You can create as many appenders as you need in a log configuration file, and you can assign as many appenders to a single logger as you want. Each appender is independent of any others assigned to the same logger; each log message is reproduced and sent through each appender on its list.

This is because the remove method can only delete currently attached entities and the Item entity being passed to the deleteItem method is not managed. If a detached entity is passed to the remove method, it throws an IllegalArgumentException. Before the deleteItem method returns, the Item record will be deleted from the database using a DELETE statement like this:

Just as with the persist and merge methods, the DELETE statement is not necessarily issued immediately but is guaranteed to be issued at some point. Meanwhile, the EntityManager marks the entity as removed so that no further changes to it are synchronized (as we noted in the previous section). Cascading remove operations Just as with merging and persisting entities, you must set the cascade element of a relationship annotation to either ALL or REMOVE for related entities to be removed with the one passed to the remove method. For example, we can specify that the BillingInfo entity related to a Bidder be removed with the owning Bidder entity as follows:

Before you can begin sending messages through the logging system, you must initialize the logging framework with a configuration. For example, to initialize the brokerage application with the previous configuration file, your application must use the org.apache.log4j.PropertyConfigurator class. The following code demonstrates:

@Entity public class Bidder { @OneToOne(cascade=CascadeType.REMOVE) public BillingInfo setBillingInfo() {

Aspect configuration is an essential task when programming with JAC. This feature is not often provided by other AOP environments, such as AspectJ, although it is a key factor when reusing aspects. Each aspect that is defined with JAC is associated with an aspect-configuration file. You choose the parameters that are to be configured in the aspect. The end user defines the aspectconfiguration file and the values that are associated with these parameters. For example, when using a transaction-demarcation aspect, you must indicate the methods that are to be executed in the transaction. When using a persistence aspect, you must designate the attributes that are to be saved in a database. The principle of an aspect-configuration file exists in other approaches, such as that of J2EE. The idea is to separate the code from the initialization values that are used by the code. The code can then be reused without any modifications or recompilations, whereas the initialization values will depend on the execution context. J2EE and JAC share the same principle however, the way that they deal with the configuration process differs. In both cases, a set of parameters is associated with the persistence, transaction, naming, and access-control services. With J2EE, these parameters are provided by the servers, are
