1. Register GlassFish and start it up from Services tab.
2. Expand Resources/JDBC node under GlassFish and then JDBC Resources or Connection Pools
3. Right-click on a single JDBC resource/connection pool node
=> It would be useful to have an action in the popup menu that would register the JDBC connection associated with this node in the IDE's Databases node. If the connection is already registered, there should be an action to jump to (select) this connection.
Targeting for next release.
