This document discusses building WebSocket applications in Java using JSR 356. It begins with an introduction to WebSockets and their advantages over traditional HTTP for interactive web applications. It then covers the JSR 356 specification for a Java API for WebSocket, including annotated and programmatic endpoints. The document provides examples of basic "hello world" clients and servers. It also discusses more advanced topics like custom payloads, URI template matching, security, and relationships with dependencies and Servlet APIs.
HTTP/2 comes to Java. What Servlet 4.0 means to you. DevNexus 2015Edward Burns
It’s hard to overstate how much has changed in the world since HTTP 1.1 went final in June of 1999. There were no smartphones, Google had not yet IPO’d, Java Swing was less than a year old… you get the idea. Yet for all that change, HTTP remains at version 1.1.
Change is finally coming. HTTP 2.0 should be complete by 2015, and with that comes the need for a new version of Servlet. It will embrace HTTP 2.0 and expose its key features to Java EE 8 applications. This session gives a peek into the progress of the Servlet spec and shares some ideas about how developers can take advantage of this exciting
update to the world’s most successful application protocol on the world’s most popular programming language.
Reactive Java EE - Let Me Count the Ways!Reza Rahman
As our industry matures there are pockets of increased demand for high-throughput, low-latency systems heavily utilizing event-driven programming and asynchronous processing. This trend is gradually converging on the somewhat well established but so-far not well understood term "Reactive".
This session explores how vanilla Java SE and Java EE aligns with this movement via features and APIs like JMS, MDB, EJB @Asynchronous, JAX-RS/Servlet/WebSocket async, CDI events, Java EE concurrency utilities and so on. We will also see how these robust facilities can be made digestible even in the most complex cases for mere mortal developers through Java SE 8 Lambdas and Completable Futures.

WebLogic 12.1.3 was released late last year. It brings a large set of changes including support for some key new Java EE 7 APIs such as WebSocket, JAX-RS 2, JSON-P and JPA 2.1, support for Java SE 8, WebSocket fallback support, support for Server-Sent Events (SSE), improved Maven support, enhanced REST administration support, Oracle Database 12c driver support and much, much more. In this session we will take a detailed tour of these features. In addition we will also cover updated WebLogic support in the Oracle Cloud, the new Oracle public Maven repository, using WebLogic with Arquillian for testing and well as official Docker support for WebLogic.
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.
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.
Java EE 7 from an HTML5 Perspective, JavaLand 2015Edward Burns

We use the Cargo Tracker sample Java EE 7 application as the vehicle for this explanation. Diving into the code, we examine the parts of the Java EE 7 family of technologies, and the HTML5 techniques used in the application.
Many enterprise systems build at 2000 - 2010 uses J2EE old specifications with Struts web framework. But nowadays J2EE improved as Java EE, with standard web framework JSF 2. With this slides you can learn how to migrate old-styled J2EE + Struts systems to sophisticated Java EE with JSF 2 specification. This slides was used in Java Day Tokyo 2014 C4 window, presented by the author. And some slides is specialized for Japanese enterprise systems, but the theme is very standard and for almost all J2EE users in the world.
This presentation introduces the new Java EE 8 Security API JSR 375. Originally presented at Devoxx France 2015, the slides present the motivation behind the new JSR, some history, the expert group, and a summary of ideas.
The slides were created after the expert group had been meeting for about a month, so the ideas are raw and undeveloped. However, the ideas in the slides do indicate the general direction the JSR is headed, with respect to modernizing, simplifying, and standardizing the Java EE Security API.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
