To configure Seam's infrastructure for sending JMS messages, you need to tell Seam about any topics and queues you want to send messages to, and also tell Seam where to find the QueueConnectionFactory and/or TopicConnectionFactory.

Seam defaults to using UIL2ConnectionFactory which is the usual connection factory for use with JBossMQ. If you are using some other JMS provider, you need to set one or both of queueConnection.queueConnectionFactoryJndiName and topicConnection.topicConnectionFactoryJndiName in seam.properties, web.xml or components.xml.

You also need to list topics and queues in components.xml to install Seam managed TopicPublishers and QueueSenders:

<jms:managed-topic-publisher name="stockTickerPublisher" auto-create="true" 
    topic-jndi-name="topic/stockTickerTopic"/>

<jms:managed-queue-sender name="paymentQueueSender" auto-create="true" 
    queue-jndi-name="queue/paymentQueue"/>
