Preparing for java 9 modules upload

As the leading full-stack application framework for Java SE and EE, the Spring Framework continues to deliver significant benefits to Java developers, increasing development productivity and runtime performance while improving test coverage and application quality. In this talk, core Spring Framework committer Sam Brannen will provide attendees an overview of the new features in Spring 3.2 as well as a sneak peak at the roadmap for 4.0. Spring Framework 3.2 builds on several themes delivered in 3.1 with a continued focus on asynchronous MVC processing with Servlet 3.0, support for using @Autowired and @Value as meta-annotations, support for custom @Bean definition annotations, and early support for JCache 0.5. Regarding the internals, CGLIB 3.0 and ASM 4.0 have been inlined, and the framework is now built with Gradle and hosted on GitHub. For those interested in testing their Spring-based web applications, Spring 3.2 offers new support for loading WebApplicationContexts in the TestContext framework, and the formerly standalone Spring MVC Test project is now included in the spring-test module, allowing for first-class testing of Spring MVC applications.

Spring 3.1 introduced several eagerly awaited features including bean definition profiles (a.k.a., environment-specific configuration), enhanced Java-based application and infrastructure configuration (a la XML namespaces), and a new cache abstraction. This session will provide attendees a high-level overview of these major new features plus a quick look at additional enhancements to the framework such as the new c: namespace for constructor arguments, support for Servlet 3.0, improvements to Spring MVC and REST, and Spring's new integration testing support for profiles and configuration classes. In addition, this talk will introduce new features under development in the Spring 3.2 roadmap.

Java 9 will introduce a new module system that will provide code encapsulation and a way to explicitly declare dependencies between modules. Some key changes include the ability to define modules using a module-info.java file, and new parameters for javac and java to support modules. There are still some unresolved issues around module declarations, artifacts, descriptors, graphs, reflection, and versioning that need to be addressed prior to final release. The new module system is aimed at addressing problems like large runtime footprints, classpath issues, and lack of visibility controls between packages.

This document provides an overview of the Play Framework for web application development using Java. It discusses the history and architecture of Play, how to set up a Play project, the MVC structure, routing, controllers, views, sessions, assets, hot code reloading, databases, testing, deployment, and scaling. Play uses Netty as its web server, is stateless, supports hot code reloading, and allows building asynchronous and reactive applications. It also has integrations for Akka, WebSockets, caching, internationalization, and more.

The document provides an overview of the Java Platform Module System (JPMS) introduced in Java 9. Key points include: - JPMS addresses issues with strong encapsulation, reliable dependency management, and API evolution in Java applications and libraries. - The module is a new abstraction that more finely controls access and dependencies through package exports and module declarations. - The module path replaces the classpath, and the modularized JDK itself is composed of platform modules. - Projects can begin adopting a modular structure immediately while the ecosystem transitions over time.

The document provides an introduction to Typesafe Activator and the Play Framework. It discusses how Activator is a tool that helps developers get started with the Typesafe Reactive Platform and Play applications. It also covers some core features of Play like routing, templates, assets, data access with Slick and JSON, and concurrency with Futures, Actors, and WebSockets.

With Java 9 modules coming to us soon, you want your existing code to be fully ready for the module system. Making code modular can be a daunting task, but Java 9 comes with a number features to ease migration. This includes automatic modules, the unnamed module and a number of command line arguments. In this talk we will look at examples of migrating real code. It discusses common problems you’ll run into during migration, leading to practical tips and the ability to set realistic goals. It’s also a good way to understand the module system itself and the various migration paths it supports. This talk is an excellent preparation to start migrating your own code. * Understanding modules and the module path * Automatic modules * Mixing classpath and modulepath * Dealing with reflection * Escape switches * Jdeps All topics will be based on examples of often used libraries and frameworks.

