Bytecode Verification, the Hero That Java Needs [JavaOne 2016 CON1500]David Buck
Often the true mark of a successful technology is when something works so well that those who benefit the most from it are not even aware of its existence. Java’s bytecode verification undoubtedly falls into this category, but it is as vital as ever to keeping Java secure and safe. This session takes a deep dive into the safeguards that bytecode verification provides for us and shows how it continues to protect us from not only malicious code but also our own mistakes.
This session will explore how Java development has been brought into the open over the past decade and where it is headed in the future. Several Java developer efforts have brought open source development processes and new levels of transparency and participation into their communities. This year theJava Community Process (JCP) program celebrates twenty years of Java standards development. Since the initiation of efforts to expand the developer participation in the Java community, Java standards development is more open that it ever has been. Learn how to take part in the Java developer community, upcoming changes to the Java platform, and how you can contribute. You can participate as an individual, corporation, or nonprofit such as a Java user group (JUG). This session answers your questions about why and how to participate in the evolution of the Java platform - how you can participate in contributing to the future of Java.
Harnessing the Power of Optimizer HintsMaria Colgan
The goal of the Oracle Optimizer is to examine all possible execution plans for a SQL statement and to pick the one with the lowest cost, which should be the most efficient. From time to time, it may become necessary to influence the plan the Optimizer chooses. The most powerful way to alter the plan chosen is via Optimizer hints. But knowing when and how to use Optimizer hints correctly is somewhat of a dark art. This session explains in detail how Optimizer hints are interpreted, when they should be used, and why they sometimes appear to be ignored.

Towards the end of the session we will discuss what's coming in WebLogic 12.2.1 this year including full support for Java EE 7, multi-tenancy and more.
Presentation at FOSS ASIA 2015 in Singapore, on March 15th 2015. This presentation explains benefit of "SQL and NoSQL" hybrid data management solution MySQL Cluster. MySQL Cluster is designed as high available and high scalable database cluster. In the same time MySQL Cluster can work as ACID compliant transactional Key-Value Datastore aka KVS #FOSSASIA
With a strong focus on annotations, minimalist configuration, simple deployment, intelligent defaults and Java centric type-safety, Java EE is one of the most productive full-stack development platforms around today. This very code centric workshop is a quick tour of the Java EE platform as it stands today. If you haven't seen Java EE for a while and want to catch up, this session is definitely for you.
We will start with the basic principals of what Java EE is and what it is not, overview the platform at a high level and then dive into each key API like JSF, CDI, EJB 3, JPA, JAX-RS, WebSocket and JMS using examples and demos. This is your chance to look at Java EE 7 in the context of a realistic application named Cargo Tracker, available with an MIT license at http://cargotracker.java.net.
We will also briefly take a look at the emerging horizons of Java EE 8.

How is Java / JVM built ? Back then and now...Mani Sarkar
As some of you may already know, starting with Java 7, OpenJDK is the Reference Implementation (RI) to Java. This presentation walks you through just about that and throws light into many areas that are not common knowledge about this subject.
Having said we must move on with time, we used certain tools and methods to do our work in the past and now with improved technology we adapt with the shiny new tools and blend our work with it.
A modern web browser supports a surprising number of protocols designed for fast, efficient, and secure communication. Even though some goals of these protocols might overlap, their features are different enough to make them all worth our attention. This session focuses on HTTP/2, SSE, and WebSocket. It is based on experience gained during development of popular Jersey and Tyrus libraries. It explains all mentioned protocols and compares them, in both theory and practice, using java-based examples.

