried this sample with Tomcat container and JWSDP 1.6. Configuration file (Download in conf/Catalina/localhost directory) Zipped directory (unzip in jaxrpc/samples directory) As with the other sample, build target builds the WAR file and run-client target build and runs the client. This...

To highlight the savings in generated code with JAX-WS 2.0 compared to JAX-RPC 1.1, I ran the WS-I Sample application WSDL files through JAX-RPC's wscompile and JAX-WS's wsimport. The results are very good. JAX-RPC 1.1 generated 128 files that were 365KB in size. JAX-WS 2.0 generated only 61 files for a total size of 83KB. That is a 52% reduction in the number of files generated and a 77%...

I thought that a session title that had the phrase "Hitchhicker's Guide" in it would draw a good audience, but I had no inkling of the crush of humanity waiting to get into the session "A Hitchhiker's Guide to SOA: Orchestrating Loosely Coupled J2EE Services with BPMN and BPEL." It felt like Times Square at New Year's Eve. This was worth the mob scene. I know a few things about SOA,...

Embedded

This online article by by Mukesh Lulla, TeamF1 is a pretty good overview of the top 10 misconceptions about embedded security. It's worth mentioning here for a couple of reasons. One: embedded security is increasingly important as more embedded products are provided with a network connection to the outside world. Two: it's generally accepted that the various Java security packages are "better"...

Java Enterprise

With Sun's decision to "Open Source" their Java EE app server, it's likely that all Java EE app servers will soon be free. JBoss, JOnAS, Geronimo and Sun's GlassFish are going to exert huge pressure on the holdouts IBM, BEA and Oracle. IBM and BEA are already formulating responses, as is witnessed by the announcements of IBM support and BEA support for Geronimo, but it's hard to believe that...

It has been pretty exciting after Sun's Open Source Application Server project GlassFish announcement on Monday morning at JavaOne. James Gosling wore our cute GlassFish t-shirt on stage during the General Session on Tuesday. I was glad to see that many developers came to our booth and shared excitement of the news and interests. We had a well attended GlassFish BOF on Monday night to...

Sun Java System Application Server Platform Edition (PE) 9, slated to be open-sourced by Sun soon, is now in development. The product will be integrated with the NetBeans IDE and includes Java Enterprise Edition (EE) 5. Check it out at the GlassFish Project on java.net. First download the binary and deploy an application. Better yet, build GlassFish from square one and contribute to its...

I'm in the Grizzly Tech session, and at the end, they're showing some performance numbers. For a dynamic content, servlet oriented, non-trivial task, the numbers that they've found show that an all Java NIO implementation will beat out a mixed Java-C implementation. (They tested two.) Mixed implementations are the kind found today in things like mod_jk and Sun's Web Server (though they wouldn't...

Mac Java

Apple offered two surprise BoF's at JavaOne - a "surprise" because they hadn't previously been announced or expected and just appeared in the addendum and corrections to the JavaOne show schedule. Still, about a hundred developers managed to find their way over to the Marriott to see the show. I got there too late to see the formal introductions on the first presentation, which was well into...

NetBeans

OK, I got your attention. Now, can we just forget this horse-race and go back to getting some actual work done? No? Oh, fine. So, JavaOne just ended, and everyone's talking about the buzz around these 2 products. There's enough hype around here to stuff a turkey. I saw an interesting post on ZDNet after JavaOne. It was yet another log on the Eclipse vs. NetBeans fire. The content essentially...

To wrap up my JavaOne experience, I went to a pub with Tim Boudreau and my co-speaker Jaroslav Tulach. Over the first few drinks, we brainstormed about ways to simplify/embellish the Actions API When we got a little too drunk for that, we started in on the source code to my FeedReader. We hacked around until we figured out a way to embed a JDIC browser in a TopComponent. That was cause...

I leaned over to Tim Boudreau, NetBeans evangealist, and said, "Boy, wouldn't the bloggers love to get a picture of this." I couldn't tell if he looked amused or worried. The picture I was referring to was the two people sitting next to me. They were NetBeans Platform architect Jaroslav Tulach and Eclipse Platform architect Jeff McAffer. Disclaimer: There's NOTHING going on behind the scenes....

I just finished up an article on NetBeans Day for the JavaOne Today, the conference's daily newsletter. It was fun trying to sound like a newspaper reporter, but now I want to reinsert my own voice into the proceedings, and I'll start with one word. Wow! There were the announcements (collaboration plugins, Matisse, new refactoring) and the stats (550 people or so attending according to Greg...

Java Tools

Today, the ubiquity and versatility of the Internet lends a viable and convenient medium for companies to provide services to each other on the Web. Examples abound: purchases of parts and materials, administration and investment of employee 401(k) plans, travel and hotel bookings. The first and foremost requirement for setting up those interactive transactions is security, that is, verifying...
