Opening an mp3 file in the default external player.

Hi, i am having a problem opening an mp3 in the systems default player. I dont want the mp3 to be launched with the program but with the systems media player (e.g. vlc, windows media player, winamp etc whatever it may be)

here is the code i am currently using:

String tempFile = f.getAbsolutePath();
tempFile = tempFile.replaceAll("%20"," ");
File temp = new File(tempFile);
document = temp;

Desktop dt = Desktop.getDesktop();
dt.open(document);

the error i get is this:

java.io.IOException: Failed to open file:/C:/Users/matt/Documents/NetBeansProjects/theProject/test.mp3. Error message: Unspecified error

any suggestions? am i doing it wrong? been stuck on this for a solid hour now and google searching hasnt helped :( thx for any help :frusty:

Please post the FULL text of the error message. It has information. Like what line did the error occur on.

Also where is the variable: document defined? Add a println to print out the value of document before it is used by the open() method.

private File document;

at the start just under the class it is ok the variables are fine and im sorry here is the rest of the error:

here is the output from some printlns i added

System.out.println("Document: "+ document);
System.out.println("Document getAbsolutePath: "+ document.getAbsolutePath());
System.out.println("Document getCanonicalPPath: "+ document.getCanonicalPath());
System.out.println("Document getPath: "+ document.getPath());
System.out.println("Document getName: "+ document.getName());

==

Document: C:\Users\matt\Documents\NetBeansProjects\theProjec t\downloads\Test.mp3
Document getAbsolutePath: C:\Users\matt\Documents\NetBeansProjects\theProjec t\downloads\Test.mp3
Document getCanonicalPPath: C:\Users\matt\Documents\NetBeansProjects\theProjec t\downloads\Test.mp3
Document getPath: C:\Users\matt\Documents\NetBeansProjects\theProjec t\downloads\Test.mp3
Document getName: Test.mp3

what i have noticed is that the file:/ part is only one /

try entering that into something like ie or chrome or firefox it should correct it to have file:///

do you think that could be the problem? and how would i fix that because it isnt in the filepath i am feeding it.

Try using another file like a .txt file and see what happens. Maybe the OS doesn't know what to do when Java asks it for the program for .mp3 files.

hmm i think you are correct, when the extension is .txt it opens in notepad with no problems at all , shame.

I guess ill just have to open it with windows media player lol
