JSR-299 (CDI), Weld & the Future of Seam (JavaOne 2010)Dan Allen
Introduces JSR-299, the new Java standard for contextual lifecycle management, dependency injection (CDI) and event notification. Covers the core programming model, explains its relationship to EJB 3.1 and JSF 2.0, and clarifies how it unifies and enhances the Java EE platform as a whole (extending to JPA, JAX-RS and JMS). You are then introduced to Weld, the JSR-299 Reference Implementation, and its Servlet container and Java SE extensions. Finally, looks ahead at how a modularized Seam 3 ties into this new foundation as a set of portable CDI extensions.
Throwing complexity over the wall: Rapid development for enterprise Java (Jav...Dan Allen
For many, development of enterprise Java has long been an arduous undertaking. We're of the opinion that application programmers should be free to focus on their business logic only.
In this session, we'll cover:
• What makes us most productive?
• What tasks should we be programming; more importantly, what shouldn't we?
• What is a component model, and what does it buy us?
• How is this stuff usable in the real world?
We'll discuss how testing relates to the features of the Java EE 6 stack. By the end, we'll have introduced a pair of simple and powerful frameworks that render the testing of real enterprise components as natural as calling "add" on a CS101 Calculator.java.
Micro-services are the new black; everyone is using them. Alas, when your system is composed of many micro-services, testing becomes more challenging. The straight-forward approach for E2E testing no longer suffices and for integration tests it doesn't even exist. A better way to test in this kind of an environment would be to work with a test kit of the micro-service you are interacting with.
By the end of this talk, you will learn how to create a test-kit that covers your micro-service. Testing this way will grant you a much higher level of confidence, and will portray a more accurate picture of your assumptions vs. reality. Overall it will make any integration between micro-services easier, thus benefit your colleagues and make your company progress faster.

Devoxx UK 2013 Test-Driven Development with JavaEE 7, Arquillian and Embedded...Peter Pilgrim
In this session, we introduce the Java developer to the Arquillian framework, Gradle and the Enterprise container technologies in Java EE 7. As a lucrative bonus we will cover building EJB and Java EE 7 tests applications with Gradle, the latest and greatest build framework for the Java platform, which improves on Apache Maven. The Java EE specification full contains three different containers, namely the Web, the EJB and the CDI containers. All of them can be reached using the Arquillian Framework, and this means there is now one general testing framework, which developers should learn as part of their professional duties. The session will cover writing meaningful tests for CDI, EJB and JAX-RS. Along the way, we will introduce new features of EJB 3.2, CDI 1.1 and RESTful Services. GlassFish Embedded Container 4.0 will be demonstrated.
Harpreet Singh is the technical lead for GlassFish v2.1. GlassFish v2.1 is an open source application server that is the Java EE 5 reference implementation. It provides bug fixes and no regressions from previous versions, and new features like hooks for integration with Enterprise Manager. It has been extensively tested on various platforms and shows no performance regressions.
Batch Applications for Java Platform 1.0: Java EE 7 and GlassFishArun Gupta
The document discusses Java batch processing and Java EE 7's standardization of batch applications for Java. Key points include that batch processing is non-interactive, long-running data or computationally intensive tasks that can run sequentially or in parallel. The Java EE 7 specification includes standards for chunked processing using readers, processors and writers along with checkpointing and exception handling.

Alban Diquet, Data Theorem
Thomas Sileo, Data Theorem
Over the last two years, we've received and analyzed more than three million SSL validation failure reports from more than a thousand of iOS and Android apps available on the Stores, and used all around the world. From mobile banking to music apps, each report was triggered because an unknown or unexpected certificate was being served to the app, preventing it from establishing a secure connection to its server via SSL/TLS.
We've analyzed each of these reports to understand what caused the SSL connection to fail, and then grouped similar failures into various classes of SSL incidents. Throughout this presentation, we will describe the analysis we've made and present our findings.
First, we will provide a high-level overview of where, how, and why SSL incidents are occurring across the world for iOS and Android users, and describe the various classes of incidents we've detected. Some of these types of incidents, such as corporate devices performing traffic inspection, are well-known and understood, although we will provide new insights into how widespread they are.
Then, we will take a closer look at a few notable incidents we detected, which have been caused by unexpected, or even suspicious actors. We will describe our investigations and what we found.
Lastly, we will provide real-world solutions on how to protect apps against traffic interception and attacks, as a mobile developer.

