Oracle (ORCL) announced JavaFX 2.0 and its plans to move Java forward and continue investment in mobile platforms such as Java ME and Oracle Application Development Framework (ADF) Mobile.

During the JavaOne 2011 strategy keynote, Oracle senior vice president Hasan Rizvi outlined plans for the future of the Java platform and showcased product demonstrations illustrating the latest Java technology innovations. Oracle said Java is run on 97 percent of enterprise desktops and that 80 percent of mobile developers target the Java platform.

Pronouncing that they would keep Java vibrant and moving forward through ongoing support for open standards, there were an array of partner-related announcements. Twitter, the OpenJDK Community, the Java Community Process (JCP), IBM, Intel and Red Hat, ARM, GetJar and Harris IT Systems also appeared on stage to demonstrate their ongoing support for Java technology.

Oracle announced the availability of  JavaFX 2.0 , an advanced Java user interface (UI) platform for enterprise business applications and the next step in the evolution of Java as a premier rich client platform. They also stated it was their intention to submit a proposal to open source the JavaFX platform as a new project within the OpenJDK Community. The new version introduces FXML, a scriptable XML-based markup language for defining user interfaces. JavaFX 2.0 allows the use of popular scripting languages that are supported on the Java Virtual Machine (JVM), including Groovy, JRuby and Scala. Oracle references a number of testimonials from customers using JavaFX.

This is the smallest and most cost efficient hardware module in Imsys’ SNAP family (Simple Network Application Platform). It builds on previous generations of the SNAP FX (small mezzanine) and SNAP Classic (SIMM72) modules. Featuring the newest Imsys processor generation and providing full access to the processor’s features, it’s ideal for OEMs needing a powerful computer on module for minimizing time-to-revenue.

The SNAP Stamp is based on the Imsys native mode IM3910 Java processor. This allows user Java applications to run natively on the processor without the slowness of Java byte code interpretation or requiring costly special compilers – just copy your Java class or jar files over and run them. Firmware and application software can be uploaded and managed through the network connection, including remote software upgrades. It contains a full TCP/IP stack, CLDC environment, Web / FTP / Telnet servers, device drivers for various I/O interfaces and an easy to use command line interface. Included standard is the Rubus™ real-time operating system that is well proven in safety critical applications and the fail safe flash file system with wear leveling and power fail recovery. The embedded real-time Java environment greatly accelerates development and eases deployment.

Java class files generated by any Java IDE (Eclipse, Netbeans) are directly executable on the SNAP Stamp. Development kit hardware and reference designs are available. The Imsys Developer (a complete Windows-based IDE) can be utilized for hardware debugging and software development in Java, C and assembler, with breakpoints, dynamic variable inspection, and single step debugging at all levels.

Imsys may make changes to specifications and product descriptions at any time, without notice. Java and all Java-based marks are trademarks or registered trademarks of Oracle Corporation.

Last Tuesday, Board President and Green Executive Officer Steve Ma of Live Green spoke to students at the Robert H. Smith School of Business about his experiences starting and running a triple bottom line business.

Last Tuesday, Board President and Green Executive Officer Steve Ma of Live Green spoke to students at the Robert H. Smith School of Business about his experiences starting and running a triple bottom line business. "I have power, real power to change people, ideas and things," said Ma as he spoke of what he referred to as his aim to have a positive ripple effect on the world.

Ma, who frequently visited Java Green, a business that employs sustainable and socially responsible practices, began to wonder why there weren't more businesses like this coffee shop. From that idea, Live Green was born.

Live Green was created as a triple bottom business that focuses on helping consumers and business owners employ sustainable practices, help the planet by creating more green businesses, and lastly to profit.

When we first heard rumors of Dart , the new client-side Web programming language from Google, it was described as a "JavaScript killer," aimed at replacing a language seen as "fundamentally flawed." Those early reports spurred various reactions from the Web development community, ranging from unabashed excitement to bemused skepticism to worry that Google was trying to usurp the open JavaScript standard in true Microsoft fashion.

Google officially unveiled Dart this week, during a keynote address at the annual GoTo conference in Aarhus, Denmark. Thankfully, it seems to live up to much (though not all) of the hype, while falling far short of the worst fears. In fact, based on the documentation and tools released so far, Dart may be exactly what many client-side Web developers have been waiting for.

Maybe. It's important to realize that Go and Dart are parallel efforts, each with different goals. Go is a classic compiled language that outputs binaries as processor-native machine code. In that sense, it's closer to C and C++ than to Java or dynamic languages such as JavaScript. Go is intended as a general-purpose and systems programming language with some modern features, such as garbage collection and baked-in support for parallelism.

Dart, on the other hand, is a VM-based language that seems to have much more in common with JavaScript than the initial reports would have us believe. One revelation from this week's announcement was that Dart is intended to run not only in the browser but also on servers via a stand-alone VM, much like how Node.js enables JavaScript on servers . Still, most Dart code will probably be client-side, and for the time being, the way to run it is to compile it into JavaScript code that can be executed by modern Web browsers (including Chrome, Firefox, and Safari for now, with more to come).

AppDynamics, Inc., the leader in application performance management (APM) for the cloud generation, today announced version 2.0 of its free java troubleshooting solution , AppDynamics Lite. The new version dramatically expands the solution's capabilities by adding visibility into JMX metrics as well as offering proactive alerting, enabling application Development and Operations teams to be notified when application performance degrades in production.

The free Java troubleshooting product, which recently surpassed over 50,000 downloads, supports IT Ops and Dev teams who need to rapidly troubleshoot and diagnose application performance problems in production. The solution installs in minutes, identifies and monitors an application's business transactions, and gives immediate insight into common application issues such as slow SQL, stalls, errors, and slow response time.  With the additional ability to monitor JMX metrics, as well as set up alerts that trigger based on an application's performance, AppDynamics Lite 2.0 becomes the most powerful free production monitoring tool in the industry.

While Dev and Ops teams typically use profilers to gather data and resolve problems, such tools are ill-suited for production environments where they will create heavy overhead and degrade the application's overall performance. AppDynamics Lite runs with less than 2% overhead in most production environments, yet gives complete visibility into a single Java Virtual Machine (JVM), as well as code-level details when performance problems arise. This makes the solution suitable for tomcat monitoring , jboss monitoring , weblogic monitoring , websphere monitoring , and any other application sever that runs on Java 1.5 and above.
