hi once again
i have been trying to figure out why my tomcat native based mina
acceptor won't join a speicified multicast group. the call goes through
Multicast.join() over the tomcat native code to apr_mcast_join which in
turn calls do_mcast in the apr multicast.c file. then it goes to os
specific code, and in the end i get APR_SUCCESS back. but wether when
specifying an iface of 0 (use default) nor when giving a specific
interface does anything actually happen. no igmp message is sent and no
multicast group is joined. has anyone ever had similar problems, or has
anyone used the apr multicast code successfully on win32 machines?
Try Multicast.loopback if Multicast.join fails.
Win32 is pretty weired, and not sure why the join doesn't work.
I suppose the multicast group needs to exists before joining.
