9.2.2 Application-managed EntityManager An application-managed EntityManager wants nothing to do with a Java EE container. This means that you must write code to control every aspect of the EntityManager s lifecycle. By and large, application-managed EntityManagers are most appropriate for environments where a container is not available, such as Java SE or a lightweight web container like Tomcat. However, a justification to use application-managed EntityManagers inside a Java EE container is to maintain fine-grained control over the EntityManager lifecycle or transaction management. For this reason, as well as to maintain flexibility, the EJB 3 API provides a few conveniences for using application-managed EntityManagers inside a container. This happens to suit us well too, because it provides an effective approach to exploring application-managed EntityManagers (see listing 9.2) by reusing the code in listing 9.1. how to generate qr code in asp.net core QR Code Generator in ASP .

The customer class should not need to be aware of all the data-integrity rules that other classes in the application impose Modifying the customer class to take these data-integrity rules into account restricts the possibilities of reusing the class in other situations In other words, once the customer class implements any functionality that is linked to a different class, customer is no longer independently reusable, in many cases Despite the fact that the customer class is not the ideal place to implement this referential-integrity rule, many object-oriented programs work this way for lack of a better solution You might be thinking about integrating this functionality into an order class instead, but this solution is no better No reason exists for the order class to allow the deletion of a customer. asp.net core qr code generator Enable QR Code generation for TOTP authenticator apps in ASP ...

NET Core Barcode is a Portable Class Library (PCL) available in the ConnectCode Barcode Fonts ... The Classic Desktop or ASP . ... we will read in this data and then use the NET Core Barcode PCL to encode it ( generate barcode characters). It should be fairly obvious that we are more or less explicitly doing what the container did for us behind the scenes in listing 9.1. First we inject an instance of EntityManagerFactory b. We create an EntityManager using the injected entity manager factory after the bean is constructed C and close it E before the bean is destroyed, mirroring what the container does automatically. The same is true when we explicitly join a container-managed JTA transaction D before performing an EntityManager operation. EntityManagerFactory As you can see in listing 9.2, we get an instance of an application-managed EntityManager using the EntityManagerFactory interface. If you have used JDBC, this is essentially the same idea as creating a Connection from a DriverManager factory. In a Java EE environment, you have the luxury of using the @PersistenceUnit annotation to inject an instance of an EntityManagerFactory, just as we do in listing 9.2. This useful annotation is defined as follows: When an EJB client retrieves or creates an EJB reference, the EJB container provides a stub object reference that points to the actual bean. That means that the @Target({TYPE, METHOD, FIELD}) @Retention(RUNTIME) public @interface PersistenceUnit { String name() default ""; String unitName() default ""; } The name and unitName elements serve exactly the same purpose as they do for the @PersistenceContext annotation. While the name element can be used to point to Strictly speaking, this rule is linked to neither the customers nor the orders but cuts across these two types of entities One of the aims of dividing the data into classes is making the classes independent from one another However, crosscutting functionalities, such as the rules of referential integrity, appear superimposed on the division violating the independence of the classes In other words, OOP does not allow you to neatly implement crosscutting functionalities As a compromise, you can resign yourself to implementing them in individual classes, but remain conscious that this solution is not ideal.. reference contained by the client is actually a reference to the EJB stub object used by the container. Therefore, if you have more than one reference to an EJB, you could have two different stub objects that reference the same EJB. If you were to compare the references using the equals() method, it might return false, even if the stubs point to the same EJB. To solve this problem, EJB references implement the isIdentical() method. This method compares the two objects (the invoker and the parameter) to see if they both eventually point to the same EJB (through the stub). Figure 9.5 These relationships exist between various important classes in the javax.persistence package for using JPA outside the Java EE container. asp.net core qr code generator Enable QR Code generation for TOTP authenticator apps in ASP ...
