Interesting problem for all students and programmers Have a look!

Question

Hello. This is a very interesting problem for all programmers and students. I have my spalsh screen class which displays a splash when run from the main method in the same class. However when run from another class( in my case from my login class, when user name and password is validated) I create an instance of the class and show it. But the image in the splash is not shown. Only a squared white background is visible!!!.
I am sending the two classes
Can u tell me why and propose a solution. Thanks.

private int duration;

// of the screen for the amount of time given in the constructor
public void showSplash() {
JPanel content = (JPanel)getContentPane();
content.setBackground(Color.white);
// Set the window's bounds, centering the window
int width = 300;
int height =400;
Dimension screen = Toolkit.getDefaultToolkit().getScreenSize();
int x = (screen.width-width)/2;
int y = (screen.height-height)/2;
setBounds(x,y,width,height);
// Build the splash screen

Hi Luis,
Use tcode XK99 for vendor mass change, select the Fax no field. You have to take note that this changes will be only 1 fax number for all vendors.
Else you have to use BAPI for mass change.
