Files on a file system that can be viewed (read) by any user. For example: files residing on Web servers can only be viewed by Internet users if their permissions have been set to world readable.

A scope over which security policies are defined and enforced by a security administrator. A security policy domain has the following characteristics:

It has a collection of users (or principals).

It uses a well defined authentication protocol(s) for authenticating users (or principals).

It may have groups to simplify setting of security policies.

A set of properties associated with a principal. Security attributes can be associated with a principal by an authentication protocol.

An item of data named by an identifier. Each variable has a type, such as int or Object, and a scope. See also class variable, instance variable, local variable.

Uniform Resource Locator. A standard for writing a text reference to an arbitrary piece of data in the WWW. A URL looks like "protocol://host/localinfo" where protocol specifies a protocol to use to fetch the object (like HTTP or FTP), host specifies the Internet name of the host on which to find it, and localinfo is a string (often a file name) passed to the protocol handler on the remote host.

A 16-bit character set defined by ISO 10646. See also ASCII. All source code in the Java programming environment is written in Unicode.

A system that runs a very light operating system with no local system administration and executes applications delivered over the network.

An abstract specification for a computing device that can be implemented in different ways, in software or hardware. You compile to the instruction set of a virtual machine much like you'd compile to the instruction set of a microprocessor. The Java virtual machine consists of a bytecode instruction set, a set of registers, a stack, a garbage-collected heap, and an area for storing methods.

A collection of graphical user interface (GUI) components that runs uniformly on any native platform which supports the Java virtual machine*. Because they are written entirely in the Java programming language, these components may provide functionality above and beyond that provided by native-platform equivalents. (Contrast with AWT.)

A Java keyword used in variable declarations that specifies that the variable is modified asynchronously by concurrently running threads.

Provides the services and management functions required to support transaction demarcation, transactional resource management, synchronization, and transaction context propagation.

A Java keyword that allows the user to throw an exception or any class that implements the "throwable" interface.

A Java keyword that can be used to represent an instance of the class in which it appears. this can be used to access class variables and methods.

A class or interface.

Transmission Control Protocol based on IP. This is an Internet protocol that provides for the reliable delivery of streams of data from one host to another. See also IP.

A Java keyword used to declare a loop that iterates a block of statements. The loop's exit condition is specified as part of the while statement.

A keyword in the Java programming language that indicates that a field is not part of the serialized form of an object. When an object is serialized, the values of its transient fields are not included in the serial representation, while the values of its non-transient fields are included.

An object that encapsulates and delegates to another object to alter its interface or behavior in some way.

A test suite, a set of tools, and other requirements used to certify an implementation of a particular Sun technology conformant both to the applicable specifications and to Sun or Sun-designated reference implementations.

A Java keyword used in method declarations to specify that the method does not return any value. void can also be used as a nonfunctional statement.
