  • Configure changes for applications that use Hibernate and JPA
  • Update your Hibernate 3.x application to use Hibernate 4
  • Changes for Hibernate 3.3 applications

  • Changes for Hibernate 3.5 applications
  • if your application uses Hibernate 3 classes that are not available in Hibernate 4, for example, some of the validator or search classes, you may see ClassNotFoundExceptions when you deploy your application. If you encounter this problem, you can try one of two approaches: You may be able to resolve the issue by copying the specific Hibernate 3 JARs containing those classes into the application "/lib" directory or by adding them to the classpath using some other method. In some cases this may result in ClassCastExceptions or other class loading issues due to the mixed use of the Hibernate versions, so you will need to use the second approach. You need to tell the server to use only the Hibernate 3 libraries and you will need to add exclusions for the Hibernate 4 libraries. Details on how to do this are described here: JPA Reference Guide.
  • In previous versions of the application server, the JCA data source configuration was defined in a file with a suffix of *-ds.xml. This file was then deployed in the server's deploy directory. The JDBC driver was copied to the server lib/ directory or packaged in the application's WEB-INF/lib/ directory. In AS7, this has all changed. You will no longer package the JDBC driver with the application or in the server/lib directory. The *-ds.xml file is now obsolete and the datasource configuration information is now defined in the standalone/configuration/standalone.xml or in the domain/configuration/domain.xml file. A JDBC 4-compliant driver can be installed as a deployment or as a core module. A driver that is JDBC 4-compliant contains a META-INF/services/java.sql.Driver file that specifies the driver class name. A driver that is not JDBC 4-compliant requires additional steps, as noted below.
  • DataSource Configuration
  • domain mode, the configuration file is the domain/configuration/domain.xml
  • standalone mode, you will configure the datasource in the standalone/configuration/standalone.xml
  • MySQL datasource element:
  •         <connection-url>jdbc:mysql://localhost:3306/YourApplicationURL</connection-url>        <driver-class> com.mysql.jdbc.Driver </driver-class>        <driver> mysql-connector-java-5.1.15.jar </driver>
  •        <security>            <user-name> USERID </user-name>            <password> PASSWORD</password>        </security>
  • example of the driver element for driver that is not JDBC 4-compliant. The driver-class must be specified since it there is no META-INF/services/java.sql.Driver file that specifies the driver class name.
  •  <driver-class>com.mysql.jdbc.Driver</driver-class>
  • JDBC driver can be installed into the container in one of two ways: either as a deployment or as a core module
  • Install the JDBC driver
  • Install the JDBC driver as a deployment
  • In AS7 standalone mode, you simply copy the JDBC 4-compliant JAR into the AS7_HOME/standalone/deployments directory
  • example of a MySQL JDBC driver installed as a deployment:     AS7_HOME/standalone/deployments/mysql-connector-java-5.1.15.jar

Enterprise JavaBeans 3.1 with Contexts and Dependency Injection: The Perfect Synergy - 0 views

  • stateless EJB 3.1 bean as boundary (Facade)
  • injected managed beans (controls)
  • @Inject
  • ...22 more annotations...
  • @Inject
  • CDI managed beans. The @EJB annotation is removed and @Inject is used instead
  • Annotating the boundary (Cart) with the @Named annotation makes the Cart immediately visible for expression language (EL) expressions in JSP and JSF
  • @Named annotation takes the simple name of the annotated class, puts the first character in lowercase, and exposes it directly to the JSF pages (or JSP). The Cart bean can be accessed directly, without any backed or managed beans, by the JSF pages: <h:commandButton value="Check out!" action="#{cart.checkout}" />
  • If there is a need for abstraction, the class can be turned into an interface (or abstract class)
  • local implementation (with CDI events
  • @Inject Event<String> event;
  • event.fire("Order proceeded!");
  • remote implementation:
  • javax.enterprise.event.Event belongs to the CDI-implementation
  • class Event can be considered to be a lightweight alternative to the java.beans.PropertyChangeSupport class
  • @Inject Event<String> event;
  • event.fire("Order proceeded!");
  • event can be received by any managed bean and also by EJB beans
  • provide a method with a single @Observes annotated parameter
  • @Observes String event
  • there is no real event, just the payload:
  • The during attribute in the @Observes annotation allows you to select in which transactional phase the event gets delivered. The default setting is IN_PROGRESS, which causes an immediate event delivery regardless of the transaction outcome. The AFTER_SUCCESS configuration causes the delivery to occur only after successful transaction completion
  • Although CDI events work only inside a single process (in the default case, CDI is extensible), they are perfectly suitable for decoupling packages from modules
  • The method checkout() starts a transaction that gets "reused" by the OrderSystem and CustomerNotification session beans
  • ordering.placeOrder(); notifier.sendNotification();

