Corrupted jar file
I "converted" the jar file into a zip folder
and then to a normal folder. I opened the MANIFEST.MF file with the text editor. Then I closed it and made the folder to a jar file. When I double clicked the jar file, it says "corrupted jar file". I don't know why; is it because I opened the MANIFEST file with the text editor or why?

Then I closed it and made the folder to a jar file. How did you do this, with thejarcommand or something else? You can also tryjar tvf filename.jarto see if it gives you any additional output or hints.

If I understood right, your new jar contains a redundant folder because you zipped the folder, but what you had to do is to zip only content of that folder.

In the future, you can use the jar command to remove files and add them back into a jar.
List all files in the jar:
jar tvf application.jar
Extract a file from the jar:
jar xvf application.jar path/of/file/to/extract
Add a file back into the jar:
jar uvf application.jar path/of/file/to/extract
MANIFEST files get a little special handling. If you want to add it back in:
jar uvfm application.jar mymanifest
Note: In all the commands above the v flag is used to provide verbose feedback from the command and can be omitted if you want.
