View Full Version : Editing an application with .jar extension
May 3, 2013, 12:23 AM I have an application that was custom
built for me and I need to get into it to make some changes. The
file extension is .jar. I know that .jar files are just archive
files, but this is the file I launch to run the program. It
doesn't actually unarchive anything (afaik) but is the
pplication file itself.  Normally I could right click and "show
package contents" for most apps, but since this is a .jar file
that's not an option.  Any ideas on how to get at the code?  May

able to edit it, you'd see java byte code, which isn't practical
to edit by hand.  When you open a .app file, the code within it
is also already compiled (albeit machine code), which also isn't
practical to edit by hand.  You probably can't get from a .jar
back to the original .java any more than you could get back to
the original .c/.m/.cpp/.mm of a .app.  May 3, 2013, 12:59 AM
