J2SE

So, what was cool this year? The tiger on stage? I missed that. The keynotes that were more or less repeats of the previous year's keynotes? Unfortunately, I didn't miss those, though I wasn't quite as put off by them as some people were. (But I admit--I missed the tiger because I was tired of listening to last year's keynote one more time, so I split.) We've been hearing that "this is the...

I'm up at JavaOne today. As usual, it's a blast. We brought a gorgous baby white tiger on stage to help us kick-off the "Tiger" section of this morning's general session. He was great fun and really mellow. He had got up really early to come to Moscone, so he was quite sleepy by the time he came on stage. He had been more active during our prep session when he was gently play-biting on my...

Linux

At JavaOne, Gosling, Brian Behlendorf and IBM's Rod Smith among others had a discussion about the merits of Open Sourcing Java. Gosling noted that one of the primary benefits of open sourcing the code, compatibility, is served already by Sun support for Java in a consistent fashion across platforms. But that's not really what I feel the need to address, but something else. But first, a link to...

Open Source

Apple's World Wide Developer's Conference was going on concurrently with JavaOne last week. I watched Steve's keynote presentation via Quicktime after hearing tale that one of keywords of the keynote was "search". In the keynote, Jobs unveiled Spotlight, a very clever and pervasive search infrastructure for Mac OS X Tiger. One of my most favorite authors, Steven Berlin Johnson, says its...

Why become an open source developer? I think there are probably as many answers to this question as there are developers. I can only tell you about my decisions. I have been actively developing software professionally for nearly twenty years. I feel, as it is with many of us; it is not only my profession, but also my passion, and my hobby. I delight in learning useful new technologies. In the...

JavaOne

The title of this blog entry was dreamed up independently and before I read Dion's blog entry "The Network Is The Conference". I agree completely with Dion's entry, yet add that it really is bigger than simply the JavaOne conference. In fact, had we all gotten together in the same time-space without JavaOne going on, many of us might not have even noticed a difference. I am, however, very...

The last technical session I attended was about the role of Java in the Mars Exploration Rover mission. Java played a big part in the processing and display of images sent back to earth by Rover's cameras and sensors. One picture was shown of an object sitting in the middle of a Martian crater that looked suspiciously like a bunny rabbit. For some time the scientists puzzled over what it could it...

At a previous job, we developed a Jini-based system to discover and expose whichever of our services were present on a customer's network. This led to a large Jini federation within the company's network, which led to problems as we hopped firewalls to remote points on the WAN. Complicating the matter was the network admins' all-too-typical Stalinist network policies, preferring to lock down...

Today I attended a very interesting presentation by Kevin MacDonald and Larry Mitchell on the use of Jini Network Technology in RFID applications. Goods are tagged and scanned as they move through the supply chain. Often many scans are performed on the same object, resulting in a very high volume of traffic. Kevin and Larry have found that Jini scales well to meet this challenge. This has been a...

Brian Murphy gave an excellent presentation today on the latest and greatest advances added in the Jini 2 Starter Kit. One of the topics was about security features. There are many assumptions that developers of distributed applications make when first starting out. Peter Deutsch has identified 7 of these fatal assumptions in his now famous Eight Fallacies of Distributed Computing (James Gosling...

After a three year hiatus I am once again in attendance at Java One. I am having the same problem this year that I had in years past. So many technologies, so little time. For a computer geek like myself, however, it's a great problem to have. I have decided at least to attend all the Jini technical sessions and BOFs. I used to work in the Jini group. It's great to catch up on what's new and...

Databases

Factory Pattern: Many developers already apply the factory pattern for JDBC connections. The new standard finally applies the pattern, eliminating the need to use the connection manager and some of the code surrounding the connection creation. The connection manager will still exist for backward compatibility. SQL 2003: For the SQL guru’s, the next version will be SQL 2003 compliant...

Community

The Concept Map is an interactive diagram that allows panning, zooming in and out, and resizing. Additionally, the diagram contains links to the technologies associated web page. [This feature makes it easy to find the tech web page.] There is also a quick index of the different Java technologies. Interesting note: The map implementation is in Flash, and NOT JSF, Swing, or some other Java...

Tonight we'll get a look at several of the communities. Don't miss it. Jini, JXTA, Java Community Process, and java.net will all have a chance to give a whirlwind presentation (and prizes), and then you'll get a chance to corral folks about any one you're interested in. Question about JIni? Ideas about JXTA? Complaints about the Java Community Process Just come in, see what's up, get some...

An encyclopedia of Java, javapedia allows everybody in the community to describe the parts of Java technology. The wiki mindset allows developers to get involved in the community by allowing the addition, editing and commenting of entries. For instances, authors and tools developers can add links from the technology described in javapedia to their efforts. Javapedia is an opportunity to become...

My immediate impression of JavaOne 2004 is certainly positive and I have already met some very interesting folks who are using Java innotive ways. Jonathan Schwartz gave an excellent key note this morning and emphasized that the majority of innovation happens elsewhere. More and more I am finding this statement to ring very true. We have been very busy in the JDBC Engineering team over the past...

Click hear to read more about my plans for JavaOne. I'll post slides for both my "Advanced Wireless Programming" tech session and "J2ME at Five" BOF to my site on the day of the presentations, and I'll also be blogging as much as I can throughout the conference on BillDay.com with an end of week summary of important wireless related information to java.net. Hope to see many of your in San...

J2EE

More fun today with JSF, including some discussion of integration with the new POJO persistence systems, and some musings on web services. JSF & JDO I’ve had a chance to play around a bit with Creator, and it looks like plain old Java objects (or POJO) will play nicely. One nice thing about JSF – it knows about collections, which means that Creator can work with them easily as well...

From the very beginning, the JDO specification has been surrounded by controversy. You want drama? Consider the new startup specification against the establishment of relational database vendors and TopLink, the leading OR mapper. You want strangeness? Consider a specification for transparent persistence without any object relational mapping at all. You want a full-out bare-knuckled brawl?...

Games

JavaOne this year is proving to be an exciting and interesting event. Between Hibernate and EJB 3.0, there is a sense that the persistence world is moving toward a more rational, coherent model. Initial skepticism over JavaServer Faces (JSF) is waning in the face of the broad tool and component vendor support. Many developers are warming up to the new features (and understanding the...
