Instructions
Step 1
The developers of the java language have created a special utility called JavaTM Archive for working with jar files in a conventional operating system. It is part of the Java Development Kit. Download the program on the developer's website. Install the program by double clicking on the installation file. You can find it on a special website at the lin
Step 2
Start the java interpreter and enter the command java -jar jar-file, where instead of file, specify the name of the file you want to open. This command works in JRE version 1.2 or higher. For more detailed instructions, see the java language help. It is also worth noting that for this software to work correctly, antivirus software must be disabled on some computers.
Step 3
You can try to run the jar as a browser gadget - a so called applet. To do this, you need to create an html page, inside which, using the applet tag, specify the name to the jar file. Do not download this program from other sites, as recently under this guise various viruses are hiding, which completely copy important information from the computer, steal passwords, destroy the entire operating system.
Step 4
You can open the jar format like a regular archive using the Winrar application. Select the file and click the Unzip button. The unzipped files are available for editing, for example, in the usual "Notepad". This software is installed by default with the operating system on the computer.
Step 5
You can convert a jar to a file with a more familiar exe extension using the JAR2EXE Converter utility. The program is very easy to use: you just need to specify the path to the jar file and the location to store the converted file. The choice is entirely up to you. You can use both options for a perfect jar experience.
