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.

This book fully acquaints readers with the suite of tools, extensions, plug-ins, modules and more that they will need for server-side, enterprise and even mission critical, Java-based transaction-based systems that can be highly scalable and complex.

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.

This book contains a collection of code recipes and templates for learning and building Hibernate solutions for you and your clients. There are many books focused on learning Hibernate, but this book takes you further and shows how you can apply it practically in your daily work.