This document provides an agenda and summary for a workshop on developing MongoDB applications on OpenShift presented by Shekhar Gulati. The agenda includes getting started with OpenShift, developing a location-aware Java EE application using JAX-RS and CDI for REST services, and MongoDB for the database. The document discusses OpenShift, JAX-RS, CDI, and MongoDB concepts. It also outlines code samples and steps to create and deploy a sample Twitter-like application on OpenShift that supports creating, finding, and geo-searching statuses.

The document compares several Java build tools: Ant + Ivy, Maven, Gradle, and Buildr. It describes their key features such as dependency management, build lifecycles, and conventions. A results matrix shows how well each tool supports desired build features such as compiling Java code, running tests, and property expansion. The evaluation notes that Ant, Ivy and Maven have been around longest but Gradle is promising. Buildr is considered very flexible but has potential platform issues being built on Ruby.

Maven is a build tool that focuses on project structure, dependencies, and conventions. It allows for easy creation of multi-module projects and provides excellent dependency management. Key features include a consistent project structure, dependency management that handles transitive dependencies, and a lifecycle of goals like compile and test. Maven uses a POM file to describe a project's structure, dependencies, and plugins.

The document provides an overview of new features in Java EE 7, including WebSocket support, JSON processing, batch applications, concurrency utilities, simplified JMS API, and enhancements to other Java EE technologies. It discusses 10 top features in more depth and includes code examples. The goal is to help developers get started with Java EE 7.

Maven is a build tool that manages projects and dependencies. It aims to make the build process easy and provide a uniform system. With Java 9, Maven faces challenges due to the module system's differences from the classpath. Specifically, the modulepath does not support all file types like the classpath. This causes issues for Maven which relies on dependencies being on the classpath. Additionally, automatic modules generated from JAR files can cause problems for projects. Maven cannot directly generate module descriptors but tools like Jdeps can assist with initial descriptors. Overall, while challenges exist, Maven can still be used for most projects with Java 9.

The document discusses various aspects of developing modular applications using J2EE, OSGi, and RCP frameworks. It covers: 1. The structure and organization of modules, projects, and dependencies when using different frameworks like J2EE, Spring, Maven, and OSGi. 2. How modules, plugins, and bundles can be developed and packaged for each framework. This includes module/plugin sources, views, packaging, and dependencies. 3. Integration aspects like how to integrate databases, connection pools, templating engines, and more through extension bundles/plugins across frameworks.

This presentation covers some of the aspects that a developer should be aware of while moving to Java 9.

Vignesh Ramesh gives an overview of Java modules in Java 9. Modules allow for strong encapsulation by only exporting certain packages. This addresses issues in Java 8 where all packages were effectively public. The module system solves problems like weak encapsulation and jar hell. Key aspects include module descriptors, exports, requires, and the new jlink tool for creating custom runtime images.

This talk is for a very important new feature in Java SE 9. Code named Jigsaw, this feature modularizes the Java SE platform. The coolest thing we do here is to create a custom JRE Code: https://bitbucket.org/stybz/jigsaw.sty/ PPT: https://www.slideshare.net/mihailstoynov/modules-in-java-finally-openjdk-jigsaw Video: https://www.youtube.com/watch?v=W5LeNPtPrqw

Java 9 is currently scheduled to become generally available in less then 1 year. Perhaps now is a good time to have a closer look at language proposals and API changes in Java 9. There are over 70 proposals targeted to Java 9, we will have a looks at some key ones, starting with java modularity. We will look at some breaking changes and ways to develop both short and long term solutions for adoption of new upcoming version of Java.

The JavaOne presentation describes the new Java 9 features related to Maven and the way how developers can apply these on their Maven projects.

The JFall presentation describes the new Java 9 features related to Maven and the way how developers can apply these on their Maven projects.

Java 9 introduced several new features including JShell, modules, and services. JShell allows developers to test Java code interactively from the command line. Modules allow Java code to be modularized by defining explicit dependencies and encapsulating packages. Services allow modules to discover implementations of an interface at runtime through a service loader. The modularization of Java aims to improve maintainability, security, and performance of Java applications.

