Re: what the problem about this short code?

it says that Cannot find a Player for :file:\d:\music\11.wma.what
the problem?
I don't know about media players, but I have a couple of suggestions.
First, importing any java.lang.* class is redundant in a bad way: it
doesn't affect the meaning of the program, but it leaves a reader of
the code looking for an explanation.
Second, never write
new String("foo")
for any literal "foo". Instead, write just
"foo"
and it will be a perfectly adequate String. Or if you are trying to
appear paranoid, consider something like this:
(String)new String(new String((String)((String)"foo").toString()))
Well, just don't.
Third, and this may actually help you, you can write an even simpler
test program and so eliminate some possibilities of error:
import javax.media.Manager;
import javax.media.bean.playerbean.MediaPlayer;
public class Player1 {
public static void main(String[] args) {
MediaPlayer mp1 = new MediaPlayer();
mp1.setMediaLocation("file:\\d:\\music\\11.wma");
mp1.start();
}
}
Oh, and please, include the actual error message. Cut and paste, or
otherwise copy it _exactly_. Any paraphrase is likely to distort it
when you don't already know what the message means.
