Multicast address in code not getting set

I have the following code in my DDS program for java

DomainParticipantFactory.PARTICIPANT_QOS_DEFAULT. discovery.initial_peers.add("239.255.0.50");DomainParticipantFactory.PARTICIPANT_QOS_DEFAULT. discovery.initial_peers.add("4@builtin.udpv4://127.0.0.1");DomainParticipantFactory.PARTICIPANT_QOS_DEFAULT. discovery.initial_peers.add("builtin.shmem://");DomainParticipantFactory.PARTICIPANT_QOS_DEFAULT.discovery.multicast_receive_addresses.clear();DomainParticipantFactory.PARTICIPANT_QOS_DEFAULT.discovery.multicast_receive_addresses.add("239.255.0.50");

The setting of initial peers works correctly for the DDS code, however when I use the line to set the "multicast_receive_addresses" the address never gets set and keeps defaulting to the default multicast address. Why is my multicast address not getting set?

Hi Jason,

The proper way how to set initial_peers and multicast_receive_addresses programmatically in Java:

DomainParticipantQos qos = new DomainParticipantQos();
DomainParticipantFactory.get_instance().get_default_participant_qos(qos);
 
qos.discovery.initial_peers.clear();
qos.discovery.initial_peers.setMaximum(3);
qos.discovery.initial_peers.add("239.255.0.50");
qos.discovery.initial_peers.add("4@builtin.udpv4://127.0.0.1");
qos.discovery.initial_peers.add("builtin.shmem://");
 
 
qos.discovery.multicast_receive_addresses.clear();
qos.discovery.multicast_receive_addresses.setMaximum(1);
qos.discovery.multicast_receive_addresses.add("239.255.0.50");
 
 
participant = DomainParticipantFactory.TheParticipantFactory.
create_participant(domainId, qos, null, StatusKind.STATUS_MASK_NONE);
if (participant == null) {
    System.err.println("create_participant error");
}

Let me know if it is working for you.

Best,

Antonio
