Open jar in windows 8

Keep in mind that this only works if the jar file to be opened is executable. If it's not executable, you can view files within it instead. If double-clicking the jar file does not result in the file being run, it's likely not an executable file and cannot run in this manner. Read the next section on how to view the contents of the jar file. If the jar file opens using an archive program, such as WinRAR or 7-Zip, and you want Java to open it instead, follow the instructions below.

Have you tried going to the command line and running the jar file to see if any errors are being thrown? What command do have executed?

A better approach would be to package all the files into a single file that Java could access to run an application. Inspired by WinZip, JAR is a file archive used by Java to hold anything from multimedia files to code and is accessible to Java applets. Not only does this give you the ability to open. You still need to have Java installed on your computer to open JAR files from the command prompt, so that step comes first.

JAR files are archived data with a fancy name. JAR files are usually Java applications packaged into a single file. As JRE is free to download, this is the easiest way to get. On the other hand, if you just want to look at the contents of the JAR archive but not actually run it, you can always use a file extraction tool.
