How Portable Is LWUIT? How Portable is LWUIT? Very, according to Shai Almog, who writes, "LWUIT is remarkably portable, from small CLDC cell phones to CDC hi-definition devices through Swing applications it can do it all. Well, over a weekend a few weeks ago I got LWUIT working on Android, this is still a pretty rudimentary port and it suffers some problems but this is a cool proof of concept...". In a followup, he shows off LWUIT running atop Max Mu's port of Java ME to the PSP.
Open Standards vs Open Source?

GlassFish v3 Now Embeddable
Kohsuke Kawaguchi reports that GlassFish v3 just got embeddable. "I can now run Hudson in this embedded GFv3. Here's how it works — GlassFish v3 can be run as an OSGi application as Sahoo reported earlier, but in fact it can also be run without any kind of classloader isolation system at all. Sure, you won't get the isolations, but this means you can just drop a bunch of GFv3 jars in your classpath and run it like that."
"NetBeans IDE 6.1 supports a wide range of open source scripting technologies and offers improved performance. This release extends language support beyond Java technology by providing a rich set of features for C/C++, JavaScript and the Ruby language, including Ruby on Rails.

Remember, none of this has been finalized yet. All of this is really just a peek into the inner workings of the JCP so that you have a chance to provide feedback."
JavaWorld article on Wizard project
JavaWorld takes an in-depth look at the Wizard project in Open source Java projects: The Wizard API. "If you're faced with creating a Swing-based wizard from scratch, you'll want to know about Tim Boudreau's Wizard project. This installment of Jeff Friesen's Open source Java projects series gets you started with the Wizard API and concludes with a hands-on installation wizard that is sure to please users and impress the boss."
Compatibly Evolving BigDecimal
Joe Darcy continues a recent run of blogs discussing the specifics of what it means for changes to be "compatible" with a case study: Compatibly Evolving BigDecimal. "Back in JDK 5, JSR 13 added true floating-point arithmetic to BigDecimal, which involved many new methods and constructors along with new supportingclasses in the java.math package. I was actively involved in the JSR 13 expert group and integrated the code into the JDK. These changes had some surprising compatibility impacts which can be classified according to their source, binary, and behavioral effects."

Book Chapter: Java EE 5 Development with Glassfish: Security
TheServerSide has posted sample chapter from David Heffelfinger's book, Java EE 5 Development using Glassfish. In Chapter 8, the author covers how to secure Java EE applications by taking
advantage of GlassFish's built-in security features. Topic include security realms, the specifics of the admin, file, certificate, and JDBC realms, creating self-signed security certificates, and building custom realms.
TrackBot Sensor Evaluation
The newly-unveiled Trackbotcode project provides runtime libs, example and test code for Systronix TrackBots. It's a "PC-based application which connects to TrackBot through a DCE serial adapter and enables testing and characterization of all eight IR sensors on the TrackBot platform. It includes a screen-based text/graphical display of sensor response in all three sensitivity settings. Command line parameters include which pair of the eight sensors to test at a time. The code reports any errors and timeouts, and has been very useful in analyzing PC serial port performance."
Updated GlassFish Roadmaps
Eduardo Pelegri-Llopart has posted some Updated GlassFish Roadmaps. "Anybody that has been in the software industry for any time knows that roadmaps are always "work in progress".
With that caveat, here are the latest news:
JBrowser project
The JBrowser project hopes to implement a modern web browser using java swing, with a goal of being "fully compatible with current mainstream browsers", learning from other browsers how to deal with broken web pages. Ultimately, the project owners hope to evolve the project into an RIA platform along the lines of Flex. For now, check out an early snapshot build, with initial CSS/HTML/XHTML, JavaScript, and (J)applet support.
Using Filters With the Java ME Device Matrix
The latest SDN Mobility Tech Tip is about Using Filters With the Java ME Device Matrix. "Let's say you have a design for a mobile application, and you know what technology (JSR) is required by the platform. You then want to know: What handsets will support your design? The SDN Device Matrix is a table that lists information on hundreds of devices that run Java ME technology."
NetBeans Community Greenlights 6.1
NetBeans QA is announcing that the NetBeans Community has approved NetBeans 6.1 for FCS. "We are pleased to announce the results of the NetBeans IDE 6.1 Community Acceptance Survey that ended April 16th: 91% of respondents agree that NetBeans 6.1 is stable enough to move into FCS! (A few respondents recommended that we fix some more issues, and we will try to deliver the fixes via the Update Center as soon as possible.)"
JT Harness 4.1.3 milestone release JT Harness, the general-purpose testing harness, has announced its 4.1.3 milestone release. This release supports JUnit tests and test suites, and includes numerous bug fixes. "JT Harness 4.1.3 provides complete backwards compatibility with previous releases of JT Harness, and JT Harness users will be able to easily migrate to this release. Additionally, the JT Harness 4.1.3 release (and subsequent releases) are covered under the GPL 2 license plus Classpath Exception." More details are available in the 4.1.3 README.
OpenJDK: Dude, Where's My Changeset?
Kelly O' Hair discusses using a Mercurial "forest" of repositories and how changesets come out of that process in his new blog OpenJDK: Dude, Where's My Changeset? "Sometimes it's hard to find a changeset. Somewhat independent of the changesets flowing into the various team areas, the Release Engineering Team will use the Master area and attempt to create a promoted build, and if successful will create tags in the Master repositories to record what changesets were included in a promotion. Some people will find this whole process frustrating, but there are some big advantages. "

