server (Sun GlassFish Enterprise Server 2.1 Administration Reference)

Sun GlassFish Enterprise Server 2.1 Administration Reference

server

Defines a server instance, which is a Java EE compliant container. One server instance is specially designated as a domain administration server (DAS). The admin-service subelement of the config element referenced by a server's config-ref attribute determines whether the server is the DAS.

Note –

Server instances are not the same thing as virtual servers. Each server instance is a completely separate server that contains one or more virtual servers.
