12 Tips On JPA Domain Modelling - With Existing Database - Thinking In Structs Not Obje... - 0 views

  • think in structs. Try to as frictionless as possible export/generate the JPA-entities from the existing database
  • Implement a very thin facade / transaction boundary
  • @Stateless Bean (EJB 3)

  • If the JPA entities still do not look right, try to apply some JPA tricks like mapping a JPA-entity to several tables, or even map JPA-entities to DB-views, to improve the situation
  • Rename the classes into some more meaningful. The attribute, class names are in general everything but not fluent

How To Deal With Interfaces In Java EE 6 (or no more Impl) : Adam Bien's Weblog - 0 views

  • How To Deal With Interfaces In Java EE 6 (or no more Impl)
  • In Java EE 6 interfaces became absolutely optional. Neither in EJB 3.1, nor CDI / JSR-330 you need interfaces. You can inject classes directly. They will be still proxied, so all aspects like persistence, transactions, interceptors, decorators are still available. So you are no more forced to implement interfaces by the container
  • used for: Strategy Pattern: there are already several implementations of an algorithm or concept Layering: there is a clear need to hide e.g. an ugly implementation of a legacy framework API (not very common): you have to expose a API, which gets implemented by SPI (e.g. JDBC)
  • ...4 more annotations...
  • If you introduce interfaces intentionally - and not as a general rule, you will considerably reduce the number of files. Your code becomes easier to understand and so maintain
  • Even for decoupling purposes, interfaces are no more needed
  • "Contract First", "Coding To Interfaces" or "Decoupling"
  • is not a reason to introduce an interface for everything

Why Service Isn't A ServiceFacade, But ServiceFacade Is Sometimes A Service... : Adam B... - 0 views

  • boundary, which main responsibilities are:Providing coarser granularityEnsuring consistencyProviding a defined entry point which can be easily decorated with aspects / interceptorsExposure of components (what components are we will cover later) functionality to remote clients via IIOP, REST, SOAP, JMS, Hessian etc...
  • ServiceFacade - the facade to Services. The Services just rely on a certain amount of cross cutting aspects and concentrate on the realization of business logic
  • only invokes Services in consistent way, mostly using transactions
  • ...2 more annotations...
  • Services can remain independent
  • ServiceFacade combines them

Chapter 3. Project Setup - 0 views

  • The configuration of a GraniteDS project will generally involve the following steps : Add the GraniteDS jars to the WEB-INF/lib folder of the WAR file or the lib folder of the EAR file Add the GraniteDS listener, servlets and filters in the standard WEB-INF/web.xml configuration file Define the internal configuration of GraniteDS in the WEB-INF/granite/granite-config.xml file Define the application configuration of GraniteDS (remoting destinations, messaging topics...) in the WEB-INF/flex/services-config.xml
  • You will always need granite.jar
  • jar for your JPA provider (granite-hibernate.jar for Hibernate)
  • ...11 more annotations...
  • granite-beanvalidation.jar if you want to benefit from the integration with the Bean Validation API
  • configuration file declares 3 differents things
  • Channel endpoint
  • Service factories
  • Service/destinations
  • destinations using this factory will route incoming remote calls to EJB 3

7. Tide Framework - Confluence - 0 views

  • GDS/Tide project represents the Data Services part of GDS
  • comparable to LiveCycle Data Services, which is neither open source nor free, as it provides similar features such as client container of managed entities, data paging, and integration with server components, but it is based on completely different principles:
  • strongly typed Hibernate/JPA detached objects
  • ...5 more annotations...
  • All managed entity instances are unique in a Tide context
  • Tide keeps the classic three layers web architecture, when LCDS removes the service layer, and is some kind of remote JPA provider for Flex applications
  • Tide approach is to minimize the amount of code needed to make things work between the client and the server
  • principles are very similar to the ones of JBoss Seam, which is the main reason why the first integration of Tide has been done with this framework. Integrations with Spring, EJB 3 and CDI are also available
  • need to compile your MXML/AS sources with the granite-essentials.swc and granite.swc libraries

Article Series: Migrating Spring Applications to Java EE 6 - Part 1 | How to JBoss - 1 views

  • In fact people still love those books without realizing that the world has changed dramatically ever since
  • The reality check here is to wonder whether the rhetorics set forth by Rod Johnson in his 2003/2004 books are still actual today
  • So if you still care about those books, the best way to show your appreciation is probably to use them as your monitor stand
  • ...21 more annotations...
  • The discussion whether or not to use Spring vs. Java EE for new enterprise Java applications is a no-brainer
  • Why migrate?
  • since then fallen a prey to the hungry minds of Venture Capitalists and finally into the hands of a virtualization company called VMware
  • While the different companies and individuals behind the Spring framework have been doing some work in the JCP their voting behavior on important JSRs is peculiar to say the least
  • outdated ORM solution like JDBC templates
  • some developers completely stopped looking at new developments in the Java EE space and might have lost track of the current state of technology
  • size of the deployment archive
  • fairly standard Java EE 6 application will take up about 100 kilobytes
  • comparable Spring application weighs in at a whopping 30 Megabytes!
  • Lightweight
  • Firing up the latest JBoss AS 7 Application Server from scratch and deploying a full blown Java EE 6 application into the server takes somewhere between two and five seconds on a standard machine. This is in the same league as a Tomcat / Spring combo
  • Dependency injection
  • Java EE 6, the Context and Dependency Injection (CDI) specification was introduced to the Java platform, which has a very powerful contextual DI model adding extensibility of injectable enterprise services
  • Aspect Oriented Programming
  • “AOP Light” and this is exactly what Java EE Interceptors do
  • common pitfall when taking AOP too far is that your code might end up all asymmetric and unreadable. This is due to the fact that the aspect and its implementation are not in the same place. Determining what a piece of code will do at runtime at a glance will be really hard
