Java EE Squad: March 2014

http://javaeesquad.blogspot.com/2014_03_01_archive.html

Tuesday, 4 March 2014. With the Octopus framework, you have a permission based security framework for Java EE which is highly customisable, CDI integrated and focussed on type-safety. You can protect URL’s, JSF components, CDI methods and EJB invocations with one and the same permission check code. It is licensed under the Apache License V2 and is sponsored by C4J. The Java EE ecosystem has his own security mechanism but it is role based. And this way of working has some major disadvantages. So I took th...

Terugblik op mijn StartupBus Europe 2015 ervaring. September 7, 2015. Februari 21, 2016. Inschrijven op de Dailybits lijst. Wie mij wat volgt op social media zal het ondertussen al wel door hebben dat ik mee op die bus zat (sorry voor het gespam). Mijn terugblik op de eerste echte Belgische bus in deze startupcompetitie en bijhorende avontuur. Ik hoop dat mijn verhalen velen andere mogen overtuigen om zich voor volgende jaar te gaan inschrijven. StartupBus meer dan gewoon een schoolreisje. Dat ik daarna ...

Java EE Squad: Auditing with JPA EntityListener

http://javaeesquad.blogspot.com/2015/02/auditing-with-jpa-entitylistener.html

Monday, 2 February 2015. Auditing with JPA EntityListener. A lot of the projects need some kind of audit trail. They want to know who and when the last time a record was changed. Or recently we got a question how you could keep record of who read some data from the database. Most of the time, there exists a database solution to these answers, but in other cases, it is easier to achieve with the JPA implementation. Keep record of reads. GenericEntity entity) }. Is an abstract class (see further on why it...

Java EE Squad: November 2014

http://javaeesquad.blogspot.com/2014_11_01_archive.html

Wednesday, 26 November 2014. Application module configuration with CDI 1.1. This text will tell you how you can use CDI itself to configure some portable extension of CDI you write yourself. So first a little bit of introduction what a portable extension is and why you should use it. When using CDI in your application, almost all the time you can just use what is available, like @Inject, @Named, the scopes and events to name the most important ones. An example of this can be. So far the introduction, now...

Java EE Squad: CDI event when transaction is finished

http://javaeesquad.blogspot.com/2015/06/cdi-event-when-transaction-is-finished.html

Monday, 29 June 2015. CDI event when transaction is finished. CDI events are a very handy way of loosely coupling event driven code. At some point in your code you raise the event, and in some other area, you execute some functionality when this event occurs. And there is no relation or code dependency between the 2 areas except the CDI event payload class. DataUpdatedEvent dataUpdatedEvent) { / React on event. A scenario that I used recently was to have some Cache. By default, as already mentioned, it i...

Java EE Squad: August 2014

http://javaeesquad.blogspot.com/2014_08_01_archive.html

Sunday, 3 August 2014. Concurrency aspects of a Singleton EJB bean. In the previous blog text, I demonstrated some aspects of a Stateless EJB bean. It is guaranteed that each client receives his copy of the bean and that there is no concurrent access. But it is possible, and here there where differences between the application servers, that the same bean instance is reused in different calls. With the same set of examples, I’ll explain them to you. Click 1 - value = 1. Click 2 - value = 2. Since we now h...

Java EE Squad: CDI for Java SE already standardised with DeltaSpike

http://javaeesquad.blogspot.com/2014/12/cdi-for-java-se-already-standardised.html

Friday, 19 December 2014. CDI for Java SE already standardised with DeltaSpike. One of the things which are scheduled for the upcoming CDI 2.0 release, is the standardisation of the usage in a Java SE environment. The Context part of CDI, the different scopes like RequestScoped or ApplicationScoped, isn’t the most useful thing in the Java SE environment. But having a dependency injection and event mechanism on the other hand is very handy. DeltaSpike Container Control module. Other things you need are.
