Java: Jar.exe: How to update a class in a .jar file? [replace]
===
Steps: Overview:
 1. -Possibly download and install the Sun Java SDK
     (as this installs the file jar.exe)
 2. -Open an MSDOS box and type the following command:
      jar.exe -uvf <your .jar filename> <your updated .class>
      E.g.
       jar.exe -uvf HelloWorld.jar HelloWorld.class
 3. -That will show a screen output similar to the following:
--- cut here: begin --------------------------------------------------
C:\> jar.exe -uvf HelloWorld.jar HelloWorld.class
     adding: HelloWorld.class (in = 544) (out= 347) (deflated 36%)
--- cut here: end ----------------------------------------------------
