Hi,
I have an applet that performs a multicast function on a Linux machine.
The browser used 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.
