Am not sure how can I respond to an "answer" given by user "reportdev". So please excuse me for that.
User "reportdev" thank you for your quick response, really appreciate it.
But, it seems like this is for a desktop application. There would be some ways to show the JFrame on a webpage, but am thinking taking JFrame on web page would not be best, although it might work.
