Enterprises are trusting Spring more and more, and this book leverages OSGi in a way that can “complete” the use of Spring in the enterprise, as OSGi is already being trusted and adopted by IBM, BEA, and others.

The SpringSource dm Server™ is a completely modular, OSGi-based Java server designed to run enterprise Java applications and Spring-powered applications with a new degree of flexibility and reliability. The SpringSource dm Server is based on the SpringSource Dynamic Module Kernel™ (dm Kernel). The dm Kernel provides a module-based backbone for the server, which also harnesses the power of Spring, Apache Tomcat, and OSGi-based technologies.Pro SpringSource dm Server™ is the first book available for learning how to develop and deploy modular applications to run on the SpringSource dm Server 2.0 deployment platform. This book covers everything you need, from basic OSGi concepts to developing and deploying OSGi-based applications on the SpringSource dm Server. This book demonstrates how to migrate an existing web application from a standard WAR to a shared libraries WAR, a shared services WAR, and finally a web module. The topics in this book are introduced by complete and real–world examples that you can follow step by step. Instead of abstract descriptions on complex concepts, you will find live examples in this book.

The Spring framework is growing. It has always been about choice. Java EE focused on a few technologies, largely to the detriment of alternative, better solutions. When the Spring framework debuted, few would have agreed that Java EE represented the best-in-breed architectures of the day. Spring debuted to great fanfare, because it sought to simplify Java EE. Each release since marks the introduction of new features designed to both simplify and enable solutions. With version 2.0 and later, the Spring framework started targeting multiple platforms. The framework provided services on top of existing platforms, as always, but was decoupled from the underlying platform wherever possible. Java EE is a still a major reference point, but it’s not the only target. OSGi (a promising technology for modular architectures) has been a big part of the SpringSource strategy here. Additionally, the Spring framework runs on Google App Engine. With the introduction of annotation-centric frameworks andXML schemas, SpringSource has built frameworks that effectively model the domain of a specific problem, in effect creating domain-specific languages (DSLs). Frameworks built on top of the Spring framework have emerged supporting application integration, batch processing, Flex and Flash integration, GWT, OSGi, and much more.

Discover the Django web application framework and get started building Python-based web applications. This book takes you from the basics of Django all the way through to cutting-edge topics such as creating RESTful applications. Beginning Django also covers ancillary, but essential, development topics, including configuration settings, static resource management, logging, debugging, and email. Along with material on data access with SQL queries, you’ll have all you need to get up and running with Django 1.11 LTS, which is compatible with Python 2 and Python 3.Once you’ve built your web application, you’ll need to be the admin, so the next part of the book covers how to enforce permission management with users and groups. This technique allows you to restrict access to URLs and content, giving you total control of your data. In addition, you’ll work with and customize the Django admin site, which provides access to a Django project’sdata.After reading and using this book, you’ll be able to build a Django application top to bottom and be ready to move on to more advanced or complex Django application development.What You'll LearnGet started with the Django frameworkUse Django views, class-based views, URLs, middleware, forms, templates, and Jinja templatesTake advantage of Django models, including model relationships, migrations, queries, and formsLeverage the Django admin site to get access to the database used by a Django projectDeploy Django REST services to serve as the data backbone for mobile, IoT, and SaaS systemsWho This Book Is For Python developers new to the Django web application development framework and web developers new to Python and Django.

This in-depth Spring-based Java developer code reference has been updated and now solves many of your Spring Framework 6 problems using reusable, complete and real-world working code examples. Spring 6 Recipes (5th Edition) now includes Spring Native which speeds up your Java-based Spring Framework built enterprise, native cloud, web applications and microservices. It also has been updated to now include Spring R2DBC for Reactive Relational Database Connectivity, a specification to integrate SQL databases, like PostgreSQL, MySQL and more, using reactive drivers.Furthermore, this book includes additional coverage of WebFlux for more reactive Spring web applications.  Reactive programming allows you to build systems that are resilient to high load, especially common in the more complex enterprise, native cloud applications that Spring Framework lets you build. This updated edition also uses code snippets and examples based on newest available standard long term support release of Java.  When you start a new project, you’ll be able to copy the code and configuration files from this book, and then modify them for your specific Spring Framework-based application needs. This can save you a great deal of work over creating a project from scratch.   This powerful code reference is a "must have" for your print or digital library. This developer cookbook comes with accompanying source code that is freely available on GitHub under latest Creative Commons open source licensing.  What You'll LearnGet re-usable code recipes and snippets for core Spring, annotations and other development toolsDive into Spring Native which merges the popular Spring and GraalVM for increased performance, speed and reliability of your Spring Framework 6 applicationsExplore Spring R2BC for reactive relational database connectivity with SQLBuild reactive Spring MVC-based web applications and microservices using WebFluxEnhance your enterprise or native cloud applications using Spring Transaction ManagementTest, secure and deploy your Spring applications using reusable code templates availableWho This Book Is ForThis book is for experienced Java programmers, software developers with experience using the Spring Framework.
