What is OSGi framework in AEM?
OSGi is a fundamental element in the technology stack of AEM. It is used to control the composite bundles of AEM and their configuration. OSGi “provides the standardized primitives that allow applications to be constructed from small, reusable and collaborative components.
What is OSGi framework?
OSGi defines a dynamic module system for Java™. The OSGi service platform has a layered architecture, and is designed to run on various standard Java profiles. OSGi Applications deployed to WebSphere® Application Server run on an Enterprise Java profile that is provided as part of the server runtime environment.
What are the benefits of OSGi in AEM?
The main benefits of using OSGI are: It reduces the complexity of the system by having everything in bundles. It makes the components loosely coupled and easy to manage since they can be installed, deleted, updated, started, and stopped at run time.
What is difference between jar and OSGi bundle?
There is basically no difference. A JAR is a bundle and a bundle is a JAR, the formats are identical. However, a useful bundle requires OSGi metadata in its manifest so that an OSGi framework can manage the visibility of classes between bundles.
What is OSGi component in AEM?
An OSGi service is a Java class or service interface, along with a number of service properties as name/value pairs. The service properties differentiate among different service providers that provide services with the same service interface.
What is MSM in AEM?
Multi Site Manager (MSM) allows aem developers to create copy of existing site and automatically update the copy when changes are done to the source site.
What is OSGi used for?
The OSGi component system is used to build any type of application ranging from the simple to highly complex applications like IDEs, application servers, email systems, content management systems, application frameworks, residential gateways and onboard telematics systems.
What is OSGi in simple terms?
Simply said, OSGi is a dynamic module system for Java. It defines means to install, uninstall, update, start and stop modules. Those modules are called bundles, but are, in their simplest form, actually Java jar files with a special Manifest.
What are the advantages of OSGi?
The OSGi framework provides the following benefits: Applications are portable, easier to re-engineer, and adaptable to changing requirements.
Why is OSGi used?
OSGi facilitates creating and managing modular Java components (called bundles) that can be deployed in a container. As a developer, you use the OSGi specification and tools to create one or more bundles. OSGi defines the lifecycle for these bundles. It also hosts them and supports their interactions in a container.
What is the difference between package and bundle in AEM?
Packages will create a single reservation ID but bundles will create one reservation ID per reserved resource. Packages reserve all included resources for the same duration. Packages can only include resources from the same planyo site, bundles can include resources from the entire meta site.
What are OSGi components?
OSGi Component — FetchTODO As we discussed earlier, an OSGi component is the entity whose lifecycle will be managed by the OSGi container. To make a class act as component, we annotate it with @Component . We can start, stop and configure the component using Apache Felix Web Console.
What is OSGi in AEM?
What is Osgi in AEM? OSGi is a fundamental element in the technology stack of Adobe Experience Manager (AEM). It is used to control the composite bundles of AEM and their configuration. OSGi “provides the standardized primitives that allow applications to be constructed from small, reusable and collaborative components.
What is the AEM Felix framework?
AEM houses a powerful open source framework in its technology stack, Apache Felix. Felix is a open source implementation of OSGi. OSGi provides a way to manage bundles and their configurations.
What are the OSGi configuration settings?
Details of certain important settings are listed under OSGi Configuration Settings. The Web console in AEM provides a standardized interface for configuring the bundles. The Configuration tab is used for configuring the OSGi bundles, and is therefore the underlying mechanism for configuring AEM system parameters.
