The command used to run and store the Materia obtained (-that is, a listing of the Constructors, the Fields (i.e. variables, to you Fortran types!-), & the Methods of the particular Java 2 class that is being Reflect-ed upon), is: java SeeAEMateria >ActionEventMateria.txt ...of course, these listings are not ideally helpful as to details, and you may need a manual just to construct the Class that you are using Reflect to extract all this info from - that is, the exact constructor parameters are not always obvious, if a default 'ClassConstructor()' is not present in the particular class being examined. - Good Luck! and keep a good manual handy too. To help with the constructors, you might take a glance in the good Java 2 basic (but, very comprehensive! unlike say the Nutshell Guides, which exasperate by not putting all the stuff in one book) reference guide, "The Java Developers Almanac" by Patrick Chan... see link below, if this is a web page (& if not, remind me <hess1@bigfoot.com> to publish one! ;) [-R.
