= JmsConnectionFactory Configuration
:index-group: Unrevised

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.
[source,xml]
----
<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`
[source,properties]
----
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. # Supported Properties
