Admin Console

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


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


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


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


via embedded LogBack, configured in config/serviceability.xml, with a rich set of appenders available out of the box
