problem using JMF code
hello.
this is james mcfadden. i am having trouble trying to use 2 JMF programs (MediaPanel.java and MediaTest.java) with the Demo.java program. the Demo.java program compiles and runs ok, but when i press 1 (for listening to songs) in the media menu i get a JOptionPane (An Error Message) displayed on screen. how can i fix this problem?
