Title: JmsConnectionFactory Configuration


A JmsConnectionFactory can be declared via xml in the `<tomee-home>/conf/tomee.xml` file or in a `WEB-INF/resources.xml` file using a declaration like the following.  All properties in the element body are optional.

    <Resource id="myJmsConnectionFactory" type="javax.jms.ConnectionFactory">
        connectionMaxIdleTime = 15 Minutes
        connectionMaxWaitTime = 5 seconds
        poolMaxSize = 10
        poolMinSize = 0
        resourceAdapter = Default JMS Resource Adapter
        transactionSupport = xa
    </Resource>

Alternatively, a JmsConnectionFactory can be declared via properties in the `<tomee-home>/conf/system.properties` file or via Java VirtualMachine `-D` properties.  The properties can also be used when embedding TomEE via the `javax.ejb.embeddable.EJBContainer` API or `InitialContext`

    myJmsConnectionFactory = new://Resource?type=javax.jms.ConnectionFactory
    myJmsConnectionFactory.connectionMaxIdleTime = 15 Minutes
    myJmsConnectionFactory.connectionMaxWaitTime = 5 seconds
    myJmsConnectionFactory.poolMaxSize = 10
    myJmsConnectionFactory.poolMinSize = 0
    myJmsConnectionFactory.resourceAdapter = Default JMS Resource Adapter
    myJmsConnectionFactory.transactionSupport = xa

Properties and xml can be mixed.  Properties will override the xml allowing for easy configuration change without the need for ${} style variable substitution.  Properties are not case sensitive.  If a property is specified that is not supported by the declared JmsConnectionFactory a warning will be logged.  If a JmsConnectionFactory is needed by the application and one is not declared, TomEE will create one dynamically using default settings.  Multiple JmsConnectionFactory declarations are allowed.
