javac is the java compiler. jar is the command for creating a jar file from existing class files. However, if you have a lot of java files you need to compile, you will probably want to use a build tool like ant.



Using the jar command typically looks something like jar cvf somefile.jar *



That command will take all the files in the current directory and package them into a jar called somefile.jar. But again, that's a very simple example and real world software application packaging is likely to be more complicated.



Again, you probably want to use something like ant to manage the build and packaging process for you. Just do a google search for "apache ant". There are also tutorials on the ant web site to help you get started writing ant scripts.
