No JAR Files Opening Correctly

Question

I'm trying to open a JAR file, but it won't open. I've tried:

Reinstalling Java.
After renaming the file to example.jar, I tried java -jar (I got an Error: Unable to access jarfile example.jar).
Double clicking on the file/. I think that it's using JavaTM Platform SE Binary because it shows a little coffee thing as the thumbnail.
Right clicking and selecting "open with," then selecting JavaTM Platform SE Binary.

What else can I do? I've tried different JAR files as well, and it doesn't work. I guess that there's something wrong with how my system opens the JAR files, but I'm not sure what to do.

Thanks for the help!

Have you set the CLASSPATH? It seems that java can't find the jar file you specified — Papershine, Jan 31 '17 at 02:50
did you try java -jar example.jar. Error "Unable to access jarfile" is shown when java could not find the jar file in the current directory — ravthiru, Jan 31 '17 at 02:51
Have you tried unzip it? Any zip tool will work. The jar format is the same — bichito, Jan 31 '17 at 02:52
Possibly this problem? [http://stackoverflow.com/questions/11943948/error-unable-to-access-jar-file](http://stackoverflow.com/questions/11943948/error-unable-to-access-jar-file) — Papershine, Jan 31 '17 at 02:53
Oh and does your jar have GUI? If not, nothing will happen if you double click it — Papershine, Jan 31 '17 at 03:01
@efekctive I'll try that, but the jar file installs something, so I'd prefer to just run it. — TheKingElessar, Jan 31 '17 at 03:01
a copy of the file in another dir. this way you will know if it is corrupted — bichito, Jan 31 '17 at 03:04
Oh and you need to use the `cd` command to change to the directory that contains the jar. Else java can't find the jarfile of course — Papershine, Jan 31 '17 at 03:08
Thanks everyone for your suggestions; I read over this (per suggestion from @HilaryLau): http://stackoverflow.com/questions/11943948/error-unable-to-‌access-jar-file. I used the complete path to the file in CMD and it worked! I'd like to not have to do that every time, so I'll look into everyone's suggestions more. Thanks! — TheKingElessar, Jan 31 '17 at 03:08

You must either specify the full path or change to the directory that contains it, as I specified earlier. I don't think there is any way around this – Papershine Jan 31 '17 at 03:10

@HilaryLau No 'workaround' required. (a) It is working as documented; (b) it is working exactly the same way as any other command where you specify a filename argument. You have to supply a correct path. – user207421 Jan 31 '17 at 03:18
