Deploy and manage artifacts, examine diagnostic dumps, and examine bundle wiring, either in the live system or from a resolution failure
Equinox console extension
Manage Virgo and deployed artifacts
Plans
define the artifacts that comprise an application, optionally making the application atomic to tie the artifact lifecycles together, and scoped to isolate the application from other applications
Provisioning
Automatically supply the dependencies of an application including bundles, plans, plan archives (PARs), and configurations, from both local and remote repositories
Web container
supports vanilla WAR files, with all their dependencies in WEB-INF/lib, and Web Application Bundles, that import their dependencies via OSGi manifest metadata, via the reference implementation of the OSGi Web Container specification, based on embedded Apache Tomcat and configured using the standard Tomcat server.xml
User Region
Isolates the kernel from user-installed applications and enables admins to focus on application artifacts and their dependencies without seeing those of the kernel as well
Spring
Virgo packages Spring, but can easily be configured to use a different version of Spring
Hot Deployment
Deploy artifacts to Virgo by copying them into the pickup directory, either in archive or exploded form, as an alternative to deploying via the admin console
Legacy Library Support
Enables third party libraries which were not designed for OSGi to function correctly, once they have been converted into OSGi bundles and deployed, through advanced support for thread context class loading, load time weaving, class path scanning, and implicit package use
Advanced Resolution Failure Diagnostics
Resolution failures are analysed and reported in meaningful terms, a dump is taken for offline analysis using the admin console, and the set of bundles being deployed is not committed to the runtime, preserving a cleanly resolved state
Logging
via embedded LogBack, configured in config/serviceability.xml, with a rich set of appenders available out of the box
