Home Flex Login.mxml

This is a small example of Login screen in flex, we assume that the userid should be roseindia and password is abc, if someone enter wrong id or password or just hit the submit button, an alert message will be displayed, if both the userid and password would correct then an welcome message in alert box will be displayed.
