On your way in you may have missed that we have a policy on screen names here at JavaRanch. Basically, it must consist of a first name, a space, and a last name, and not be obviously fictitious. Since yours does not conform with it, please take a moment to change it before your next post; you can do right here.
Also, please CarefullyChooseOneForum. This one is for posting certification results, as its title implies. I'll move it to a more appropriate forum.
As to your question, you'll need to supply more detail about what you're trying to do. What is a "screen" - a mainframe-type green screen? A web page? The GUI of a desktop app? Something else entirely?
