What is Java 2 Platform, Standard Edition (J2SE platform)?
The J2SE platform is the set of Java technologies that delivers to developers the primary value proposition of Java technology- “Write Once, Run Anywhere”. It provides a layer of abstraction between the developer and the native (OS) platform libraries and utilities so that Java code can be developed to a single specification but deployed to a variety of operating system environments. The J2SE platform comprises the Java 2 runtime environment, development tools and APIs. The Java 2 SDK (Software Development Kit) includes both the Java 2 runtime environment and the Development Tools and APIs. For Solaris Operating System (OS) customers, Sun’s recommended starting point is the web site for Java technologies for the Solaris platform: http://www.sun.com/solaris/java.