Jenkins Online Meetup - Automated SLI based Build Validation with KeptnAndreas Grabner
This document discusses automating SLI/SLO based build validation with Keptn and Jenkins. It begins by outlining the challenges of lengthy manual approval processes for promoting builds. It then provides inspiration from Google's SRE practices of using Service Level Indicators (SLIs), Service Level Objectives (SLOs), and Service Level Agreements (SLAs). The document demonstrates how Keptn can automate SLI/SLO-based evaluation to integrate with Jenkins pipelines. It includes demos of using Keptn for self-service SLI validation, automating existing Jenkins tests, and enabling performance as a self-service. The document promotes starting resources on GitHub and joining the Keptn community slack channel
This document provides an overview of ASP.NET MVC and the MVC pattern. It discusses the objectives of understanding MVC, the major concepts including the model, view and controller. It also covers ASP.NET MVC RC1 and how controllers and views work, and concludes that ASP.NET MVC provides testable applications with clear separation of concerns.
Use Layered Model-Based Requirements to Achieve Continuous TestingTechWell
Requirements, test cases, and test data are still generally designed and created the same way they have been for the past thirty years—despite the evolution of testing techniques and tools. Requirements are still specified through written natural language, which leads to ambiguity and poor testability. Test cases are manually designed and are built on incomplete requirements. Test automation requires a human being to first manually create the automation scripts, which then have to be manually maintained sprint after sprint. Alex Martins shares how he helps organizations truly shift-left by using multilayered visual models and CAD-like (computer-aided design) technology to specify requirements such that ambiguity is inherently removed. With unambiguous and complete requirements, developers introduce fewer defects into their code and manual test cases. Join Alex to see how automated test scripts and their required test data can be generated automatically based on the requirements—without manual intervention.
Using Puppet - Real World Configuration ManagementJames Turnbull
Configuration management is the oft-misunderstood (and possibly black) art of managing your IT environment, infrastructure, and costs. Done well it can reduce operational errors and outages, simplify your environment, and help maintain the sanity of your IT staff.
Puppet is part of the bright future of configuration management for heterogeneous Unix systems. It combines automation, a powerful abstraction language, and uses a client-server model that can scale to suit enterprise-size environments. Puppet is written in Ruby and authored by recovering system administrator-turned-developer Luke Kanies.
This session explains why configuration management is important, the benefits configuration management will deliver, and how all of this can be achieved using Puppet. The session also explains emerging best practices in configuration management and addresses:
* What is configuration management? Or why am I here?
* Benefits, risks, and challenges: build fire resistant infrastructure rather than fight fires
* Best practice: how do we do this configuration management magic right?
* Where does Puppet fit in and why should management pay for its implementation?
* Why using Puppet will save you money and help staff retention (although is unlikely to stop world hunger)
* Real world configuration management using Puppet: code, examples, explanations, and using Puppet in anger
* Measuring the results and pocketing the returns
* Where to from here: some ideas about the future (may include wild-arse guesses)
The document discusses various cloud design patterns and principles including CQRS, strangler, pipes and filters, circuit breaker, compensating transactions, static content hosting, gatekeeper, event sourcing, sharding, sidecar, and anti-patterns like busy database, no caching, and chatty I/O.

As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective.

[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...Jason Yip
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.
Lee Barnes - Path to Becoming an Effective Test Automation Engineer.pdfleebarnesutopia
So… you want to become a Test Automation Engineer (or hire and develop one)? While there’s quite a bit of information available about important technical and tool skills to master, there’s not enough discussion around the path to becoming an effective Test Automation Engineer that knows how to add VALUE. In my experience this had led to a proliferation of engineers who are proficient with tools and building frameworks but have skill and knowledge gaps, especially in software testing, that reduce the value they deliver with test automation.
In this talk, Lee will share his lessons learned from over 30 years of working with, and mentoring, hundreds of Test Automation Engineers. Whether you’re looking to get started in test automation or just want to improve your trade, this talk will give you a solid foundation and roadmap for ensuring your test automation efforts continuously add value. This talk is equally valuable for both aspiring Test Automation Engineers and those managing them! All attendees will take away a set of key foundational knowledge and a high-level learning path for leveling up test automation skills and ensuring they add value to their organizations.
Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
In our second session, we shall learn all about the main features and fundamentals of UiPath Studio that enable us to use the building blocks for any automation project.