Working with jMaki Events
The latest SDN Enterprise Tech Tips looks at Working with jMaki Events. Author Carla Mott writes, "the following tip expands the discussion of the event mechanism in jMaki. You'll learn more about the concepts that underlie the jMaki event mechanism and how to take advantage of it to easily interact with widgets. "
Kinds of Compatibility: Source, Binary, and Behavioral
What does it mean for changes to be "backwards compatible" with previous versions of Java? Joe Darcy clarifies common misperceptions in the blog Kinds of Compatibility: Source, Binary, and Behavioral. "When evolving the JDK, compatibility concerns are taken very seriously. However, different standards are applied to evolving various aspects of the platform. From a certain point of view, it is true that any observable difference could potentially cause some unknown application to break. [...] Since not making any changes at all is clearly not viable for evolving the platform, changes need to be evaluated against and managed according to a variety of compatibility contracts."
Method Handles in a Nutshell
"One of the biggest puzzles for dynamic language implementors on the JVM, and therefore for the JSR 292 (invokedynamic) Expert Group, is how to represent bits of code as small but composible units of behavior. The JVM makes it easy to compose objects according to fixed APIs, but it is surprisingly hard to do this from the back end of a compiler, when (potentially) each call site is a little different from its neighbors, and none of them match some fixed API." John Rose takes a swing at addressing this problem through a new design for "method handles", which he details in the blog Method Handles in a Nutshell.
Pulsar project
The Pulsar project is a Java-based peer-to-peer streaming client that allows the distribution of audio and video in the Internet, both live and on-demand. As viewers help forward the content, there is no need for strong servers. With the release of version 0.6 Pulsar has now become open-source and is hosted on java.net. Various subprojects, like the media player or its peer-to-peer protocols also work independently from Pulsar and can be reused for other projects.

Introducing Java 6 update 10
Ethan Nicholas has posted a new SDN article Introducing Java 6 update 10. He writes, "don't be fooled by its unassuming name: the upcoming Java 6 update 10 is a very different animal than the updates that preceded it. Java 6u10 pushes the envelope by adding more new features and functionality than in any previous Java programming language update release, including many that have been a long time coming." The article covers 6u10's major features, including the Java Kernel, the new Java Plug-In, the Java Deployment Toolkit, Nimbus look-and-feel, patching improvements, and more.
SigTest project
The SigTest project is based on Sun Microsystem's signature testing and API conformance tool of the same name. The SigTest tool makes it possible to easily compare the signatures of two different implementations of the same API. It verifies that all of the members are present, reports when new members are added, and checks the specified behavior of each API member. Originally developed to help in the creation of TCK test suites, it has since evolved into a general purpose tool that can be used to compare any two implementations of an API to determine their differences. The SigTest project is being created in order to develop a community that will improve it, further its development, and use it to develop test suites. We encourage you to browse, download, contribute, and get involved.

