Adding Background with NetBeans

Question

I am new to NetBeans and currently am trying to add a cycling background. Is there a way to do this. Also, I have changed the font of one of my JLabel, but it still shows the font first used instead of the one I have recently changed it too. I look at the code and it is also specified to the one I want it to be. Any way to fix this?
Thanks

Answer 1

Alright I have tried a majority of different ways, but I am still unable to get this JMF media player to compile and work. I have a combo box that once selected will go play a file of that specific genre. I want to set the media player to be visible on the JForm once played, but am unsuccessful at that as well. I have read through forums and looked at the JMF tutorial with no success, so I am hoping I can get some answers here. I also can't get my font to display as it should be. Any suggestions? I appreciate it so much for anyone taking the time to look at this.
Here is the code...
