A jar file is just a zipped file. It can be manipulated by any zip uptility. For instance, I use a tool called "File Librarian" and I sometimes use WinZip. Each of these allow me to select one of the files in the jar, and extract only it. Then I make my changes delete the old version of the file, and add the new version back in.