Does Cable "Get It"?
Over on OEDN, a site for developers using OpenCable/OCAP/Tru2way to develop interactive television applications, Will Kreth asks Does Cable "Get It"? "It's a question that needs to be asked. Because, beyond the dichotomy of "Professionally Created Content" vs. "User Generated Content" (sometimes referred to as "UGC") -- we're rapidly moving into the territory of "User CONFIGURED Content." Content that is arranged, assembled and edited as drag-and-drop, click-to-install elements that represent the entertainment/social dashboards of their lives. The "Widget Nation" is here, and combined with the move to time-shifted video viewing, a powerful dynamic is at play"

Adding Voice to Java EE With SIP Servlets
A recent EE Tech Tip, Adding Voice to Java EE With SIP Servlets, shows off how to use Session Initiation Protocol (SIP), a signaling protocol that is used to set up, modify, and terminate a session between two endpoints. SIP is used to set up a two-party call, a multi-party call, or even a multicast session for Internet calls, multimedia calls, and multimedia distribution. The Tech Tip covers some of the basic concepts underlying SIP and SIP servlets. It also presents a sample application that uses SIP servlets and HTTP servlets to provide VoIP phone service.
Marge 0.5 released

Will Closures Make Java Less Verbose?
Citing Steve Yegge's Execution in the Kingdom of Nouns, Bruce Eckel asks Will Closures Make Java Less Verbose? Summarizing and extending Steve's argument, Bruce writes "his point is that Java has gone so overboard into "everything is an object" that it prevents simple and clear expressions of ideas. His very clever translation of Ben Franklin's poem "For want of a nail" into Java makes the point better than anything. So here's my question: if closures allow you to be slightly more verby and slightly less nouny (in Yegge's frame of thought), will it allow programmers to create programs that are easier to read?"
JDIC Plus project
Cited recently by Kirill Grouchnikov and JavaLobby, the JDIC Plus project "is a Java Win32-extension development kit, enabling developers to use extended Microsoft Windows API functionality. Mainly the project implements the semi-lightweight wrapper component around Microsoft Internet Explorer (IE)." The project's four demos offer a web browser, Flash player, map explorer, and HTML editor.

JSF at Big Lots!
Ed Burns has posted a three-part video interview on TheServerSide, entitled JSF at Big Lots! Following a presentation at JBoss World 2008, Ed talked to Big Lots! developers Kunal Bajaj, Mark Hanes, Chris Henson and Keith Naas about their real-world use of JSF. "Big Lots! has had enormous success with Sun's JSF implementation, Mojarra, and other Java EE technologies in delivering inventory management and other store essential software on time and within budget.
My number one take-away from the presentation was a feeling of satisfaction in seeing a line-item validation of many of the design decisions within JSF. As you can see in the presentation, some of the JSF features leveraged by Big Lots! included, custom components, leveraging the JSF lifecycle, separation of rendering from components, custom converters and validators, [and] client device independence."
Fast Directory Deployment in GlassFish
Eduardo Pelegri-Llopart writes on The Aquarium about Fast Directory Deployment in GlassFish: "The Servlet specification describes how to deploy a Web Application as a
WAR file
but most AppServers,
GlassFish included,
support deployment from an (expanded) directory.
Directory deployment allows fast and easy detection of file changes and
thus can lead to an improved deployment experience.
Which is what Vance has been doing for
NetBeans 6.1 and
GlassFish v2.1 combination.
Check out the description of the new functionality, first through
Debug Tracing
and then via
Some Commentary."

SailFin: When Java EE Met SIP
SIP (Session Initiation Protocol) technology is behind many of today's popular services, such as VoIP, instant messaging, and web conferencing. Underpinning SIP is the SIP Servlet, initially defined in JSR-116 and, since then, updated in JSR-289. The latter defines a standard application programming model to mix SIP Servlets and Java EE components. The open source project SailFin adds a SIP Servlet technology extension to the GlassFish Application Server. In SailFin: When Java EE Met SIP, JavaLobby's Geertjan Wielenga interview the main developers involved in this project, Binod PG and Vince Kraemer.

Data Reaper project
So what's the new Data Reaper project about? Its owners explain, "we were working on the development project and to get data from one of our client's website with fine grained format to display on our application. The other team does not want to provide us the grained format to serve same information. We searched few websites (java.net, sourforge.net, etc) for similar project, parser, or code to re-use on our project and unfortunately, we did not find any parser or code. Therefore, we planned to start code under public license and others can use our code and update with new enhancements."
Spontaneousware project
The Spontaneousware project is an abstract framework platform targeted to develop middleware systems for mobile computing and mobile ad-hoc networks. Its architecture is designed to be a platform-independent and it can be implemented to any appropriate device and object-oriented language - for example, is possible to have an interoperable implementation for Java, Symbian or Windows Mobile. The project objective is to construct the first implementation of Spontaneousware aiming a middleware system for Java ME platform and Bluetooth network using JSR-82 API.
Closures: Control Abstraction, Method References, Puzzler Solution
Neal Gafter has posted an update to the BGGA closures proposal in the blog entry, Closures: Control Abstraction, Method References, Puzzler Solution. "The Java Closures prototype now supports control abstraction and
implements restricted closures and function types. The syntax has
changed slightly. Also, as hinted in the
draft JSR
proposal, there is now support for eta abstraction, which
is called method reference in
Stephen
Colebourne's FCM proposal. We haven't updated the
specification, so this will serve
as a brief tutorial on the changes until we do. I don't know if this
will be the syntax we will end up with, but it will do for now. Finally,
we look at solutions to the closure puzzler in my previous post."

