Our Agenda
• Overview of the new features• Example application• Dig into the code
Damn it, we need a new main theme!
Originally: PaaS (Cloud and multi-tenancy)
No Cloud
No Multi-tenancy
But Productivity and HTML5
Due date: Q2 2013
JSF 2.2
renders HTML5
<h:inputText value="#{bean.value}" > <f:passThroughAttribute name="placeholder" value="Enter text" /> </h:inputText>
CDI ViewScope / Managed Beans deprecated
Faces Flow
How to use the new features: http://www.marcusschiesser.de/2013/01/how-to-use-jsf-2-2-with-jboss-7-1
CDI 1.1, EJB 3.2 & JPA 2.1
@Transactional-Annotation
But: Still no annotations for EJB Security
CDI: Priority ordering of Interceptors and Decorators
JPA: Stored Procedures and DB-Functions in JPQL
Method level validation
Part of Bean Validation 1.1
@NotNullpublic MyObject createMyObject(
@Size(min=5, max=40) String name, @DecimalMin(value="1.00") Double
value, @Pattern(regexp="\\d{8}") String code)
{...
JMS 2.0
@Inject@JMSConnectionFactory("jms/connectionFactory")private JMSContext context;
@Resource(mappedName = "jms/inboundQueue")private Queue inboundQueue;
public void sendMessage(String payload) {context.send(inboundQueue, payload);
}
Some new APIs
Java API for JSON Processing (JSR 353)
Batch Applications (JSR 352)
Things we‘ll cover
Java API for WebSockets (JSR 356) Bidirectional communication Directly over TCP No HTTP, only for Handshake via HTTP Upgrade
JAX-RS 2.0 finally a REST-Client
Sample app „MyAktion“
Our sample application allows organizers of nonprofit campaigns to create online fundraising forms for their projects. The organizer can embed these forms into their own website. This allows the organizer to raise money for his campaign. Each organizer can create forms for multiple campaigns.The application takes care of the generation of the forms and the management of the campaigns and donations.
