About this task
WebSphere® eXtreme Scale OSGi support
allows you to deploy the product in an OSGi framework, such as Eclipse
Equinox. Previously, if you wanted to update the plug-ins used by
eXtreme Scale, you had to restart the Java virtual machine (JVM) to
apply the new versions of the plug-ins. With the dynamic plug-in support
provided by
eXtreme Scale and
the ability to update bundles that the OSGi framework provides, you
can now update the plug-in classes without restarting the JVM. These
plug-ins are exported by
bundles as services.
WebSphere eXtreme Scale accesses the service
by looking up the OSGi registry. In the OSGi service platform, a bundle
is a Java archive (JAR) file that contains Java code, resources, and
a manifest that describes the bundle and its dependencies. The bundle
is the unit of deployment for an application.
