I show these three audio files on the JSP page, just as following show.
The script I used to show these audio files is like this:
<script language="JavaScript">
document.write(' <object width="320" height="45"
classid="CLSID:22D6F312-B0F6-11D0-94AB-0080C74C7E95">');
document.write(' <param name="filename"
value="getParts.jsp;jsessionid=87ACD9BD3590FBE1051F33B2AA7AE488?timestamp=1260252638867&contentid=137063&timemark=20091110&index=4"
/>');
document.write(' <PARAM NAME="AUTOSTART" value="false">');
document.write(' <embed width="320" height="45"
type="application/x-mplayer2"
src="getParts.jsp;jsessionid=87ACD9BD3590FBE1051F33B2AA7AE488?timestamp=1260252638867&contentid=137063&timemark=20091110&index=4"
AutoStart="0">');
document.write(' </embed>');
document.write(' </object>');
</script>
I select the icon of Ashanti.WAV, and press the right key of mouse, and it show
the menu like this:
After I pressed the menu item “Properties”, a dialog box will show, and we see
the Location of the audio file.
We can see that, jsessionid= 87ACD9BD3590FBE1051F33B2AA7AE488, but after I
pressed the “play” button of the audio file, it doesn’t work. That is, this
file can’t be played.
I traced in the log file, and found the real session id is
1FADDAF2B01872E5E8ECEB72C72BF98C.
Each time I pressed the play button, there are two lines added in the log, like
this:
TRACE 091208 17:19:25,476 http-8080-8
sessionid:1FADDAF2B01872E5E8ECEB72C72BF98C
WARN 091208 17:19:25,476 http-8080-8 message from session is null!
So I can make sure that, there is something wrong with the session information.
I have tested this for lots of times with the browser FireFox3.5, and it always
works like this.
But if I change to use IE6/IE7/IE8, this problem never happened. Does someone
know the reason? thanks.

Seems like a propietary way of storing the session ID, I'm not much into JSP
stuff so I really don't know. Someone else here may be able to explain.
You can store whatever you need in parameters, either by putting into URLs or
by creating (hidden) controls on web forms. This is the preferred method of
parameter passing, as it allows multiple instances (e.g. browser tabs) to
coexist. You should only store things in a session that are related to the
connection and user (e.g. user credentials, preferences and such), but
absolutely not the page he's navigating now.
You can also add a "path" to the URL, e.g.
getparts.jsp/137063/4
Then "getPathInfo()" will return "137063/4" in getparts.jsp.
