By default, CRX saves repository content to the Tar persistence supervisor. Following DB’s can be used for storing content material – DB2, Oracle, SQL Server, MySQL.
Question forty two. Difference Between Osgi Bundle And Normal Jar File?
OSGi bundles are jar documents with metadata internal. Much of this metadata is inside the jar’s occur, discovered at META-INF/MANIFEST.MF. This metadata, while read through an OSGi runtime box, is what offers the bundle its power.
With OSGi, just because a category is public doesn’t mean you may get to it. All bundles encompass an export listing of package names, and if a package deal isn’t within the export listing, it doesn’t exist to the outdoor world. This permits developers to build an extensive internal magnificence hierarchy and reduce the surface area of the bundle’s API without abusing the notion of package deal-personal visibility. A not unusual pattern, as an example, is to place interfaces in a single package deal and implementations in another, and best export the interface package deal.
All OSGi bundles are given a model wide variety, so it’s feasible for an utility to simultaneously get right of entry to distinctive versions of the identical package (eg: junit 3.8.1 and junit 4.Zero.). Since every package deal has it’s own classloader, both bundles classes can coexist in the equal JVM.
OSGi bundles claim which other bundles they depend upon. This allows them to make sure that any dependencies are met earlier than the package deal is resolved. Only resolved bundles can be activated. Because bundles have versions, versioning may be blanketed inside the dependency specification, so one package can depend upon model junit model three.8.1 and any other package deal rely on junit version 4.0.
In OSGi package, there will be an Activator.Java magnificence in OSGi which is an non-obligatory listener class to be notified of bundle begin and forestall activities.
