Obtaining the Client Identifier
You can either hard code the client identifier of the recipient, if it is well known, or you can extract the identifier from a event that you have received from the Broker client as shown in the following example.
. . .
BrokerEvent e;
String client_id;
. . .
try {
client_id = e.getStringField("_env.pubId");
} catch (BrokerException ex) {
System.out.println("Error on getting destination ID\n"+ex);
return;
}
. . .
