Help Needed!?#?!@!!!!!- java.lang.IllegalThreadStateException !!!!!!!
I'm building an mp3 player and a bit new to threading concepts. I have created a JDialog box which contains a FileChooser, which is supposed to pop up as soon as i click the Open button in my ui. I have initialized the object of the JDialog in the Oen Button's ActionListener method.
On compliling and running the ui comes up but on clicking the open button it doesn't respond.