If you are inspired during practical and hands-on sessions during the three days at Devoxx UK 2015, have you thought about how you might pass on this knowledge and experience to others? If so, then we have just the right solution for you! Running a Hackday, either at your workplace or within your local community, can be very rewarding. Come along to this session and learn all about the art of running hack session from Richard Warburton, author of Java 8 Lambda and regular organiser of hackdays in the London Java Community.
You will be able to answer your own questions like: Why you should run a hackday ? What’s involved in running one ? Examples of successful hackdays Tips for being successful
Java EE 8 Overview (Sept 2015). A lot of work is already done by the Expert Groups so lets have a brief look for what we can expect in the some areas.
- Servlet 4 will embrace the new HTTP/2 protocol.
- JSON-B will bring the same high level features of JAXB to the JSON data format.
- Server-Sent Events(SSE) is the WebSocket variant where you only send data from the server to the client.
- MVC will be the Action based MVC complement of the Component based MVC of JSF.
- Some major restructuring of CDI so that we can use it standardised in Java SE to mention one thing.
The Java EE security API will be covered in more detail. Security related things became old and dusty and needs to move away from proprietary configuration to be able to make the transition to the cloud. An introduction to JSR 375 is given, which promotes self-contained application portability across Java EE servers, and promotes the use of modern programming concepts such as Expression Language, and CDI. It will holistically attempt to simplify, standardize, and modernize the Security API across the platform in areas identified by the community.
Real world batch implementations and frameworks.
These slides explores various ways in which batch processing can implemented with Java EE and other frameworks. It includes pro and cons of batch implementations with JCL, prepared statements, CDI, JSR 352 and embedded EJB containers. It helps to understand when to use JSR 352 and when not to, the benefits of using an embedded EJB container for batch processing, and the best practices to follow when designing batch processes.
Dynamically assembled REST Microservices using JAX-RS and... Microservices? -...mfrancis
OSGi Community Event 2016 Presentation by Neil Bartlett (Paremus)
REST microservices are a powerful tool for composing large-scale systems, and the standalone nature of a microservice helps to avoid it becoming part of a “big ball of mud” application. Given the power and success of microservices as inter-process modules, why stop there? OSGi has offered in-process microservices for nearly two decades, and uses them to great effect in modular applications.
The new OSGi JAX-RS whiteboard service allows dynamic OSGi services to be automatically exported as JAX-RS Resources, Filters or Applications. These “Microservice modules” can be easily shared or moved between frameworks, allowing you to benefit from a microservice structure that goes all the way down.
Background
Over the last decade there has been a significant shift in the way that many computer programs are written. The focus has changed from building larger, more monolithic applications that provide a single high-level function, to composing these high-level behaviours from groups of smaller, distributed services. This is generally known as a “microservice” architecture, indicating that the services are smaller and lighter weight than typical web services.
The standard for REST microservices in Java is known as JAX-RS. JAX-RS provides a simple annotation-based model in which POJOs can have their methods mapped to RESTful service invocations. There is automatic mapping of HTTP parameters, and of the HTTP response, based on the annotations, and the incoming HTTP Headers. JAX-RS also includes support for grouping these POJOs into a single Application artifact. This allows the POJOs to interact with one another, as well as to share configuration and runtime state. When used in JAX-RS these POJOs are known as JAX-RS resources.
Ideal JAX-RS resources are stateless, and are usually instantiated by the container. JAX-RS resources share many features with OSGi services, in that they provide a way for machines (or processes within a machine) to interact with one another through a defined contract. This synergy between JAX-RS resources and OSGi services is the driver for the OSGi JAX-RS whiteboard service, allowing OSGi services to be transparently exposed using JAX-RS.

Talk on Java Community Process updates and progress towards more openness and transparency. Also includes information on Platform updates and how to participate in activities. This talk is from various events in EMEA in the Fall of 2018.
In the modern world, where apps consist of microservices and are deployed in a cloud, developers are facing many issues related to apps config. How to deploy an app in different environments without cracking its package. How to apply configuration for deployed instances of an app without redeployment. How an app can be notified if some configuration properties changes. This session introduces a standardization effort tasked with solving these problems by defining a Java EE config service. Such a service is aimed at the cloud and provides the ability to create one or more configurations that are independent of and decoupled from apps using them. The session describes how such a service fits into the Java EE family and integrates with other Java EE frameworks.
Join the Java Evolution GIDS Bangalore & PuneHeather VanCura
The Java Community Process (JCP) is key to the evolution of Java technology. This session emphasizes the value of transparency and participation in the JCP program, through both Java User Groups (JUGs), and through the Adopt-a-JSR program, the grass roots, community led and developed program to empower Java developers around the world to make a contribution to Java technology. Find out how to become an active participant in advancing the Java platform - JSRs for Java Enterprise Edition (Java EE) 8 and Java Standard Edition (Java SE) 9 are being developed now. This session discusses the transparency that enables participation in the JCP program and how to get involved through the Adopt-a-JSR program. You will also hear about some upcoming changes to the Java Specification Request (JSR) process itself through the JCP.next effort, and learn how you can get involved. Come with your questions/suggestions, and leave with the motivation and information you need in order to become an active participant in advancing the Java platform now and in the future.

Helidon Nima - Loom based microserfice framework.pptxDmitry Kornilov
For quite a long time we were forced to make a choice - performance vs. simplicity. Either use a complicated and performant reactive code, or use simple, yet limited blocking approach.Thanks to project Loom in JDK, the paradigm can shift once more even for applications that require high concurrency. I will introduce Helidon Nima - new microservices framework which is built on top of a server designed for Loom with fully synchronous routing that can block as needed, yet still provide high performance under heavy concurrent load. I'll also talk about challenges, benefits and impact on application development in such an environment.
Building Cloud-Native Applications with HelidonDmitry Kornilov
Slides for my and Johan Palmer presentation on Oracle Open World 2019.
Abstract:
Project Helidon is an open-source framework that supports customers developing Java-based microservices applications. Helidon SE is designed to be simple to use, lightweight, and fast. In addition, Helidon also implements MicroProfile, a baseline platform definition that optimizes Java EE for microservices architectures, and delivers application portability across multiple runtimes. Come to this session to learn what Helidon is, gain an understanding of the strategy and roadmap, and uncover how you might benefit from using Helidon in your business.
Slides from my and Tomas Langer session at CodeOne 2019.
Abstract:
Although Helidon SE provides reactive nonblocking APIs to build microservices, most database drivers are still blocking. Only a few vendors provide reactive drivers to their databases. To help mitigate this issue, a reactive persistence layer has been created in Helidon SE. This persistence layer, known as Helidon DB, supports SQL and NoSQL databases and is compatible with R2DBC, ADBA, the MongoDB reactive driver, and standard JDBC. With Helidon DB, there is no need to worry that a database driver will block your thread. This session covers the basic concepts of Helidon DB and demonstrates how it works with different kinds of databases on a simple sample application.
