Hip Wrappers in the House

In March 2002, Sun Microsystems released Version 1.4 of its Java 2 Standard Edition (J2SE) software (http://java.sun.com/j2se/1.4). J2SE is the core of the Java platform. While other Java kits are specialized (e.g., J2ME is targeted at small devices and J2EE provides a range of server and e-commerce solutions), J2SE provides fundamental components that every Java programmer can use.

For example, the Java Container framework (Maps, ArrayLists, etc.), the input/output system, and Swing and AWT (two user interface toolkits for Java written and provided by Sun) are all a part of J2SE.

J2SE 1.4 is a substantial upgrade with more than thirty enhancements or additions — new APIs, development tools, and performance tweaks — that greatly extend Java’s capabilities. The additions to J2SE 1.4 fall into four categories: the integration of previously supplemental APIs into the core Java 2 platform; new APIs; new Java facilities (an addition to the Java language or a substantial set of new methods added to existing classes); and enhancements and bug fixes.

Here are some highlights from each area.

INTEGRATIONS AND NEW APIs

The Java API for XML (JAXP) and several Java security packages are now integrated in J2SE as part of the core platform.
Applications can use the new Java Logging API to generate event and activity logs. Logs can be emitted as plain text, XML, or can be sent to system log services such as syslog. Logs can also be captured in more than one place simultaneously.
