Jar file 101

Here is a very simple example. I have a very simple single class application called Frame2.
The manifest file tells jar which class file has the "Main-Class" directive to run. Note that this file needs to end with a new line character.

PS C:\Users\tjinkers\java\swing> ls Frame2.*
Directory: C:\Users\tjinkers\java\swing

Mode LastWriteTime Length Name
---- ------------- ------ ----
-a--- 22/01/2014 15:37 693 Frame2.class
-a--- 22/01/2014 10:20 377 Frame2.java

PS C:\Users\tjinkers\java\swing> cat .\manifest.txt
Main-Class: Frame2
PS C:\Users\tjinkers\java\swing> jar cvfm Frame2.jar manifest.txt Frame2.class
added manifest
adding: Frame2.class(in = 693) (out= 471)(deflated 32%)
PS C:\Users\tjinkers\java\swing> ls Frame2.*
