operating system with aJava virtual machine as a fundamental component. It is developed bySun Microsystems . Unlike Windows, Mac OS,Unix orUnix-like systems which are primarily written in theC programming language , JavaOS is primarily written in Java.As of 2006, Sun considers JavaOS a
legacy system .Design
The system is based on a hardware architecture native
microkernel . The Java virtual machine runs on top of the microkernel.Platforms that the kernel runs on include:
* ARM
*PowerPC
*SPARC
*StrongARM
*x86 All
device driver s are written in Java and executed by the virtual machine.A graphics and windowing system, implementing the AWT API is also written in Java.
Applications
JavaOS was designed to run on
embedded system s and has applications in devices such as set top boxes, networking infrastructure and ATMs. It's also the operating system that comes with theJavaStation .Future
Sun now officially considers JavaOS a
legacy system and recommends migrationtoJava ME . [ cite web | title = entry on JavaOS | work = CDC FAQ | url=http://java.sun.com/products/cdc/faq.html#cp8 | accessyear = 2006 | accessmonthday = October 11 ] This by itself however is not a full replacement, as Java ME is anAPI specification, which runs on top of an operating system, and is not an operating system in itself.See also
