Examples of org.apache.qpid.util.ConversationFactory

org.apache.qpid.util.ConversationFactory

ange greetings. conversation.send(sendDestination, conversation.getSession().createTextMessage("Hello.")); Message greeting = conversation.receive(); // Exchange goodbyes. conversation.send(conversation.getSession().createTextMessage("Goodbye.")); Message goodbye = conversation.receive(); } finally { conversation.end(); } } } class Responder { ConversationHelper conversation = new ConversationHelper(connection, receiveDestination, java.util.concurrent.LinkedBlockingQueue.class); respondToConversation() { try { // Exchange greetings. Message greeting = conversation.receive(); conversation.send(conversation.getSession().createTextMessage("Hello.")); // Exchange goodbyes. Message goodbye = conversation.receive(); conversation.send(conversation.getSession().createTextMessage("Goodbye.")); } finally { conversation.end(); } } }

Conversation correlation id's are generated on a per thread basis.

The same controlSession is shared amongst all conversations. Calls to send are therefore synchronized because JMS sessions are not multi-threaded.

CRC Card
Responsibilities	Collaborations
Associate messages to an ongoing conversation using correlation ids.
Auto manage sessions for conversations.
Store messages not in a conversation in dead letter box.
