@MiroslavResetar, JavaCro14, 13.5.2014.

• LIKE MY IDEA is a social business solution that provides gathering
organizational ideas in just one place ... with lean thinking and visual
management, leading to continuous improvement process.

Pakiranje release-a
• Što moramo sve upakirati
• Aplikacija (lmi-rest EAR)
• Event handler (lmi-eh) biblioteka
• DDL
• Dokumentacija (Installation Guide)
• Connections customizations
• Jython wsadmin skripte
• Linux shell & Windows batch skripte
• Groovy instalacijska skripta
• Biblioteke potrebne za instalaciju

Maven Assembly Plugin
• „... build distribution "assemblies" easily, using one of the
convenient, prefabricated assembly descriptors”

Priprema servera za
instalaciju aplikacije
• Potrebno je kreirati resurse
• Shared library (lmi-eh)
• Work Manager
• JMS resurse (queue, JNDI)
• JDBC Datasource
• Promijeniti nekoliko config datoteka
• Konfiguriranje IBM Connectionsa se radi kroz XML datoteke
• check out
• modify
• check in

Instalacija aplikacije
• Kopiranje shared biblioteke lmi-eh
• Dodavanje iste kao shared u News aplikaciju
• Instalacija lmi-rest EAR aplikacije
• Update samo jedne datoteke u Blog aplikaciji
• blog template

Kako ubrzati instalaciju?
• Automatizacija
• Sve što je moguće napraviti programski, napraviti tako
• Lakše je kada aplikacijski server ima podršku za
automatizaciju
• „The wsadmin tool runs scripts. You can use the wsadmin
tool to manage application servers as well as the
configuration, application deployment, and server runtime
operations.”
• Ništa ne „uklesati u kamen”
• modularno i konfigurabilno

kontrolni program
• Zašto Groovy?
• Java je već instalirana na serveru
• Za rad dovoljan groovy-all.jar
• Out-of-the-box Commons CLI
• Samo jedna skripta za Linux/Win
• Na raspolaganju sve Java biblioteke
• Konfiguracija kroz property datoteku
• Dobra podrška za pokretanje sistemskih procesa
• groovy -e
"'ls'.execute().waitForProcessOutput(System.out,
System.err)"

Prilagodbe Connectionsa
• Zadatak: kopirati resurse (customizations) u direktorij
• Opasnosti: resursi već mogu biti u istoj putanji
• Rješenje: Groovy AntBuilder

JAXB – Update XML
konfiguracije
• Connections widgeti se registriraju ažuriranje XML
konfiguracije
• Maven jaxb2-maven-plugin (xjc, .xsd -> .Java)

Konferencija Javantura Zagreb 2014 by HUJAK Java na klijentskoj strani – ima li budućnosti? by Ivan Vučak U proteklih nekoliko godina Java se pozicionirala kao tehnologija izrade serverskih komponenti, ali kao da se zaboravlja da se Java koristila iza izradu Rich Internet aplikacija (RIA). Da li je Java konkurentna na području RIA te koliku ulogu u tome imaju razni sigurnosni standardi? Kako održavati postojeće RIA sustave uz općenito nepovjerenje ostalih sustava prema Java klijentskim aplikacijama? U ovom predavanju bavit ćemo se usporedbom Jave s ostalim tehnologijama te pokazati zašto strepimo kod svakog Java update-a.

Non-functional testing is an important, but often ignored step in the process of developing applications. Gatling is a tool that enables us to simulate load, performs the associated measurement and presents the results of the performance testing. Why is Gatling detected by the ThoughtWorks radar? Because it is based on Akka, Netty and Scala technologies and so this lecture will show that writing performance scripts don’t have to be boring. With the concept and methodology of performance testing, using Gatling, the author will present personal experiences from previous projects testing the JVM applications.

Nowadays when REST is popping out everywhere and every single API is a REST service, a single mention to RPC seems like a time travel into the past. In the shadows of REST's glory, Google has quietly made and open sourced it's RPC framework (intuitively) called gRPC under the slogan "boilerplate to high-performance scalable APIs". Considering popular names already using it, looks like there's much more to a story than it seems. What's it all about? What's wrong with JSON and REST? And why does HTTP matter?

The Internet of things (IoT) is a scenario in which objects are provided with unique identifiers and the ability to automatically transfer data over a network without requiring human interaction. The idea is that everything is connected, and is able to provide and use data. So, a water sprinkler will check the weather forecast before watering the lawn, a smart bracelet will notify the ambulance if the person wearing it has a heart attack, and the heating in our apartment will start once it gets a notification from our car that we have left work and are heading home. The presentation will give an overview of enabling technologies for the Internet of things, focusing on the cloud platforms that allow the storage, analysis and usage of device provided data. We will describe the services that such platforms provide, show you how to use them with your own devices, and overview a couple of the most widely used ones.

When developing software, due to short implementation deadlines, there is very little room for what is considered a key stage: testing. This means testing needs to be efficient and simple for implementation and execution. Selenium is a testing framework for web application, which uses DOM interaction for testing. It can be easily integrated with JUnit, and with the help of WebDriver API, testing for all popular web browsers can be simulated, in addition to web applications adapted to mobile devices. Also, it can be used in interaction with a large number of programming languages. Testing is done from a point of view of the application user, which enables realistic testing scenarios and acceptance tests. In our presentation, we will show an example of using Selenium and present its most important functionalities.

Vaadin is a framework for building rich web applications. Vaadin features server-side architecture where all of the business logic is located on server and only presentation layer is located on client side. Server-side architecture can be advantage since session state is stored on server. Statefulness can also be a disadvantage since server is frequently contacted. Obviously, the big mystery is scalability which is the main „pros and cons“ Vaadin battle. The question is, is Vaadin capable of satisfying the needs of an application that requires thousand of concurrent active users.

