.jar file refusing to open, just get "A Java Exception Has Occurred"

[u/fishebake]

It previously worked just fine, computer updated on its own and it stopped working. It's a Shimeji, a little guy who wanders over my screen while I do things on the computer. I tried the cmd thing? "cd downloads" and got the following in response:

"C:\Users\"computer name">cd downloads

C:\Users\"computer name"\Downloads>java -jar Shimeji-ee.jar

Error: Unable to access jarfile Shimeji-ee.jar"

I downloaded the latest version of Java and nothing happened. I don't really know computers so I'm at a loss here. Any assistance would be greatly appreciated.

We need a lot more context to be able to help. For starters, copy and paste the entire output including the stack trace. It would also be very helpful if you had the source code of that jar file.

C:\Users\"username"\Downloads>java -jar Shimeji-ee.jar

Error: Unable to access jarfile Shimeji-ee.jar``

this is all there is, all I changed was my username because it includes my real name. I don't think there's a stack trace included here? Also, how do I find the source code of the jar file? Thanks!!

That sounds more like the jar file just does not exist in the Downloads folder

I get the same error when i put random characters for the jar file:

C:\Users\mail>java -jar dasds.jar

Error: Unable to access jarfile dasds.jar

Unable to access jarfile

Find out why java can't access that file.

How do I do that? I’m sorry, I don’t know computer things that well.

[u/_Super_Straight]

Run the jar file from cmd, paste the full stack trace in pastebin, then post its link here.

[u/fishebake → u/_Super_Straight]

https://pastebin.com/3RwWVfhD this is what I got when I attempted to run the jar file. I'm not familiar with anything coding related so I apologize if I ran it wrong.

[u/_Super_Straight → u/fishebake]

No run it like this:

java -jar Shimeji-ee.jar

[u/fishebake → u/_Super_Straight]

ah! sorry, thank you for the correction! https://pastebin.com/XsuGcW4Q here's what happened when I did that.

[u/jonathancast → u/fishebake]

The - goes before jar not before Shimeji-ee.jar. Like this:

java -jar Shimeji-ee.jar

If that doesn't work, can you confirm that the jar is still there? Try running the dir command and see if that file is listed.

If I had to guess, Windows deleted your jar to conserve disk space, maybe because of a setting like this. I would strongly recommend checking your Storage Sense settings and disabling any settings that mention deleting files out of Downloads, and I would also strongly recommend copying any files you need to keep long term out of Downloads and putting them somewhere else, like Desktop or Documents. Downloads is meant to be a temporary directory, not a long-term storage location. (Although disk space is not so precious you can't clean it up manually, seriously, wth Microsoft?!).

[u/fishebake → u/jonathancast]

you know what, I think you're right. the original zip file is there, but the jar looks to be gone. Storage Sense was on, and now it's off. I had no idea Downloads was temporary, thank you so much for letting me know!! I think I can redownload the jar file from somewhere. Let me try that!

[u/N-M-1-5-6 → u/fishebake]

Also, the jar file you want might be inside the "original zip file" that you have? If so, you can unzip/extract the jar file from the zip file instead of re-downloading everything. Just a guess, but it might be worth checking if that's the case!

It says, can't find main class. You are probably missing manifest file. Put that error into Google AI, it will give you the solution
