Description gailizhao 1999-07-27 21:54:01 UTC
Hi,

I have an applet that performs a multicast function on a
Linux machine.  The browser is Netscape communicator 4.51.
The applet is a signed applet and has passed
the "Multicast" privilege checking when the applet is
executed. Right after the privilege checking, the applet
attempts to instantiate a multicastSocket with the
following code: DatagramSocket socket = new MulticastSocket
(6666); At this point, a SocketException occurrs.

The Stack traces are:
invalid DatagramSocket option
at java.net.PlainDatagramSocketImpl.setOption
(PlainDatagramSocketImpl.java:156)
at java.net.MulticastCreate (MulticastSocket.java:111)
at java.net.DatagramSocket. (DatagramSocket.java:115)
at java.net.DatagramSocket. (DatagramSocket.java:101)
at java.net.MulticastSocket. (MulticastSocket.java:92)
at inria.net.MulticastSession.run
(MulticastSession.java:205)  applet code
at java.lang.Thread.run (Thread.java:504)

Note: The same applet running with Netscape communicator
4.51 under Windows is OK.

Can someone tell me what's the cause of this problem?

Thanks.

Do you have multicast support compiled into your kernel?

Comment 2 Bill Nottingham 1999-08-24 16:38:59 UTC
Corfirmed and reported to Netscape. Unfortunately, since we
don't control the netscape source code, we can't really
fix this.
