Make the Future Java

Most projects stop applying modularity principles at the granularity of classes. This is unscalable: at some size of code base it extracts a significant tax on development dollars as the team starts to drown in an ever-expanding ocean of classes. The Java package structure, when used to organize files as if they were plain office documents, does not provide meaningful abstractions that help developers manage the vast number of inter-file dependencies. This session provides concrete strategies for constructing a hierarchical, levelized, modular package structure for an existing code base, with minimal impact on the working code. Illustrative manipulations to Levelized Structure Maps (LSMs) in Restructure101 show pattern-action-result scenarios.

This session focuses on the internet of things, based on real Java implementation. You will see more than 10 demos using different devices, concepts, user-interfaces, and Java technologies, including Java SE, Java ME, Java embedded, JavaFX, and Java EE with GlassFish as an internet-of-things gateway.

Learn what every programmer should know about secure programming in Java. This session focuses on programming issues as the source of systems flaws. It touches on several areas, including language specification and features, inadequate programing and testing, and some human factors based on the psychology of programming applied to secure programming. The session uses de facto standard references such as OWASP Top 10, Sans Top 25, CERT Secure Coding, and CWE. Finally, the session offers tips for avoiding risky features and for improving your secure-programming abilities, and it answers the questions: "Is Java language more (or less) secure than other languages, such as C# or C/C++?" and "What about dynamic languages and mobile application development?"

Programming is a journey. To achieve effective, clean, easy-to-read, and beautiful Java code, you have to practice programming every day. This session shares some lessons collected along 15 years of Java programming. It includes live code examples of how to write truly object-oriented code; when to make a type (and how to use it on JPA providers); how to properly use encapsulation and polymorphism in "ifless" programming; how to properly take advantage of the enum power; and how to use some very useful open source libraries such as Google Guava and Joda-Time to achieve clean Java code.

Regular expressions are the forgotten treasures in the Java ecosystem. They provide full support for advanced string searching, replacing, and validating in Java. However, regular expressions are not used as much as they deserve to be. In this session, Swedish JUG leader and Java Champion Mattias Karlsson and Pragmatic Bookshelf author Staffan Nöteberg show how you can benefit from regular expressions in Java and also how you can implement them in a disciplined, test-driven way. The session provides subject-matter background, Java live-coding, and ideas of the possibilities for using regular expressions in Java.

With Java SE 7 having been available for more than a year, it is time to start using it. A common question is, “Why should I update to Java SE 7? I don’t use any of the new language constructs.” This session aims to answer why it is beneficial to update your production environment to Java SE 7, even if you are not using invokedynamic, NIO.2, or any of Java SE 7’s other new features. There are plenty of reasons why you should consider moving up to Java SE 7.

The Java Community Process (JCP) plays a critical role in the evolution of Java. This session emphasizes the value of transparency and participation in the JCP, Java user groups (JUGs), and the Adopt a JSR program. You will also hear about some upcoming changes to the Java Specification Request (JSR) process through the JCP.next effort, and learn how you can get involved. Come with your questions, your suggestions, and your concerns, and leave with the motivation and information you need to become an active participant in advancing the Java platform.

There are many implementations of JavaScript, meant to run either on the JVM or standalone as native code. Both approaches have their respective pros and cons. The Oracle Nashorn JavaScript project is based on the former approach.This presentation goes through the performance work that has gone on in Oracle’s Nashorn JavaScript project to date in order to make JavaScript-to-bytecode generation for execution on the JVM feasible. It shows that the new invoke dynamic bytecode gets us part of the way there but may not quite be enough. What other tricks did the Nashorn project use? The presentation also discusses future directions for increased performance for dynamic languages on the JVM, covering proposed enhancements to both the JVM itself and to the bytecode compiler.

New releases of the Java SE and Java EE specifications provide many great features that can make you more productive and make your code more secure and powerful. But figuring out how to use these new features can sometimes be daunting. Why not let NetBeans help you figure it out? Come to this session and see how NetBeans can help you unlock the power of the Java EE 6 and Java SE 7 releases. You will also get a look at how NetBeans is planning to support upcoming releases of the Java platform.

The Java APIs competition is evolving with each new version. But the package java.util.concurrent thread, all are focused on controlling which thread performs which task. The problem is that when a task is too big, turn it into a single processor can be very time consuming. Since virtually all current machines have multiple processors, the new framework Fork / Join is included in Java 7 provide ways to take advantage of it. With it, we can break down each task into smaller pieces, distributing them among processors and put it all together into a final result. In this talk, we will demonstrate how to use the Fork / Join to export a large body of data from a CSV of sales for a JSON.

Do you want to learn details of the new NetBeans Project EASEL? If so, come to this session, which discusses current trends in HTML5, CSS3, and JavaScript application development, including responsive CSS layouts for multiformat displays from one application. It shows how Project EASEL enables developers to create and manage client-side HTML5/CSS3/JavaScript applications. Details covered include working with the JavaScript library manager; code completion for HTML5, JavaScript, and jQuery; CSS styling of dynamically generated content; browser integration for fine-tuning CSS; and JavaScript debugging. All of this from the same IDE in which you are also developing your Java-based RESTful Web services.

The world is not the same place it was when Java started. It’s 2012, and attackers are intensely motivated, sophisticated, and organized. Java security is a significant concern across all organizations as well as for individuals. Oracle takes the concern seriously and is working on it in several ways. Attend this session to learn about Oracle’s plans to harden Java.

