On your way in you may have missed that we have a policy on screen names here at JavaRanch. It must consist of a first name and a last name, and not be obviously fictitious. Since yours does not conform with it, please take a moment to change it, which you can do using the "My Profile" link at the top of the page.
As to your question, what is "a problem"? TellTheDetails. You don't need to download that; it's part of the JRE.
