GlassFish v2 Distributions

GlassFish v2 has a jar installer distribution available for download. A nicer gui-based installer version will also be available at beta and FCS. GlassFish v2 will include developer profile (single JVM) and cluster profile (that includes clustering, in-mem replication for high availability, distributed administration).

(The content and name of profiles are still being discussed)

There are also Enterprise Edition distributions of Sun Application server available from Sun.
