Spring is a framework that promotes development of looselycoupled/ highly-cohesive objects through dependency injection and interface-oriented design. OSGi is a framework specification that promotes development of loosely-coupled/ highly-cohesive application modules through services and interface-oriented design. Seems like a match made in heaven! Spring Dynamic Modules (Spring-DM) brings Spring and OSGi together to enable a declarative service model for OSGi that leverages Spring’s power of dependency injection.

This reference card will be your resource for working with Spring- DM to wire together OSGi services and ultimately building modular applications. You may be interested to know that Spring-DM is the basis for the SpringSource dm Server, a next-generation application server that embraces modularity through OSGi. What’s more, the upcoming OSGi R4.2 specification includes a component model known as the OSGi Blueprint Services that is heavily influenced by Spring-DM. The star player of Spring-DM is a bundle known as the Spring- DM extender. The Spring-DM extender watches for bundles to be installed and inspects them to see if they are Springenabled (that is, if they contain a Spring application context definition file).

When it finds a Spring-enabled bundle, the extender will create a Spring application context for the bundle. Spring-DM also provides a Spring configuration namespace that enables you to declare and publish Spring beans as OSGi services and to consume OSGi services as if they were just beans in a Spring application context. This declarative model effectively eliminates the need to work with the OSGi API directly. One of the nice things about Spring-DM is that you do not need to include it in the classpath of your OSGi bundles or even reference it from those bundles. Installing Spring-DM involves two parts: • Installing the Spring-DM and supporting bundles in your OSGi framework • Adding the Spring-DM configuration namespace to your bundle’s Spring configuration XML files You can download Spring-DM from. The distribution comes complete with everything you need to work with Spring- DM, including the Spring-DM extender bundle and all of its dependency bundles.

Installing the Spring-DM Extender Bundles There are several means by which you can install bundles into an OSGi framework, depending on the OSGi framework and any add-ons or tools you may be using. But the most basic way is to use the “install” command that is available in most OSGi framework shells.

Use tools to help install bundles Installing bundles using the “install” command should work with almost any OSGi framework, but it is also quite a manual process. Pax Runner (paxrunner.ops4j. Bookworm Adventures 2 Apk For Android Free Download on this page. org) is an OSGi framework launcher that takes a lot of the tedium out of installing bundles.

Just use Pax Runner’s “spring dm” profile:% pax-run.sh --profiles=spring.dm The Spring-DM Configuration Namespace Schema URI: Schema XSD: When it comes to declaring services and service consumers in Spring-DM, you’ll use Spring-DM’s core namespace. To do that, you’ll need to include the namespace in the XML file.. Spring’s “beans” namespace is the default namespace, but if you know that most or all of the elements in the Spring configuration file will be from the Spring-DM namespace, you can make it the default namespace. Overriding the context configuration location By default, the Spring-DM extender looks for all XML files located in a bundle’s META-INF/spring folder and assumes that they’re all Spring context definition files that are to be used to create a Spring application context for the bundle; however, if you’d like to put your context definition files elsewhere in the bundle, use the Spring-Context: header in the META-INF/ MANIFEST.MF file. For example, if you’d rather place your Spring configuration files in a directory called “spring-config” at the root of the bundle, add the following entry to your bundle’s manifest: Spring-Context: spring-config/*.xml This Spring context file can be named anything, but it should be placed in the Pig Latin translator bundle’s META-INF/ spring directory.
