JavaOne - Day3 - Wireless World

I also spent some time talking the the SprintPCS folks after the keynote. If you haven't started paying attention to the Micro edition, here's why you should. Later this summer, Sprint is rolling out a full 3G data platform network. They're going for speeds of 144 Kbps this year, 288 Kbps in 2003, and 3Mbps in 2004. The need for speed has always been here; now finally the way to handle it is arriving. The Samsung A800 and N400 phones are rolling out with active matrix color screens that enable support for multimedia and 3D graphic APIs. Check out the developer's kit on the SprintPCS site. Based on MIDP, Sprint is adding additional network (HTTPS, TCP/IP, SSL) support, Muglet APIs (context handling between applications), and multimedia. The SprintPCS developer program is also getting into full swing with the Vendor Machine model. Build your J2ME apps, upload them to the Vendor Machine (check out JSR-124 for more info), set your own pricing model, and it all can be provisioned on the fly by customers. It was demonstrated this morning, and it also has a private Vault. The Vault can be used to store MIDlets that are purchased so that you don't have to have them all loaded on your phone at once. Find more developer info at developer.sprintpcs.com.
It's good to see that the J2EE/J2ME integration is really taking hold. I walked through a demo on workforce automation with the folks at Interlink who are showing an internal Web services app. Using a variety of clients and devices (J2ME, Palm, Browser, Rich client), they are offering web services that provide presentation services using a variety of application sevices (reporting, alerts, queries) to access various business services. What I really liked about this is that we aren't talking games here. We're talking honest-to-goodness live Web services applications providing useful business models and using all sorts of devices. There are some exciting times coming on the development front for all of us. If your hair isn't standing up on the back of your neck by now, you might want to think about getting another career.
The gadget mania device showcase in the Pavillon also has an array of pretty cool devices including; smartcards, video phones, PDAs, phones. There's been a constant number of techies salavating at the thumb candy behind the casing. Two new VMs (code name Project Monty) for the CLDC and CDC/Dynamic Compiler were also announced today that offer up to 10 times better performance than today's VMs on smaller footprints.
On the J2EE front, some news on upcoming JSP/Servlet happenings. Servlet 2.4 (JSR-154) is looking to be focused on extensiblilty, enhancments to the listener model, session/login managment and consolidation. 2.4 looks to be more conservative then the 2.3 release. The spec is still in the expert group but should be going into public review very soon. Some major highlights include:
On the JSP 1.3 front (currently in Expert Draft), the major goal is to simplify. Key new features include Expression lanaguage (EL) support and Fragments. EL support is actually in the current JSTL, but will be moving into JSP 1.3 due to current release schedules. EL will be available to the JSP and taglibs, as well as template text. There is still talk of having functions supporting in the EL, but it hasn't been decided yet. Fragments will provide a better abstraction mechanism for custom actions (i.e custom tags). It will allow authors to take JSP code and turn it into custom actions without going through the actual process of writing custom tags. This feature should significantly simplify what it takes to make body content and custom actions. Keep an eye out for the community and public reviews for the JSP 1.3 spec and get your input heard in the JCP process.
In the spirt of the wireless mania, OTA and out for today.
