How do you decompile a JAR and edit it?

Before opening jar file just change the extension of jar to zip file and then extract that particular class file that you want to edit , then decompile it using any decompiler ,make the changes , compile it back and then finally put it back in the zip file. Hope it helps.

How do I open a jar file with edit code?

A jar file is a zip archive. You can extract it using 7zip (a great simple tool to open archives). You can also change its extension to zip and use whatever to unzip the file.

Here's what I did:

  • Extracted the files using WinRAR
  • Made my changes to the extracted files
  • Opened the original JAR file with WinRAR
  • Used the ADD button to replace the files that I modified

That's it. I have tested it with my Nokia and it's working for me.
