ojwc-use-cases-small.jpgWith over 3 billion devices and counting, Java on mobile devices is enjoying growth and huge adoption in many key markets around the world.

In the meantime, developers are pushing to build richer and more interesting applications, both from a functional as well as a user interface perspective. New use cases in mCommerce, social networking, location-based services, mobile cloud features, and access to functionality on the operator network are catalysts to create and deliver new compelling applications to the largest mobile user base.

To that end, Oracle is revving the mobile Java platform with Oracle Java Wireless Client 3.1 (OJWC). OJWC is an industry-leading Java ME implementation geared towards device manufacturers, operators, and OEMs who want to get to market quickly with a full-featured, high-performance mobile Java runtime.

This latest 3.1 release provides the following new functionality:

  • SIM Extensions—Enable remote content management on mobile handsets through SIM-based services
  • Oracle Mobile Developer APIs—Allow new use cases for Java ME applications on feature phones
  • Improved Content Management APIs—Facilitate content discovery and deployment
  • Network APIs—Leverage data from operator’s network for running smarter Java ME applications on resource-constrained devices
  • Other Enhancements—Aid integration with the device platforms

Oracle Java Wireless Client 3.1 will become available on devices over time as it is rolled out in markets around the world.

For developers, the new features such as the Oracle Mobile Developer APIs and the Network APIs are of particular interest. You will be able to start building applications for OJWC 3.1 with the upcoming next release of the Java ME SDK – stay tuned for this.

jt-harness.png JTHarness is one of those projects that may not be very well known to the general developer population, but which are nevertheless critical to many software projects.

JTHarness is a general-purpose, fully-features, flexible, and configurable test harness well suited for many types of unit testing. The JTHarness team has been continually maintaining and improving the code for several years now and the 4.4.1 Milestone Release 1 (MR1) went live on December 21.

Release 4.4.1 is a maintenance release which fixes bugs and includes the following notable changes:

  • Makes the “Report Converter” tool easier to use
  • Improves the speed of loading the ResultCache file
  • Shortens harness start-up time
  • Allows known test execution ordering
  • Adds new “Save view filter” settings
  • Improves COF functionality

JTHarness 4.4.1 is compatible with JTHarness 4.4. See the release notes for further details.

nb-rs232.png As reported four weeks ago, Ingmar Hendriks has been working on improving integration of microcontroller development with the NetBeans IDE.

Ingmar just released the new RS232 communication plugin for NetBeans, called nbplugin-avr. This plugin features sending, receiving, displaying, and logging of serial data from within the NetBeans IDE as well as setting configuration parameters and some handy UI features. The plugin also offers a public API which allows other NetBeans modules to leverage RS232 communications.

Next, Ingmar will be working on adding support for AVR/Ardunio microcontrollers in the NetBeans IDE. Great stuff – this brings a new class of development targets and better integration to NetBeans!
