Deep Dive: Java Warehouse and Java Store With Bernard Traversat

The Java Store is a JavaFX-powered storefront that provides an easy and secure way to discover and acquire compelling Java and JavaFX applications. Social networking, games, productivity tools, and business applications are examples of what you can download from the Java Store.

The Java Warehouse is the repository for applications submitted for distribution through the Java Store. As an application developer registered to the Java Warehouse, you can submit your desktop applications to the Java Warehouse and make them available through the Java Store to a huge potential base of consumers. Soon you'll be able to monetize those applications.

Learn more about the Java Warehouse and Java Store in this Deep Dive with Bernard Traversat, the Director of Engineering for the Java Store. Note that due to the timing of the video taping of the Deep Dive, the Java Store applications shown are only placeholders for the real applications.

Deep Dive: Sun GlassFish Web Space Server, An Interview With James Falkner

At the 2008 JavaOne Conference, Sun made an exciting announcement regarding a collaboration agreement it reached with the Liferay open portal community. Both companies agreed to share code and release products from a common codebase. Sun GlassFish Web Space Server is an outgrowth of that common codebase, bringing together features and technologies from Liferay as well as Sun's OpenPortal communities.

In this Deep Dive, James Falkner, Sun's Product Architect for portal technologies, demonstrates many of the features that Sun GlassFish Web Space Server offers for administrators, developers, and end users. Along the way, he demonstrates some cool features such as hooking portlet events together graphically, and changing the theme for a portal page in Adobe Dreamweaver using Web Space Server's View Designer plugin.

Here's a screen shot of hooking portlet events together:

Campus Cast 7 Riddle

The technical lead for my project comes up to me and says, "Jordan, could you please write me a method that prints out all of the perfect squares between 1 and 1000?" A perfect square, of course, is a number which is the product of the same number. For example, 4 is a perfect square because it is 2 times 2. 9 is the next perfect square because it is 3 times 3. I say, "Piece of cake, I'll just write a loop between 1 and 1000 and during each iteration multiplies the number by itself to get the perfect square." So I hand the code my my technical lead, and he looks at my with a scowl. "Humph" he says, "I think multiplying the two numbers will take too long. I bet you can do this with at most a few additions during each iteration of the loop."

What solution does my project lead have in mind?

Answer:

We can easily write a program that computes and prints the perfect squares that looks something like this:

    for (int x = 1; x <= 1000; x++) {
        int square = x * x;
        System.out.println("The next perfect square is " + square);
    }

However, that does a multiplication each iteration of the loop. We realize that if we know the perfect square for 'x', then the perfect square for (x + 1) is (x + 1) * (x + 1). When we expand this, we get x^2 + 2x + 1. So if we already know x^2 from the previous iteration of the loop, we can compute the perfect squares much quicker as follows:

    int square = 1;
    System.out.println("The next perfect square is 1");
    for (int x = 1; x < 1000; x++) {
        square = square + x + x + 1;
        System.out.println("The next perfect square is " + square);
    }

Deep Dive: JavaFX

JavaFX is a platform for creating and delivering Rich Internet Applications (RIAs) -- web applications that use rich media types such as video, audio, graphics, and rich text -- that can run in a wide variety of devices, anywhere from handsets-to-laptops-to desktops. In many cases, you can compile and run the same JavaFX application code in a mobile environment, a desktop environment, or in a browser.

The JavaFX platform combines a declarative scripting language, JavaFX Script, and set of tools that make it easy build RIAs quickly and collaboratively.

Here's a screen shot of the kind of cool RIAs you can easily build with JavaFX:

It's a 3D display shelf. If you click an image in the real Display Shelf application, the display moves the selected image to the front, rotating the other images forward or backward. You can see the application in action here.

JavaFX is really an exciting platform with a lot of potential in the RIA development arena. With this in mind, I invited Jacob Lehrbaum, the Senior Product Line Manager for JavaFX Marketing at Sun Microsystems, to demonstrate some of the exciting features in the platform. Watch it. I think you'll lenjoy it.

The GlassFish team has put together a selection of webcasts, screencast and podcasts outlining various aspects of the product. Enjoy!

