What does OSGi stand for?
Open Service Gateway Initiative
OSGi (Open Service Gateway Initiative) is a Java framework for developing and deploying modular software programs and libraries. OSGi has two parts. The first part is a specification for modular components called bundles, which are commonly referred to as plug-ins.
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 container?
OSGi is a Java framework for developing and deploying modular software programs and libraries. Each bundle is a tightly coupled, dynamically loadable collection of classes, jars, and configuration files that explicitly declare their external dependencies (if any).
Is OSGi still relevant?
OSGI is still the only option when it comes to stable hot deployment in a vm. I started a now job which heavily uses OSGi. It’s great if you just use it for the service registry and capability/requirement model for resolving and validating dependencies.
Is OSGi a Microservice?
OSGI is an application architecture, while microservices is a distributed systems concept. In my experience, microservices offer a number of benefits: Individual microservices are easy to deploy, test, and maintain.
What is OSGi in Liferay?
OSGi (Open Services Gateway initiative) is a framework for developing modular Java applications. OSGi implements a complete and dynamic component model. Liferay 6.2 includes an OSGi runtime in which Liferay plugins that are packaged as OSGi bundles can run.
Is OSGi old?
The modules layer of OSGi architecture is actually about keeping things local and not sharing. OSGi bundles are plain old JARs and, as we know, in normal Java everything in a JAR is completely visible to all other JARs. Bundles are deployed on an OSGi framework, that is, a bundle runtime environment.
Who is using OSGi?
Who uses OSGi? 9 companies reportedly use OSGi in their tech stacks, including Liferay, Business Filemanager, and SYSTHEMIS AG.
What is spring OSGi?
Build a service-oriented application using Spring and OSGi OSGi, also known as the Dynamic Module System for Java, specifies a modular approach to Java application development, as well as a set of standardized methods for managing dependencies between modules.
What is OSGi 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 Liferay?
Liferay, Inc., is an open-source company that provides free documentation and paid professional service to users of its software. Mainly focused on enterprise portal technology, the company has its headquarters in Diamond Bar, California, United States.
What is BND file in Liferay?
The bnd.bnd file describes and configures the module: Bundle-Name: Greeting API Bundle-SymbolicName: com.liferay.docs.greeting.api Bundle-Version: 1.0.0 Export-Package: com.liferay.docs.greeting.api. The module’s name is Greeting API. Its symbolic name–a name that ensures uniqueness–is com. liferay.
What do you need to know about OSGi technology?
OSGi technology is composed of a set of specifications, implementations for each specification, and a set of test compatability kits for each specification that together define a dynamic module system for Java. OSGi provides a vendor-independent, standards-based approach to modularizing Java software applications and infrastructure.
Where can I find OSGi on my server?
OSGI host in the server can find the bundles in a deployment folder, and installs/starts them. You can then enable your web service,rest and other services without restarting the application server. Where I work, we had to pick something in order to continue the project when JBoss-OSGi was declared dead.
What’s the alternative to JBoss-OSGi in WildFly?
Whereas Felix is indeed an alternative to JBoss-OSGI, and your solution could very well work, it does not get us away from OSGI as such. Remember we are trying to align our thinking with the Wildfly 8 world in this regard, a world without OSGI.