Software developers historically obsess over the tools they use, and even the smallest software endeavor must have at least some supporting infrastructure. Amphinicy has been in this business for a while, so we’ve tried our share of infrastructure tools; some we’ve kept, some we’ve abandoned, and some we’ve written ourselves. Due to some of our specific clients, we probably run more infrastructure than most, and we pride ourselves on almost all of it being open source. This talk will explore how we deal with software development from an infrastructure and processes perspective – from our repository and build system, through continuous integration and integration testing to formalized code reviews and ideas we might work on next.

Drools is a business rule management system (BRMS) with an inference based engine, using an enhanced implementation of the Rete algorithm. Business rules implementations are aimed mostly at developers. However, it is sometimes needed that these rules are readable and understandable by the business analysts. Ideally, they should be able to change rules or even write new ones. Decision table as a form of human-readable rules involve business analysts in creation and maintenance of rules. Managing rules in a spreadsheet format is very applicable for business analysts since they already use them. An important aspect of business rules is their readability and user friendliness. Looking at a rule, you should immediately have an idea of what it is about.

Since the Java 7 update 40 Java Flight Recorder and Mission Control are shipped with the JDK. With these tools it is possible to profile an application not only on a developer computer, but also on production. The overhead of profiling with Flight Recorder is minimal, which allows us to use the profiler on any environment. These profiling tools are relatively new and unfortunately unknown to a lot of developers. This talk will give an overview of Java Flight Recorder and Mission Control so the audience can start profiling their applications afterwards.

Continuous Integration has improved software development process, while deployment of software often does not get as much attention. In this presentation we describe an approach for efficient cloud deployment of highly distributed system which can be quite complex to deal with. DeploymentManager(DM) tool is developed as internal project of Infobip company for managing large number(cca. 250 instances) of internal services in our data centers using automated deployment and controling load balancing software(Apache, HaProxy). With DM tool it is possible to deploy build(jar, war, egg…) on any environment(Windows, Linux) in max 5 minutes, without technical knowledge about deployment process, making Continuous Delivery process fast and simple.

To deliver optimal user experience, web applications should have simple navigation and browsing, automatic resolution adjustment to suit the user (whether on mobile devices or desktop computers), minimal loading times, SEO, etc. All of these must be considered when designing a web application today. The Java/JEE ecosystem provides a number of frameworks that can facilitate the development of web applications, but have difficulties fulfilling the above-mentioned conditions. On the other hand , more and more web developers advocate “Single page” applications and JavaScript frameworks which boost development. How to take advantage of existing services (EJB) and introduce them into the world of JavaScript programming (JSON)? Should all data access be organized through an API?

GWT (formerly “Google Web Toolkit”) stands today as a proven and robust Java framework for rich Internet applications used both as a standalone framework and as a base for some higher level frameworks like Vaadin and Errai. From its inception in 2006. it went through one major overhaul in 2009. (GWT 2.0) and after apparently dormant last few years is successfully open sourced and is preparing for next major revision – GWT 3.0 planned for release in summer 2014. This presentation covers major objectives for version 3.0 like Java 8 compatibility, new widget model based on Web Components, better JavaScript integration through JS Interop and new development mode called SuperDevMode.

Modern business is exposed to various influences, inspiring and confining. This means that you must take into account their economic interest (e.g. profit), its social role (social responsibility) and relationship to the environment (ecology). Applying best practices stated in the ISO standards helps firms to find harmony in all of these requirements and ensure that you develop in the long terms. Certifying those management systems company receive independent confirmation of its authenticity, which raise their reputation with customers, employees and other stakeholders. The paper gives an overview on the expected demand in the near future and possible applications in the industry, particularly in the business of software development.

Scala is an alternative JVM language with both object-oriented and functional programming paradigms. Scala development with the Java EE 7 platform is definitely possible and can be a pleasant experience. If you have uncertainty about how Scala can fit around the Java EE 7 platform, then this session aims to illustrate the huge benefit that Scala adoption can bring to the platform. Many other developers are taking advantage and the challenge of the JVM’s capability of being a vessel for multi-language programming. You no longer have to write every single project using Java, even if you like Lambdas experiences. For the developer and engineering terms that feeling a little braver than usual, Scala is attractive as it is strongly typed and lets you set the gauge on how object oriented or how functional you want to be. You will learn how to reuse the annotations and creating Scala plain object safely and concisely. This session will highlight and contrast the experience I had developing Scala solutions with Java EE, and there will be plenty of advice about using the functional programming features against the Java object oriented API. Scala language overview Java EE 7 architecture and design WildFly 8 application server Using Gradle as a build tool How to create beans in Scala with dependency injection JAX-RS endpoints Servlet Endpoints JMS Messaging Scala adoption advice and hints for sustainable team development

It feels like we have building web sites and applications for centuries, doesn’t it? However, we know that this is so untrue, because the web is only 25 years old since Sir Tim Berner’s Lee great proposal at CERN. The impetus of online design and development has changed, we now talk about the Digital Worker, the Digital environment and we about building web applications and ecommerce applications that are user friendly and customer centric. So what has this all to with the humble Java application developer? The answer is everything. We must be explicit in the software that we write, lean and agile in the way we write, and whilst making sure the take full advantage of the underlying Java platform. In fact, because we have this magnificent Java Virtual Machine and open standards like Java EE, we can continue build quality, robust and sustainable software for all our stakeholders and business users.
