Title: SingletonContainer Configuration A SingletonContainer can be declared via xml in the `/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. accessTimeout = 30 seconds Alternatively, a SingletonContainer can be declared via properties in the `/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` mySingletonContainer = new://Container?type=SINGLETON mySingletonContainer.accessTimeout = 30 seconds 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 SingletonContainer a warning will be logged. If a SingletonContainer is needed by the application and one is not declared, TomEE will create one dynamically using default settings. Multiple SingletonContainer declarations are allowed. # Supported Properties
Property Type Default Description
accessTimeout time 30 seconds Specifies the maximum time an invocation could wait for the `@Singleton` bean instance to become available before giving up.
## accessTimeout Specifies the maximum time an invocation could wait for the `@Singleton` bean instance to become available before giving up. After the timeout is reached a `javax.ejb.ConcurrentAccessTimeoutException` will be thrown. Usable time units: nanoseconds, microsecons, milliseconds, seconds, minutes, hours, days. Or any combination such as `1 hour and 27 minutes and 10 seconds` Any usage of the `javax.ejb.AccessTimeout` annotation will override this setting for the bean or method where the annotation is used.