Huge JRE images were a huge problem for packaging and deploying small and lightweight tools based on Java. Have you tried to reduce Java runtime images? You will be surprised how well that works. From JDK 9 a minimal image targeting desktops can be as small as 18MB!This is a huge improvement but how does this black-magic work? I will be wowing you with an overview of Java’s custom runtime image tooling and present a interactive demo on how to create a mini Java runtime image file. We bust the myths around Java cloud computing and show you how to embraced Cloud Orientated development with Java. See how the new Java module system works with general patterns for developing a modular Java Cloud application.

The document discusses the impact of Java 9 on Maven projects and provides strategies for Maven and plugins to support Java 9. It outlines changes in Java 9 like the module system and new JAR format that Maven must accommodate. It recommends verifying that plugins work with Java 9 and do not use internal APIs or have duplicate packages. Maven plugins may need to select the module path for compilation in some cases.

Here are the steps to filter the resource properties in the example: 1. Define the my.filter.value property in a filter file (e.g. src/main/filters/filter.properties): my.filter.value=hello 2. Define the command.line.prop property in the pom.xml: <properties> <command.line.prop>hello</command.line.prop> </properties> 3. The settings.offline property will be filtered from the <offline>true</offline> value defined in settings.xml 4. Add filtering configuration to the pom.xml: <build> <filters> <filter>src

This document discusses JBoss Modules, which provides a module system for loading and running modules in Application Server 7. It describes modules as collections of code and resources that implement specific domain requirements. JBoss Modules defines each module as having its own classloader, allowing isolation and preventing conflicts between modules. It manages module dependencies by only loading required imports and exporting specified APIs. The presentation demonstrates how JBoss Modules loads and executes modules quickly and efficiently to serve as the core of Application Server 7.

This document provides an agenda and information for a Java 9/Jigsaw hack day event hosted by the Atlanta Java Users Group. The agenda includes sessions on Java 9 modularization, JLink, migrating non-modular apps to Java 9, and feedback. Presenters will discuss what modularization means in Java 9, including splitting the JDK into named modules that declare dependencies. Attendees will have hands-on exercises and are encouraged to provide live feedback.

Here are the key differences: Reserved words: These are words that have special meaning in Java like class, public, etc. They cannot be used as regular identifiers. Modifiers: Modifiers like public, private, static etc. specify attributes of classes, methods and variables. Package: A package is a namespace that organizes related classes and interfaces. It provides access protection. Libraries: Libraries are pre-compiled classes that provide useful functionality that can be included in programs using import statements. JVM version: The Java Virtual Machine version specifies the Java runtime environment. Programs need to be compatible with the JVM version. JVM: The Java Virtual Machine is an abstract computing machine that

This document summarizes changes to the Java programming language from JDK 9 to JDK 16, including new features and modules. Some key points: - Java has moved to a six-month release cycle, delivering more features faster than before. - Modules were introduced in JDK 9 to improve modularity. Modules group related code and dependencies. - Incubator modules and preview features allow testing of non-final APIs before inclusion in the Java SE platform. - Local variable type inference using 'var' was added in JDK 10 for simpler declaration of local variables when types can be inferred. - Modules, the module system, and tools like jlink and jdeps help manage dependencies

Problem Definition: Building large web applications with dozens of developers is a difficult task. Organizing the engineers around a common goal is one thing, but organizing your code so that people can work efficiently is another. Many large applications suffer from growing pains after just a few months in production due to poorly designed JavaScript with unclear upgrade and extension paths. Scalable JavaScript Application Framework: Yahoo! home page engineer Nicholas Zakas, author of Professional JavaScript for Web Developers, introduced front-end architecture for complex, modular web applications with significant JavaScript elements.

With the release train we can expect a new version of Java every 6 months. This means that tools like Maven should try to keep with this pace. Especially Java 9 came with some new features, and Maven managed to support these features. Maven found an elegant solution to work with modulepaths and classpaths without any need for developers to specify which jars belongs where. This session will highlight the most important features developers should know to work with Java 9 and 10, combined with some practical tips and warnings.

