Try this registry script:

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\SOFTWARE\Classes\.jar]
@="CompressedFolder"

For more information about this apparently undocumented `@` symbol, don't bother with the official MS docs, because it's not mentioned there. https://support.microsoft.com/en-us/kb/310516 Apparently it refers to the `Data` field of the `(Default)` key. – jordanpg May 04 '15 at 16:50

Jar (=Java Archive) are just zipped Java class files, so you can use any Zip-Archiver tool to unzip it, for example 7-zip.

It won't bring you much, however, because class files are the files compiled into bytecode, so this is a binary format you cannot easily look in. You can decompile these files using some of existing Java decompilers, for example this one.

Open them with 7-zip. If you really want to double click, set it as default program for .jar files.
