getting two classes working together

hello.

this is james mcfadden. i am currently developing a video library system in Java. it involves developing a video library menu. the video library menu is supposed to consist of an administrator's section, a new user's section and an existing user's section. i am using JTabbedPane to navigate between the 3 sections of the menu. the following program compiles but it does not run the way i expect it to. when i run the program, the frame with the tabbed pane stuff is displayed on screen, but when i press any of the 2 Log On buttons the logon dialog box called "Welcome to Home Entertainment" doesn't display on screen. how can i solve this problem?

thanks.
