After you complete a Project, you need to define an Environment and deploy the Project to the Environment. An Environment is a collection of domains (also known as logical hosts) that house Project components and information about external systems. A deployment Environment can include:
Domain (an instance of the Sun Enterprise Service Bus runtime environment)
Sun Java System Application Server (GlassFish)
Sun JMS IQ Manager
Sun Java System Message Queue
Unified JMS Resource Adapter
External Systems
Environment names can contain letters, numbers, dashes, and underscores. There is no character limit. Spaces and punctuation marks are not valid characters for Project names.
