SIS files are Symbian and JAR files are java. The software that converts a SIS file to a JAR file is called Sis to Jar Converter 1.7.7.2.
The most usual way is by way of the jar command. The jar command takes a series of inputs, usually a set of class files and folders that represent the binaries (.class, images, audio files, etc) files you wish to combine into a single jar file. The example given by Oracle on the command is as follows: jar cvf TicTacToe.jar TicTacToe.class audio images This takes the TicTacToe.class file, the folder audio, and the folder images, and combines them into the TicTacToe.jar file. The parameters cvf stand for "create", "verbose output", and and "file output"; these are the most common parameters when creating a jar file. For details, see the attached link.

JAR stands for JAVA Archive File. You can archive a number of java class files into an archive and form a JAR. If you place the JAR in a particular location in the computer and then add the path to the JVM Class path, the JVM will be able to recognize references to classes that are present in the JAR.
JAR files are basically ZIP files, so you can open them by any software that can work with ZIP files. That includes Windows XP default file-system browser, WinZip, etc. To actually run the JAR archive, you need to have JAVA runtime environment installed on your computer.
I believe a jar takes up less memory but requires java to run exe and jar (although a jar is similar to a zip file) can NOT be run on Mac software.