Enterprise technology is moving to the cloud, and it’s bringing social with it. Social has proven value for brands and consumers, but enterprises have yet to fully leverage its business potential. As with the cloud, it’s clear that social is extending across the enterprise from consumer-facing experiences to employee collaboration, with all the underlying data that enables CRM enrichment and predictive personalization. But where does the enterprise developer get involved? This presentation shares Oracle’s vision for the social-enabled enterprise and highlights the role developers will play in the next phase of enterprise development.

In conventional systems, concurrent and distributed programming is complicated—a potential nightmare waiting to happen. That's where the actor model comes in. With the actor model, it is much simpler to develop highly concurrent applications, taking advantage of all the hardware available and, when necessary, making them distributed. That plus the ease of writing fault-tolerant systems makes the actor model an unbeatable solution. This session helps you understand the ideas and functioning of the actor model, with examples using the Akka framework.

In this session, get to know Oracle Developer Cloud Services, a hosted environment for your application development infrastructure, including version management, build services, tasks and defects tracking, wikis, document, storage and more.

Attend this session to understand which CDI features make it excel in comparison with other dependency-injection-based solutions and to learn how those features can be used to design flexible applications and frameworks that will stand the test of time. This presentation was delivered at JavaOne San Francisco 2012.

Are you sure your code and architecture are secure enough? If not, you're not alone. Many Java EE Web applications have security breaches that could be avoided easily by using simple programming techniques and Java EE application server configurations. This session explains the main security flaws and how you can protect your application from them by combining architecture decisions and the latest HTTP header flags and Web container configurations available. You will learn not only about common problems such as cross-site scripting and session hijacking but also about how to securely deal with user passwords and other issues that are frequently neglected by developers. This will be a live-hacking and fix session.

The amount of data available in the world today is exploding. Analyzing and processing large data sets, called big data, is a challenge, and Hadoop is becoming the standard tool for dealing with it. This session discusses big data and Hadoop concepts, including real-life examples and an architecture for integrating Hadoop, relational databases, NoSQL databases, and traditional BI tools. It also takes a deep dive into important related concepts such as MapReduce patterns, data ingress and egress with Hadoop APIs, Flume and Sqoop, automated mechanisms with Oozie, and data serialization with Thrift and Avro, using a social network integration as an example.

How do you protect your online sources of information and safely provide access to those who are willing to pay for them? OAuth is a specification that handles online access through Web servers, ensuring that the right people can get the right information. This session explains the basics of OAuth and demonstrates how to protect your data through an OAuth provider.

Today there is no de facto standard for REST resources specification, and companies often end up adopting very different strategies in their API design. This presentation discusses some alternatives regarding API design, including use of content types, versioning, search, paging, attributes, modeling resources, authentication, and authorization, and evaluates the potential impacts of each alternative on modeling, infrastructure, and performance. It also proposes a set of heuristics to assist in decision paths that can be followed, with implementation examples using Spring MVC, Jersey, and Groovy.

There's a lot of information out there about REST, so naturally a lot of that information is inaccurate, incomplete, confusing, and misleading. In this session, learn how to build pure REST Web services in Java (including details of JSR 339) in a practical way. See how HATEOAS can transform your Web services and how you can take advantage of an HTTP infrastructure to tune your real Java EE Web services, and benefit from lessons learned during a back-office development project in a large exchange bank.

The Java EE 7 platform, scheduled to release in the first half of 2013, has a changed scope and will now be focusing on productivity and HTML5. JAX-RS 2 adds a new client API to invoke the RESTful endpoints. Java Message Service (JMS) 2 is undergoing a complete overhaul to align with improvements in the Java language. Long-awaited batch-processing and caching APIs are also being added, along with a new API for building WebSocket-driven applications and a new API for parsing, generating, transforming, and querying JSON. JavaServer Faces (JSF) will add support for HTML5 forms. There are several additional improvements coming in this latest version of the platform, and some of the implementations are already integrated in GlassFish.

The purpose of this technical session is to elaborate on all the new features being introduced as part of this new major API revision.This session explores the new client API, concepts behind filters and interceptors API, and asynchronous processing support. Other new features it covers include data validation support and improved support for hypermedia and server-side content negotiation. The last part of the session also briefly outlines future plans and focus areas.

Jenkins is the most-adopted open source continuous integration server today, and beyond the automated build and test, it is a platform for launching all kinds of automation tasks. As the use of Jenkins grows inside an organization, people are automating complex activities that need to be choreographed—such as deploying an application, running a load test, cleaning up the environment, and then handing over the build to the operation team. Such orchestration of activities is a very useful building block for continuous delivery, a practice promoted in recent years. While making individual steps (such as test, deploy, and build) automated are relatively well understood, the same cannot be said about hooking these steps together efficiently. This session looks at various patterns and plug-ins that deal with this kind of choreography.

In modern development environments, it’s a “must” to include testing of Web applications as a standard part of the development lifecycle. JavaServer Faces (JSF) projects, though, can be particularly difficult to test with basic tools. We’ve seen a revolution with Arquillian that has made integration testing a breeze. Similarly, Selenium helps in UI testing automation. However, neither Arquillian nor Selenium can save the world alone. This session looks at some Arquillian extensions that bridge the gap between the worlds of JSF testing with Arquillian and Selenium. Additionally, it investigates how to take a client-side test to the server and back, verifying state at both ends.

Ten years ago, driven by demands for scalable architecture as a result of new internet-inspired business models and the SOA revolution, we saw the birth of the Java distributed caching market.
