I'm currently using the sun.audio package to play audio files in my application composed of servlets and jsps, code would be something simple as follows in my servlet
My application has a number of tabs, the tab for playing audio for example, is called audioPlay and contains the code above. My problems are:
(1) selecting a different browser tab, while audio is playing, within my application, the audio still continues playing, I cannot stop it.
(2) Selecting the back browser on the web application, while the audio is running, the audio doesn't stop and is still running.
I've seen on a number of web-sites that clicking on a song title, goes into a servlet and plays the song in background which is what I have presently, but when they do steps 1 and 2 above within their website, the audio stops but doesn't in mine, are there any suggestions about how to solve this? I need to call Audioplayer.player.stop(as) at some stage, would using a class with static variables and start and stop options be a possibility? I hope I have made my issue clear or could this be an issue with the cache-control header? Thanks for any help returned.
Where did you get the classes like AudioStream and AudioPlayer. Do you have another jar?
I know one package from sun that is Java Sound API (previously it used to get included in JMF - Java Media Framework). Not very sure, but I think now it comes along with SDK itself.
You can read more about it here.
I've tried that package, thanks for advice, the sun.audio only works up to 16 bit audio, no problem with the Java Sound API. I have audio streaming on my localhost computer on my localhost website but now I have an issue when I try to point to the file from a different pc, meaning trying to access the web-site from a different computer through the web, nothing is happening I can't get the sound file to play. I have a servlet like this to point to the file
And a class to run this file, but no sound plays when trying to access file, from different PC through ip address of hosting PC. This does load and play on the Pc where the sound file is hosted, by using localhost.
This could be a generic issue just as well. Any help much appreciated.
This is not a good idea. How will you know if there's a problem? At least log the error message somewhere where you'll see it.

Thanks Tim. I have those error checks in my servlet that calls the class to stream the audio, but no errors are created. There's no problem running the project on my local Pc and the sound plays grand in the application, it's just when accessing the web-site from different PC, it is like the file is not loading and playing, I get no sound. Is there any chance it is an issue with the sound player used by the package "javax.sound.sampled"? As regards not being a good idea, any other alternatives or suggestions are extremely appreciated, thanks very much.
If your servlet is starting the sound then it will run on the server, not on the client / in the browser. To run it in the browser you need a) an applet where you can use its methods to start / stop the sound, b) embed it using HTML5's <audio> tag, or c) use the "old" <embed> tag to embed it.
