[jboss-user] [Beginner's Corner] - Communication between AppServer and Client via multicast

[boltimuss]

Hello forums, I am new to the forums and to JBOSS. I am trying to write an mBean that will communicate from within the AS across a multicast channel using JGroups. The code I'm using in my mBean is below...


  | public void create() throws Exception {
  |     channel=new JChannel("test/udp.xml");
  |     channel.connect("ChatCluster");
  |   }
  | 
  | public void sendMsg() throws ChannelNotConnectedException,  
  |                                            ChannelClosedException {
  |      channel.send(new org.jgroups.Message(
  |                          null,null, "hello from the server!"));
  |   }
  | 


I also created a client that is listening on the channel, but the two are not communicating .. Here is the XML for the channel ..


  | <UDP
  |          mcast_port="45700"
  |          mcast_addr="224.0.0.11"
  |          tos="8"
  |          ucast_recv_buf_size="20000000"
  |          ucast_send_buf_size="640000"
  |          mcast_recv_buf_size="25000000"
  |          mcast_send_buf_size="640000"
  |          loopback="true"
  |          discard_incompatible_packets="true"
  |          max_bundle_size="64000"
  |          max_bundle_timeout="30"
  |          ip_ttl="${jgroups.udp.ip_ttl:32}"
  |          enable_bundling="true"
  |          enable_diagnostics="true"
  |          thread_naming_pattern="cl"
  | 
  |          thread_pool.enabled="true"
  |          thread_pool.min_threads="2"
  |          thread_pool.max_threads="8"
  |          thread_pool.keep_alive_time="5000"
  |          thread_pool.queue_enabled="true"
  |          thread_pool.queue_max_size="10000"
  |          thread_pool.rejection_policy="discard"
  | 
  |          oob_thread_pool.enabled="true"
  |          oob_thread_pool.min_threads="1"
  |          oob_thread_pool.max_threads="8"
  |          oob_thread_pool.keep_alive_time="5000"
  |          oob_thread_pool.queue_enabled="false"
  |          oob_thread_pool.queue_max_size="100"
  |          oob_thread_pool.rejection_policy="Run"/>
  | 

Any help would be greatly appreciated as I have spent some tie on this and am trying to figure this out. I would prefer to use some other echanism for communication, however I am limited to just using multicast ... long story..

Thanks!!!