"$10 thousand per minute of downtime: architecture, queues, streaming and fin...Fwdays
Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

From Developer to Production, Promoting your Webservices

From Developer to Production, Promoting your WebServices
Gerard Davison : Senior Principal Software Engineer
JDeveloper WebServices
3. The following is intended to outline our general
product direction. It is intended for information
purposes only, and may not be incorporated into any
contract. It is not a commitment to deliver any
material, code, or functionality, and should not be
relied upon in making purchasing decisions.
The development, release, and timing of any
features or functionality described for Oracle’s
products remains at the sole discretion of Oracle.
6. Introduction
P is for promotion
• Make it easy to simplify deployments
• Focus on JAX-WS but a lot is applicable to JAX-RPC
in WebLogic
Dev Test Production
7. Introduction
E is for endpoints
• Need to use different instances of a web service in
different contexts
– Versioning a different problem
• Mock services for development
• “Real” services for production
– Can alter real data
– Can cost money per-transaction
8. Introduction
S is for security
• Web Service Security is like pick’n’mix
– Likely to cause indigestion
– Hard to move to a different shop once you’re started.
• Can hard to set up a dev / test / production env
• Less productive
• Policies are the key to making this easier
13. Policies
WS-Policy
• A description of how to communicate
– Stuff that happens to the message after you have sent it
• A meta pointer for other WS-* standards
• Cover a range of technologies
– WS-Addressing
– WS-Security
– WS-ReliableMessaging
– WS-TX
22. Publishing
Weblogic policies
• For JAX-WS only security policy at the moment
– Use @Addressing for WS-Addressing policy
• For JAX-RPC also reliable messaging
• @Policies(@Policy(uri=“policy:….”))
• weblogic-webservices-policy.xml in WEB-INF / META-
INF
23. Publishing
Centralized configuration
• KeyStores, etc… are configured at the server level
• Allow you to assert rather than configure
• Different configuration at each level:
– Dev - no security
– QA - security using internal certificates
– Deploy - security using “gold” certificates
24. Publishing
Annotation to “standard” policies
@WebService
@Policies(@Policy (uri=“policy:SomePolicy.xml”))
public class Hello
{
public String sayHello(String name)
{
return name;
}
}
26. Publishing
Deployment Plan
• JSR - 88
• Weblogic xml file not standard
• Also can override individual files
• The key to dealing with promotion
• No tooling in JDeveloper yet
28. Publishing
Summary
• A mix of deployment and environmental artifacts
• Security declaratively added at class level
• But the configuration done at domain level
30. Consuming
Endpoints
• Abstract WSDL defines the service
• Concrete WSDL tell you where to find it.
• You often want to change location
– Promotion
– Or Multiple deployments in different environments
• But you want a static interface to program against
32. Consuming
WSDLS
• WSDLs also contain policies
• Won’t be read if you just change the endpoint
• Can create a new service object
– Expensive
• Better to use injection in EE case
35. Consuming
Security Tokens
• Simple .properties file in this example
• Should be using a Keystore
– JCEKS rather than default JKS to store SecretKey instances
– Still need to hard code a password but less open to brute
force searching
• Possibly query WebLogic stores for environmental
configuration
– I’m still learning the stack
39. Consuming
Alternatives : UDDI
• Lookup service by UUID
– UDDI 2.0 repository built in to weblogic
– Just edit uddi.properties to enable
• BPEL has support for this directly
• For JAX-WS write your own code to lookup WSDL
• Some BPEL services do WSDL indirection
– Only changes on the BPEL server
43. Conclusion
• Understand and use policies
• Design from the start with promotion in mind
– EE
– DI
– Home grown
• Managing security tokens is finicky
– Store passwords in wallet or keystore
