Platforms

JACK is implemented entirely in Java and runs on Java versions 1.1.3 and later. The graphical components require Java 2 v1.3 or later. JACK has been tested on the following platforms:

	Windows 95/98/Me
	Windows XP/2000/NT 4.5
	Solaris 2.5, Solaris 2.6, Solaris 7 (also called 2.7)
	Linux i386 (libc5 and libc6)
	Mac OS X 10.1 +

JACK agents can be developed and deployed on any platform for which a suitable Java implementation is available.

Development-system

JACK development has the following requirements:

	A Java Compiler and Runtime environment must be available ( JDK v1.1.3 or later).
	JACK requires Java 2 Version 1.2 or later to run the graphical editors.
	The installed JACK package requires 2Mb of disk space.

Sun specify that their Java 2 Software Development Kit has the following requirements:

	Win32 Version for Windows 95, Windows 98 and Windows NT 4.0 on Intel hardware. A 486/DX or faster processor. 32 megabytes RAM minimum, 48 megabytes RAM recommended.
	Solaris/SPARC Version. Only Solaris Versions 2.5.1, 2.6, 7 and 8(also known as 2.7 and 2.8) are supported. 32 megabytes RAM minimum, 48 megabytes RAM recommended.
	Solaris/Intel Version. Only Solaris Versions 2.5.1, 2.6, 7 and 8 (also known as 2.7 and 2.8) are supported. A 486/DX or faster processor. 32 megabytes RAM minimum, 48 megabytes RAM recommended.
	On all systems you should have 65 megabytes of free disk space before attempting to install the Java 2 SDK software. If you also install the separate documentation download bundle, you need an additional 90 megabytes of free disk space.

To carry out development in JACK, we suggest that Sun's larger "recommended" memory sizes will be needed.

Execution-system

Executing an application developed using JACK requires:

	the JACK Runtime Environment
	a Java Runtime Environment
	a UDP/IP networking stack

The system requirements for these components are relatively small. To give an indication of the resource requirements, the JACK Runtime Environment should run under PersonalJava, which is Sun's specification of a simplified Java for running on low powered machines such as Personal Digital Assistants (PDAs).
