Our Agenda
• Overview of the new features
• Example application
• Dig into the code
Damn it, we need a new main
theme!
S Originally: PaaS (Cloud and multi-tenancy)
S No Cloud
S No Multi-tenancy
S But Productivity and HTML5
S Due date: Q2 2013
JSF 2.2
S renders HTML5
S <h:inputText value="#{bean.value}" >
<f:passThroughAttribute name="placeholder"
value="Enter text" />
</h:inputText>
S CDI ViewScope / Managed Beans deprecated
S Faces Flow
How to use the new features: http://www.marcusschiesser.de/2013/01/how-to-usejsf-2-2-with-jboss-7-1
CDI 1.1, EJB 3.2 & JPA 2.1
S @Transactional-Annotation
S But: Still no annotations for EJB Security
S CDI: Priority ordering of Interceptors and Decorators
S JPA: Stored Procedures and DB-Functions in JPQL
Method level validation
S Part of Bean Validation 1.1
@NotNull
public 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
S Java API for JSON Processing (JSR 353)
S Batch Applications (JSR 352)
Things we‘ll cover
S Java API for WebSockets (JSR 356)
S Bidirectional communication
S Directly over TCP
S No HTTP, only for Handshake via HTTP Upgrade
S JAX-RS 2.0
S 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.