      both run within same transaction
  • EJB beans cannot be directly exposed to JSF or JSP without a little help from CDI

      example of dependencies *between* permissions. eg, in this case, work-on-issues permission 'needs' browse-projects permission could be expressed as a permission hierarchy where if work-on-issues permission is granted, means/implies that user already has browse-projects permission (w-o-i perm 'subsumes' b-p perm) might imply permission hierarchy

  • “Interfaces are used to encode similarities which the classes of various types share, but do not necessarily constitute a class relationship. For instance, a human and a parrot can both whistle; however, it would not make sense to represent Humans and Parrots as subclasses of a Whistler class. Rather they would most likely be subclasses of an Animal class (likely with intermediate classes), but both would implement the Whistler interface.” [http://en.wikipedia.org/wiki/Java_interface]

graniteds flex actionscript3 as3 bean validation

shared by kuni katsuya on 06 Jun 12 - No Cached
  • Bean Validation for Flex developers
  • GraniteDS have added support for Bean Validation into their project and hence Bean Validation is usable by all Flex users
  • Because they do not run on the JVM, they basically have reimplemented the full specification in Flex: you can annotate your ActionScript3 objects with constraints: it supports all the standard constraints and you can write your own constraints you can execute the validation logic and retrieve the error report you can make use of most of the feature including advanced ones like groups, group sequence etc
  • ...3 more annotations...
  • for GraniteDS users keeping their Java domain model and ActionScript3 domain model in sync via Gas3, the constraints are kept in sync
  • a couple of gotchas to be aware of
  • the constraint implementation is in the same class as the constraint declaration (not a problem in a dynamic language) @Pattern has a sightly different semantic because the regexp engine in Flex is a bit different. instead of the features provided by ConstraintValidatorContext, you can define a properties attribute in your constraints to make it belong to several sub-properties. not as flexible but good enough in many cases.

      gold! :)
  • to reproduce the same awful patterns
  • please not this Dao/Template mess
  • Because, of course, there are no other well-known patterns for dealing with boiler-plate cleanup code and connection leaks.

      platinum!!!
  • It gives people a
  • half-assed solution
  • and somehow shuts down their brains so they
  • stop asking themselves how this solution could be improved upon
  • It's a very impressive magic trick, and I wish I knew how to do it myself. But then, I'm just not like that. I'm always trying to poke holes in things - whether they were Invented Here or Not.
  • but that might be too high-level for your taste. Their are other, less-abstract options.
  • exception handling, this is one area where Spring does a good job: "The Spring Framework's handling of SQLException is one of its most useful features in terms of enabling easier JDBC development and maintenance. The Spring Framework provides JDBC support that abstracts SQLException and provides a DAO-friendly, unchecked exception hierarchy."
  • Utter nonsense and dishonest false advertising
  • Automatic connection closing (and other boiler-plate code) is obviously a hard requirement to be handled by the fwk.
  • Pffffff. It's a trivial requirement which I can solve in my framework with two lines of code in a @Disposes method. Did you see any connection handling in the code above?
  • I mean, seriously guys. The Spring stuff is trivial and not even very elegant. I guess it's easier for me to see that, since I spent half my career thinking about data access and designing data access APIs. But even so...
  • I don't understand. You hate the ability to write typesafw SQL that much?
  • Gavin King
  • Methods with long argument lists are a code smell.
  • It's something Spring copied from Hibernate 1.x, back in the days before varargs
  • It's something we removed in Hibernate2 and JPA.
  • there are a bunch of people
  • who don't want to use JPA.
  • They don't understand, or see the value of, using managed objects to represent their persistent data.
  • Um. Why? Why would that be a bad thing? I imagine that any app with 1000 queries has tens of thousands of classes already. What's the problem? Why is defining a class worse than writing a method?
  • Are you working from some totally bizarre metric where you measure code quality by number of classes?
