The two principal products in the Java SE platform are: Java Development Kit (JDK) and Java SE Runtime Environment (JRE).

The JDK is a superset of the JRE, and contains everything that is in the JRE, plus tools such as the compilers and debuggers necessary for developing applets and applications. The Java Runtime Environment (JRE) provides the libraries, the Java Virtual Machine, and other components to run applets and applications written in the Java programming language.

The following conceptual diagram illustrates all the component technologies in Java SE platform and how they fit together.

What's New in Java SE Documentation

Java SE documentation is regularly updated to provide developers with in-depth information about new features in the Java platform. Some recent updates include:

Customizing the RIA Loading Experience Customize the rich Internet application loading experience by providing a splash screen or a customized loading progress indicator to engage the end user when the RIA is loading and to communicate measurable progress information.

See the following topics for more information:

Customizing the RIA Loading Experience topic for conceptual information
Customizing the Loading Experience topic in the Java Tutorials for step-by-step instructions and examples

Mixing Signed and Unsigned Code Signed Java Web Start applications and applets that contain signed and unsigned components could potentially be unsafe unless the mixed code was intended by the application vendor. As of the 6 update 19 release, when mixed code is detected in a program, a warning dialog is raised.Mixing Signed and Unsigned Code explains this warning dialog and options that the user, system administrator, developer, and deployer have to manage it.

SeeOracle Java SE and Java for Business Critical Patch Update Advisory - March 2010 for details.

Java Rich Internet Applications Development and Deployment Rich Internet Applications can be developed and deployed as applets or Java Web Start applications. Thenext generation Java Plug-in introduced in Java SE 6 update 10 provides powerful capabilities to applets.
