im sure both your nifty lil compilers have a readme or help file, as for me on the other hand i use JCreator :D i find the "Create Jar File" option on the tools menubar very useful :D

Just create it on the command line, or better use Ant.If you need to use an IDE do as sosleepy suggested and read the help or post your question on the correct forum.
