Standard and Enterprise

Minimum Edition to create Java programs

SE plus components that are for developing enterprise programs.

Enterprise programs entails multiuser, multitier applications.

This is what is needed to run Java programs

Tools in different categories aiding development of Java programs.

Most have a command line interface.

These are the tools needed to compile, run and debug Java programs.

These tools are to setup and use RMI (Remote Method Invocation).

RMI is Remote Procedure Calls - calling methods in another object that is located remotely from the computer the calling object is located on; distributed computing.

These tools are for internationalization tasks.

These tools deal with keys and certificates to ensure safe computing.

A whole course could be devoted to Java security.

These tools deal with naming resources in a distributed computing environment.

These tools deal with the plug-in for browsers that cause it to use the new Java Virtual Machine in Java 2 v1.3. Otherwise, the JVM that is packaged with the browser is used and maybe an older version and not have the new features of Java 2.

Object, methods and behaviors that MUST be implemented to have a true Java Platform.

The Java Platform can be written by other vendors besides Sun. Sun maintains control of the Java Platform specification at this point.

A collection of useful object and methods to be used in Java programs.

More advanced objects – JavaBeans, JDBC, JFC, etc…

Enterprise objects – JSP, Servlets, Transactions, etc…

Objects that provide specialized functionality. Classified as optional extensions so that the Core Java environment doesn’t have to be burdened down with unnecessary bulk.

Extensions that are considered part of the Standard Edition of Java.

A vendor must implement an extension as specified by Sun.

Extensions that are considered part of the Enterprise Edition of Java.

A vendor must implement an extension as specified by Sun.

Other technologies and API’s for Java. There is no official Sun specification that other vendors must conform to with these components.
