Linda described how EJB's container-managed transactions can be applied to the Java EE 7 platform
as a whole using a solution based on CDI interceptors. This can then be used by other Java EE components
as well, such
as Managed Beans.
The plan is to add an annotation and standardized values in the javax.transaction package. For example:
@Inherited
@InterceptorBinding
@Target({TYPE, METHOD})
@Retention(RUNTIME)
public @interface Transactional {
TxType value()
default TxType.REQUIRED
}
And then this can be specified on a class or a method of a class as:
public class ShoppingCart {
...
@Transactional
public void checkOut() {...}
...
}
This interceptor will be defined
as part of the update to Java Transactions API spec at jta-spec.java.net.
