At this weeks DevCon 2010, the annual conference for BlackBerry developers, Research in Motion has announced new tools for Java developers.
The BlackBerry Java Plug-in for Eclipse running on MacOS X was announced with a Technical Preview being available to download.
"The BlackBerry Java Plug-in for Eclipse Tech Preview for Mac OS X is based on the BlackBerry Java Plug-in for Eclipse v1.1.2 and supports Mac OS X 10.6 (Snow Leopard). This initial beta focuses on Java® development for BlackBerry® 6 with tethered device debugging on the BlackBerry® Torch™ 9800 smartphone."
In addition to releasing tools for MacOS X developers, RIM has announced several new platforms that will be available to BlackBerry Java developers over the coming months:
  • Advertising Service
  • Payment Service
  • Analytics Service
The advertising service (which is currently already available) allows developers to add advertisments into their applications with as little as 3 lines of code.  The payments service allows developers to add the facility to take payments for products or services securely, directly from the mobile device.  The analytics service allows developers to gain information such as how many times their application is loaded, or how much time a user spends running the application etc.
Full details of these 3 new services can be found in the BlackBerry Developer's Blog.
