Download Jigsaw

Jigsaw should run on any platform supporting Java, version 5.0 or later.

  1. Jigsaw requires Sun's JDK (Java Development Kit), version 5.0 or later. If you do not already have it on your computer, Java is available from java.sun.com.

  2. Download Jigsaw's JAR file from Jigsaw's SourceForge.net page.

  3. To execute the program:

    • With the generic .jar file: On Windows and MacOS systems, you will likely be able to start Jigsaw by simply double-clicking the JAR file. If that doesn't work, or you use a Unix-based systems, you can type ``java -jar jigsaw-XX.jar'' at the command line.

    • With the MacOS X version: Once the downloaded .tar.gz version is uncompressed (this will likely happen automatically), just double-click the Jigsaw icon to start.

    • With the Windows version: Simply double-click the downloaded .exe file.

  4. Jigsaw will likely work immediately. However, if it has problems with compiling and executing programs, you may need to enter its Preferences window, select the Java tab, and configure Compiler Location so that it references the javac.exe file from the JDK you installed in Step 1 above. Similarly, you may need to configure JVM Location to reference either javaw.exe (preferred) or java.exe.
