Hi all,
I am trying to run (play) an audio (.mid) file from Applet. This applets picks the path from http protocol.
Initially this applet was not loading in browsers on some computers (IE 5 or 5.5). Actually this applet was compiled on J2SDK1.4.1 & was not loading on lower versions.
Now i have compiled this applet as below :
javac -target 1.1 RingtoneApplet.java
Now applet is started in browsers on every machine we have, but some browsers are not playing midi file.
Machine those having J2SDK1.4.1 are playing midi file perfectly (these were playing earlier also when compiled with J2SDK1.4.1).
But machine those having java versions lower than J2SDK1.4, are not playing midi (.mid) file, however applet is started. Their browsers java console gives error :
NativeAudioStream : invalid file type
Netscape Navigator shows the same error :
NativeAudioStream : invalid file type , even on the machines having version J2SDK1.4.1.
Can any one help me out, where is the problem.
Does system java/jre has anything to do with browsers java/jre.
(I am mainly concerned with IE 5.0, IE 5.5 , IE 4 series & latest one.)
Please help me out.

Thanks,
Manoj
