9 steps to open JAR file
The following recommendations and steps will help you open the Java Archive Format file in case you cannot do it in the standard way:
- The user must verify that the operating system used by him is compatible with the file Java Archive Format. Files with the JAR extension may not be supported by the operating system you are using.
- No default WinZip Mac Edition application in the system or Web browser, WinZip, Eclipse, Java Runtime Environment will prevent you from opening JAR files. If there is no such program, install it (or download it earlier).
- Make sure that one of the WinZip Mac Edition, Web browser, WinZip, Eclipse, Java Runtime Environment programs is the default application for opening JAR files in the system. If not, open the dialog box with the properties of the Java Archive Format file and use the "Change" button on the "General" tab. The system will display a window with applications to choose from, from which you should select one of the WinZip Mac Edition, Web browser, WinZip, Eclipse, Java Runtime Environment programs.

Try to download or copy the file again.

- Check that the Java Archive Format file format is not outdated. In this case, you may find that the newer version of the application does not support this older format.
- An attempt to open the Java Archive Format file by an un-updated application may fail. Check the app for up-to-date information and, if necessary, install the latest version.
