Title: CmpEntityContainer Configuration


A CmpEntityContainer 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.

    <Container id="myCmpEntityContainer" type="CMP_ENTITY">
        cmpEngineFactory = org.apache.openejb.core.cmp.jpa.JpaCmpEngineFactory
    </Container>

Alternatively, a CmpEntityContainer 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`

    myCmpEntityContainer = new://Container?type=CMP_ENTITY
    myCmpEntityContainer.cmpEngineFactory = org.apache.openejb.core.cmp.jpa.JpaCmpEngineFactory

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 CmpEntityContainer a warning will be logged.  If a CmpEntityContainer is needed by the application and one is not declared, TomEE will create one dynamically using default settings.  Multiple CmpEntityContainer declarations are allowed.