Hudson Dashboard for GlassFish Builds
In a recent post to The Aquarium, Eduardo Pelegri-Llopart describes a Hudson Dashboard for GlassFish Builds. "The basic arrangement for the
GlassFish AppServer is:
sources are external (to Sun), we
use
Hudson on internal machines
to build and run all our tests,
then push out the builds out for everybody to use.
This arrangement works well for everybody except that
it is hard to track the build status from
outside of Sun, but that has now been fixed thanks to a new
Build Publisher
plugin contributed by a group at JBoss.
Check out the
build dashboard
and
Kohsuke's Announcement.
The plugin was discussed a few days ago in a
Separate Post,
and I clarified that it would qualify for the
GlassFish Awards Program;
I think it is a very useful plugin."
RESTful Access to JMX Instrumentation
Jean-Francois Denise has posted an OpenDMK add-on to provide RESTful Access to JMX Instrumentation. "Having simple HTTP-based access to a Java Management Extensions (JMXTM) MBean is an idea that I like a lot and one for which I think that there are thousands of real use cases. For example, when developping a Web application, integrating a piece of information obtained from JMX instrumentation, such as the status of a service, should be as simple as loading an HTML page." His blog contains details of how far this experiment has gotten, and how to run the prototype.
New Features in EJB 3.1, Part 2

Using voice commands to build software
1-800-HUDSON? In his Amazon blog entry, Jott to Build - use voice commands to build software, Paul M. Duvall describes an admittedly "gimmicky" technique to build his project via a voice command and a continuous integration server such as Hudson. "I dial an 800 number provided by Jott from my cell phone. When prompted, I say "Build Stage" and hang up. Jott sends my transcribed voice to my email account. On a scheduled basis, an Ant script parses my email searching for keywords. It finds "Build Stage", so it runs an Ant target to execute a remote deployment in the Stage environment."
NetBeans Wins Jolt Awards
For the second year in a row, the NetBeans IDE took home the "Best Development Environment" win at the 18th Annual Jolt Product Excellence Awards.

Sun to Bring Java to iPhone
"Sun Microsystems is developing a Java Virtual Machine for Apple's iPhone and plans to release the JVM some time after June, enabling Java applications to run on the popular mobile device," according an InfoWorld article. "The JVM is to be based on the Java Micro Edition (ME) version of Java, said Eric Klein, vice president of Java marketing at Sun, on Friday afternoon. Apple had not shown interest in enabling Java to run on the iPhone, but Sun plans to step in and do the job itself after having pondered Thursday's release of an SDK for the iPhone by Apple."

Brian Goetz on Java 7's ParallelArray class
Brian Goetz has posted the latest installment of a series on currency, Stick a Fork in it, Part 2, introducing an important new Java 7 class. "One of the additions to the java.util.concurrent packages coming in Java 7 is a library for fork-join-style parallel decomposition. In part one of this series, author Brian Goetz showed how fork-join provides a natural mechanism for decomposing many algorithms to effectively exploit hardware parallelism. In this article, he'll cover the ParallelArray classes, which simplify parallel sorting and searching operations on in-memory data structures."
An Update on Java ME JSRs
Coming off appearances at Mobile & Embedded Developer Days and other mobility-oriented conferences, JDJ's "JSR Watch" columnist Patrick Curran focuses on the state of ME and its relevant JSRs in JSR Watch: Java Mobile and Embedded Spotlight. "A total of 77 Java ME JSRs have made some progress through the JCP since its inception and 42 have been completed. Twenty Java ME JSRs were active in 2007 (getting started, publishing drafts, going to ballot, or making final or maintenance releases). A quick review of the active JSRs gives a clear picture of the breadth of technologies covered in the ME space: speech APIs (JSR 113), data synchronization (JSR 230), user interface customization (JSR 258), broadcast services (JSR 272), vector graphics (JSR 287), automotive telematics (JSR 298), event tracking (JSR 190), digital TV (JSR 242), and XML (JSR 280)."