Deep Dive: Sun Studio

Sun Studio is a toolset for C, C++, and Fortran developers. It's a comprehensive toolset that includes compilers, libraries, code and memory debuggers, performance analyzers, as well as other application development and productivity tools. In addition, Sun Studio offers an integrated development environment based on the NetBeans IDE. Significantly, Sun Studio includes leading-edge support for developing parallelized applications targeted at multicore systems. In fact, the latest Sun Studio release, Sun Studio Express 11/08, includes full OpenMP 3.0 compiler support and enhanced support for Open MPI in the performance analyzer. OpenMP is an API designed to enable developers to build applications that take advantage of multicore systems. Open MPI is an open source Message Passing Interface (MPI) implementation that enables developers to build applications that take advantage of clusters of systems -- something particularly important in the High Performance Computing (HPC) space.

With all this functional richness, Sun Studio presents a very attractive development platform for application developers. With this in mind, I asked Ikroop Dhillon, the Product Marketing Manager for Sun Studio, to show us the toolset in action.

Watch this video and see Ikroop demonstrate some of the features and tools in Sun Studio Express 11/08 such as the Sun Studio IDE, the new dbx debugger, and the performance analyzer. Here's a screenshot of the dbx tool being used to debug a Tetris game:

In this eipsode, we sit down with Matt Zandstra, author of PHP Objects, Patterns, and Practice, Second Edition, and talk about why he wrote this book, why patterns are not a fad, and other topics related to PHP.

A few weeks back, I had the pleasure of meeting Lorna Mitchell, at ZendCon in Santa Clara, California. We first met at the Sun booth (yes, Sun has products to support PHP). We struck up a brief conversation as I tried to get her to join the Sun Developer Network. I learned she belonged to PHPWomen.org which is a very influential group in the PHP community. I was taken aback by this since women developers are not the majority. To have a group of them be a key piece of a developer community seemed too good to be true! I stayed in touch with Lorna, so that I could learn more about this group and share with the SDN Channel listeners. In this podcast, you'll learn more about Lorna herself and the PHPWomen.org. Please enjoy and stay tuned as I will try to have more members of this group in to talk with me.

If you have a development group/community you'd like to talk about on SDN Channel please e-mail us.

Deep Dive: Lightweight User Interface Toolkit (LWUIT)

Last May I had the opportunity to attend a technical keynote session on mobility tools and technologies at the 2008 JavaOne Conference. There were a number of interesting demos, but the one that really caught my eye was a demonstration of the Lightweight User Interface Toolkit (LWUIT) by Yoav Barel, the manager of the Sun group in Israel that developed the toolkit. LWUIT is a lightweight user interface (UI) library that developers can bundle with their applications. Significantly, LWUIT allows developers to overcome a lot of the challenges they face in creating compelling UIs for mobile devices and in making those UIs appear and act consistently across the range of mobile devices that run Java Platform, Micro Edition (Java ME). Think Swing for mobile devices and you'll come pretty close to the power and functionality of LWUIT. In fact, the development team was inspired by the Swing approach, even to the point of adopting Swing's MVC paradigm.

LWUIT Demo Screen

LWUIT offers a wide range of features for UI development including support for rendering, tabs, layouts, transition effects (even 3D rotation), as well as an easy to use theme editor targeted to graphic designers. But the really amazing thing is that the team was able to fit all this functionality in a footprint that's rightsized for small mobile devices.

I came out of that session inspired by the demonstration and when it came time to schedule a deep dive on a mobility-related topic, I lost no time in contacting Yoav Barel. As it happened, Yoav was scheduled to participate in some meetings in the San Francisco Bay area. This gave me and other members of the SDN team the opportunity to do a deep dive with him on LWUIT. We hope you enjoy it. We sure did.

Had to share the latest Episode of This Ain't Your Dad's Java. It may not be video, but well worth the listen. Eric and Jenn (with David there in spirit) sit down with the man who started it all, James Gosling to talk all about Java. From the beginning when Java was just a thought, to where Java is today, Java ME/SE, to JavaFX, we discuss what Java means to James and to the world. As always, we dive into some of our favorite toys, what boxes we got from Amazon.COM, what we are reading and what music has us rocking out.