Covers the common issues seen when migrating from Java 8 to Java 9. This deck shows simplified examples of the issues and code snippets of how to address them.

Presentation given on OpenJDK project Penrose by Tim Ellison and David Bosschaert at Penrose BOF at JavaOne 2012

The talk will cover a bit of background first to set things up: what is a module, why do we need a module system, summary of Java's existing support for modularity. Then it will move on to give a comparison of OSGi's and Jigsaw's dependency models. Pros and cons of each model in different environments will be discussed. Finally, opportunities and challenges for interoperability: from the perspective of both application developers (who may need to integrate modules from both kinds) and from library module developers (who may need to target both module systems)

The document discusses modularization in Java 8 and OSGi. It describes what modules are and why they are needed, including for managing dependencies and versioning. It outlines the characteristics of a good module system and compares how Java 8's Project Jigsaw and OSGi handle modularization. Key points include how both aim to address issues like class loading performance and dependency management, but OSGi has existing tools and does not require language changes.

JavaOne 2016 JMS is pretty simple, right? Once you’ve mastered topics and queues, the rest can appear trivial, but that isn’t the case. The queuing system, whether ActiveMQ, OpenMQ, or WebLogic JMS, provides many more features and settings than appear in the Java EE documentation. This session looks at some of the important extended features and configuration settings. What would you need to optimize if your messages are large or you need to minimize prefetching? What is the best way to implement time-delayed messages? The presentation also looks at dangerous bugs that can be introduced via simple misconfigurations with pooled beans. The JMS APIs are deceptively simple, but getting an implementation into production and tuned correctly can be a bit trickier.

JavaOne 2016 This session provides 50 best practices for Java EE 7, with examples. The best practices covered focus primarily on JPA, CDI, JAX-WS, and JAX-RS. In addition, topics involving testing and deployment are covered. This presentation points out where best practices have changed, common misconceptions, and antipatterns that should be avoided. This is a fast-paced presentation with many code samples.

Configuring and maintaining a continuous integration environment is quite a bit of work. It requires ongoing resources both in terms of manpower and hardware infrastructure. As an application evolves so does the number of ongoing projects. The challenge is creating a scalable continuous integration environment which does not impede development and can handle the complexities of Java EE testing. This session covers how to setup and configure a cloud-based continuous integration environment for Java EE applications. The presentation will focus on demonstrating how to use Atlassian Bamboo running on AWS to build and test a Maven/Gradle Java EE project that uses Arquillian for testing. Topics that will be covered include creating a custom AWS VM for use with Bamboo, creating an Amazon VPC (Virtual Private Cloud) along with test database using Amazon RDS. The presentation will delve into the specifics of testing EJBs, WebSocket endpoints, RESTful web services, as well as performing load testing in this environment. Security, cost control, and build monitoring will be covered as well.

Java is a general-purpose language and is not particularly well suited for performing statistical analysis. Special languages and software environments have been created by and for statisticians to use. Statisticians think about programming and data analysis much different from Java programmers. These languages and tools make it easy to perform very sophisticated analyses on large data sets easily. Tools, such as R and SAS, contain a large toolbox of statistical tools that are well tested, documented and validated. For data analysis you want to use these tools. In this session we will provide an overview of how to leverage the power of R from Java. R is the leading open source statistical package/language/environment. The first part of the presentation will provide an overview of R focusing on the differences between R and Java at the language level. We’ll also look at some of the basic and more advanced tests to illustrate the power of R. The second half of the presentation will cover how to integrate R and Java using rJava. We’ll look at leverage R from the new Java EE Batching (JSR 352) to provide robust statistical analysis for enterprise applications.

Apache Cordova is used to wrap HTML5 applications into native mobile applications that can access device capabilities. A demo application was shown that used Cordova for the mobile portion and Java EE 7 on the server side. Key technologies discussed included Cordova plugins, RESTful web services, Java API for JSON, and Java API for WebSockets for bidirectional communication between the mobile app and server. jQuery Mobile was also mentioned as a potential UI framework.
