Paint from a console

Question

i i have a program that load thigns from the db, and draw on a panel and save it to a file without user interaction, is there possible to do the same things but in console mode, just type java program_name and taht does the same things, dont seems to work always get a empty picture.. is there because im in console mode (its not possible to make a jpanel but visible false!?)
thx

Answer 1

i dont get confuse, its my question
i know that console its not gui and gui its not console
but can i make a gui not visible program that can run on console
or like make a panel object, draw on it, without display it to the user, like setVisible(false)
sorry i have problem to explain it in english
check i use this code:
the class objectcloner is ok, and JP make my draw
all this work perfectly with the gui, but isntead of using actionPerformed with the combobox, i would like to pass the data i need in arguments with no graphics in my console windows
(and instead of using JFileChooser pass the file in arguments too)
do you have a idea now what i want?
sorry for my english
