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. What you?ll learn Understanding what OSGi is and why we need it Using Spring Dynamic Modules to develop OSGi?based applications An overview of the SpringSource dm Server Setting up and configuring the platform Developing OSGi bundles and web applications for the platform Tracing and monitoring applications running on the platform Who this book is for
This book is for Java developers and deployers who would like to develop modular Java applications using OSGi and deploy them to run on the SpringSource dm Server. You don't need much experience to read this book. However, it assumes that you understand Spring Framework fundamentals and have experience developing Java applications.

Synopsis
Up until now, Spring Framework has had to rely on third party open and closed source deployment tools and application servers like BEA WebLogic, IBM WebSphere, Red Hat JBoss and more. Well, not any more. Spring has finally developed its own deployment tool, SpringSource dm Server.
Pro SpringSource dm Server by Gary Mak is one of the first booksthat cover Springa (TM)s new deployment tool and enterprise Java application server. Spring is still a hot area for todaya (TM)s Java programmer and developer.
Synopsis
I have been a big fan of the Spring Framework since its first release in 2004 and have been using it in almost all my projects. When the application server written by the same company the SpringSource dm Server first came out in April 2008, even though it was in the beta release, I immediately installed it on my machine and tried it out. Note that when it was in the beta release, the dm Server was named the SpringSource Application Platform. When it came to the final release, the name was changed to the SpringSource dm Server, and the SpringSource Application Platform s scope was extended to include a set of SpringSource tools, frameworks, and servers, which includes the dm Server as a core component. When I was trying out the dm Server, I could see already that it was to bring an evolution to enterprise Java application development. The dm Server is built on top of OSGi, a technology specially designed for building dynamic and modular systems in Java. OSGi brings many benefits to Java developers: first, it allows you to divide a system into multiple modules, each of which can be installed, uninstalled, updated, started, and stopped independently; second, it allows different versions of a module to be deployed at the same time so that different applications can choose a version to import at runtime."
