[pt_BR] Encontro SouJava na Oracle do Brasil

No dia 21 de Fevereiro estreamos o novo escritório da Oracle abrindo as portas para o grupo de usuários do SouJava. Com a presença do Bruno Souza, Ricardo Ferreira, Edgar Silva, Vinicius Senger, Mauricio Leal e muitos outros, tivemos a participação ao todo de 26 pessoas.

Durante a reunião, apresentei As Novidades do JMS 2.0, parte importante do Java EE 7 e que teve votação do Public Review no dia 19/02. O SouJava votou a favor, não só pela qualidade mas também pela transparência da especificação.

A outra apresentação foi do Ricardo Ferreira, falando sobre Processamento de Dados em Memória usando Elastic Data Grid (In-Memory Computing), que demonstrou a importância do uso de cache distribuído em arquiteturas altamente escaláveis, com o Oracle Coherence.

No final, os participantes conheceram o novo escritório da Oracle e ainda foram muito bem recebidos com muita pizza.

 Obrigado a todos que participaram!

Using Coherence API to get POF bytes

Someone raised the question on how to use the Coherence API to get the bytes of an object in POF (Portable Object Format) programatically. So I came up with this small code that shows the very cool API simple usage :-)

   SimplePofContext spc = new SimplePofContext();
   spc.registerUserType(0, User.class, new UserSerializer()); 
   // consider UserSerializer as an implementation of PofSerializer
            
   User u = new User();
   u.setId(21);
   u.setName("Some Name");
   u.setEmail("some.name@domain.com");
            
   ByteArrayOutputStream baos = new ByteArrayOutputStream();
   DataOutput dataOutput = new DataOutputStream(baos);
   BufferOutput bufferOutput = new WrapperBufferOutput(dataOutput);
   spc.serialize(bufferOutput, u);
            
   byte[] byteArray = baos.toByteArray();
   System.out.println(Arrays.toString(byteArray));

 Easy, isn't?

JavaOne 2012: Camel, Twitter, Coherence, Wicket and GlassFish

Before joining Oracle as Product Manager for WebLogic and GlassFish for Latin America, at the beggining of this year I proposed two talks to JavaOne USA that I had been presenting in Brazil for quite a while. One of them I presented last year at ApacheCon in Vancouver, Canada as well in JavaOne Brazil. In June I got the news that they were accepted as Alternate Sessions. Surprisingly enough, few weeks later and at the same time I joined Oracle, I received the news that they were officially accepted and put on schedule.

Tomorrow I'll be flying to San Francisco, to my first JavaOne in the United States, and I wanted to share with you what I'm going to present there.
My two sessions are these ones:

  1. Wed, 10/03, 4:30pm - CON2989 Leverage Enterprise Integration Patterns with Apache Camel and Twitter

    On this one, you will be introducted to the Apache Camel framework that I had been talking about in Brazil at conferences, before joining Oracle, and to a component I contributed to integrate with Twitter. Also, you will have a preview of a new component I've been working on to integrate Camel with the Oracle Coherence distributed cache.

  2. Thu, 10/04, 3:30pm - CON3395 How Scala, Wicket, and Java EE Can Improve Web Development

    This one I've been working on for quite a while. It was based on an idea to have an architecture that could be as agile as frameworks and technologies such as Ruby on Rails, PHP or Python, for rapid web development. You will be introduced to the Apache Wicket framework, another Apache project I enjoy working with and gave lots of talks at Brazilian conferences, including JavaOne Brazil, JustJava, QCon SP, and The Developers Conference. You will also be introduced to the Scala language and how to create nice DSLs to boost productiveness. And last but not least, the Java EE 6 platform, that offers an awesome improvement from previous versions with its CDI, JPA, EJB3 and JAX-RS features for web development.

Other events I will be participating during my stay in SF:

  1. Geeks Bike Ride
  2. GlassFish Community Event
  3. GlassFish and Friends Party 

 

If you have any other event to suggest, please do suggest! It's my first JavaOne and I'm really looking forward to enjoying everything.

See you guys in a few days!!
