Make jar file copy itself

Question

I am trying to make my main executable jar file copy itself to another location.

How can I do this?

Does it know from an external source where it is, or does it have to find out itself? Also, can you explain in a few words what you're using this for? — us2012, Jan 09 '13 at 03:17
@us2012 No, it does not know where it is. Its kind of hard to explain what this is for, but basically on windows I need to copy it to appdata and on mac to library. — user1947236, Jan 09 '13 at 03:20
What is the problem? Do you have difficulties in how to copy with Java or how to find the jar-location? If the jar would copy a different jar - what would be the difference? How is the Program in the jar started? — user unknown, Jan 09 '13 at 03:25
@userunknown I know how to copy the file, I need help getting its location. — user1947236, Jan 09 '13 at 03:27

@archer Would that also get the name of the running jar file? — user1947236, Jan 09 '13 at 03:32
You should adjust the headline of your question to its goal. — user unknown, Jan 09 '13 at 03:48

return new File(MyClass.class.getProtectionDomain().
 getCodeSource().
 getLocation().
 getURI().
 getPath()).getName();

will return a full name

That seems to work. Do you know if there is a way I can get the name of an EXE that the jar is wrapped in? – user1947236 Jan 09 '13 at 03:52
