I have compiled my jar file using jar cmf manifest.mf SysInfo.jar *.class and got no errors, but when I try to execute the file by clicking on it nothing happens. I don't even get an error pop up. But when I run the jar using the console it will execute perfectly.

What can I do to make the file run by clicking it?

  • What kind of application is in the jar? Is it a command line app? Also, how are you running it from the command line (which command are you using)? – RudolphEst Jan 06 '17 at 13:36

    Please provide more information: How do you start it successfully from the console? How does the manifest file look like? – hotzst Jan 06 '17 at 13:39
  • What os? Essentially you have to tell your os what to do with jar files. – matt Jan 06 '17 at 13:52

Try starting it via console using 

java -jar yourFile.jar

Don't forget to cd in the directory your .jar file is located before you do this.

EDIT: Sorry, you already said it works like that. Try right click open with.. and then choose open with javaw.exe If that also doens't work you need to provide more information.

  • javaw only exists on Windows where it is already the default, and doesn't work if the program uses console I/O which I'm guessing is the problem, see links above. – dave_thompson_085 Jan 06 '17 at 20:37
