8 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); }

9 Some new APIs  Java API for JSON Processing (JSR 353)  Batch Applications (JSR 352)

10 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

11 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.
