When double clicking a .jar file a cmd window opens briefly and then disappears, but the .jar file isn't executed

Question

I am looking for a solution to the problem posed in the title. When I double click a .jar file, or right click and open, it simply opens a black cmd window for a split second, then closes it, and nothing else happens. I know that the programs do not run, as a few that I have tried are installers, yet the program they are meant to install are nowhere to be found. Is there a way to fix this so that the files actually function?

Solution

.jars are not executable files. To execute a jar, open a terminal (by Start -> Run - > type cmd (ENTER) -> cd <path-where-jar-is>) and run:

java -jar <filename.jar>

No jar can execute (in Windows) by double clicking. If you want to achieve the "double clicking" effect, you will need to create a .bat or .cmd file (that is executable).

Normally the JAR extension is registered to be executed.

Keep in mind that jar extensions and files are userd to deliver malicious payloads...so, there is a slight possibility jar files are blocked by means of corporate secur policy, antivirus etc.
