Java, JEE, OAS and WebLogic Server
Oracle Java and the application server
That depends on who you ask. Some people primarily will have taken goodies from the exhibition floors with them while other may have focused on less tangible goods and gone for inspiration and vision. After the heyday (2006/2007), some waning years and the robust recovery (2011) after an initially tentative turn around (2010) this year seems to have been one of consolidation and careful further evolution. Some choices have been made – not all of them popular but most apparently sensible and reliable because backed by commercial sense.
Session at JavaOne come in various shapes. Some are visionary, high level and future oriented. Others are detailed and discuss practical, sometimes very fine grained topics. One of the sessions I attended was somewhere in between: future oriented yet pretty concrete at the same time. It was probably my favorite session at JavaOne this year: What’s new in Servlet3.1: An Overview by Shing Wai Cha and Rajiv Mordani. The passion of the presenters – their enthusiasm to explain the current development of the Servlet API and their ability to demonstrate some rather tough concepts were pivotal. Many presenters can take their style as an example they can learn from.
The Servlet 3.1 API is part of the JEE 7 edition- that is scheduled for complete release in April 2013. The Servlet Specification is largely complete, although some elements are still under discussion as became clear during this talk. The probably most important new requirement in Servlet 3.1 is the ability to do Web Socket interaction. Web Sockets is a relatively new communication protocol that runs over TCP/IP and goes beyond HTTP in several respects. Web Sockets support bi-directional interactions (open channels through More >
The show is over, the visitors are on their way home. The process of digesting the announcements, roadmaps and rumors – confirmed or not – can proceed in full swing. What has become of last year’s plans, what are this year’s plans (for next year and beyond) and what has materialized in terms of Oracle’s product portfolio. For everyone, the answers to these questions and the conclusions will be somewhat different – depending on focus, expectations and requirements. However, some conclusions will be shared by most who attended Oracle Open World 2012.
Without a doubt, some of the important themes were and will be: cloud – and at respectable distance – the next generation of database technology (12c) and of engineered systems (Exa… X3-v2), of mobile availability of both standard applications (Fusion Applications and other Oracle Applications products) and custom Portals and applications (through ADF Mobile on iOS and Android)Facts and Opinions
The Facts may seem the easy part – since these are more or less objective – but as soon as interpretation and clarification enter the fray , the absoluteness of the facts is not assured. For example around availability: is the Oracle Cloud More >
While the double entendre of ‘SUNday’ no longer exists, this first day is still an important day. To set the stage, manage expectations, build on the atmosphere and layout the roadmap (starting that sometimes not even subtle massaging of the minds). The keynote sessions are the key events that define scope and themes for the conference.
Java is very much on the move again. After the virtual stand still just before and for a while after Oracle took over (from) Sun, last year saw a dramatic increase in the Java movement. This year that thread continues. Not with many spectacular announcement, but with a solid pursuit of earlier roadmaps and an apparently good collaboration between vendors in the Java space. The one big elephant in the room – that is actually not in the room at JavaOne – is Google. Otherwise for example, Oracle staff happily shared the stage for this keynote session with IBM.
This year’s overall slogan for JavaOne is: Make the future Java.
It is very much an invitation from Oracle to help bring the Java platform forward. In many ways: ideas, feedback, testing, propagating, creating code, joining JSR committees etc. Oracle and other vendors More >
Performance of Enterprise Java Applications is a requirement and usually a challenge. Business requirements on systems can be stiff, successful systems can easily be overloaded and complex application architectures can add a burden too. Improving performance by tuning the application after it has been built seldomly renders huge improvements. By taking a step back – or even two – and regarding the application and the performance from a distance, it becomes possible to really design and architect for performance according to the ISYITF-method: it is staring you in the face. Order of magnitude improvements are attainable through logical reasoning and careful application of multi-tier architecture principles and JEE platform facilities.
This is the abstract for the session Thinking Through Java Enterprise Performance that I will be presenting on Tuesday October 2nd at JavaOne 2012 (BOF 4712 4:30 PM – 5:15 PM – Parc 55 – Cyril Magnin I.
The show of the year is around the corner: on Sunday it will all start again, the Oracle Open World conference. Tens of thousands of developers, architects, administrators, project managers, decision makers and others involved with Oracle products one way or another are gathering in and around San Francisco. AMIS will attend with an 8 person team. We will present, network, publish and investigate. As much as we bring our knowledge and experience to the conference, we also want to find out many things. A quick list of some of the questions that are on the top of my head to get answered during thus year’s conference:Cloud
After last year’s announcements, we have not really seen any concrete cloud instances from Oracle. I hope to learn during this conference where exactly we stand and are headed with the Oracle Cloud – both the Application and the Platform Services. My focus will be on the latter in particular: what is the functionality and non-functionality offered by the various services – from Database Service to Web Services (PHP, Ruby and Python support) and Oracle Cloud Developer Services Hudson (for continuous integration, Git and GitHub for source control, wiki and tasks for More >
