Appliance Datatype

An appliance datatype defines the configuration to be used in the establishment of a Java Virtual Machine. An appliance datatype is an XML document that contains a root appliance element. The appliance element contains an info block, a defintion of the configuration of the virtual machine process, and a codebase reference.

Attributes

key A unique key identitying the deployment entry. Required if the appliance definitionis nested within a plan definition. Not required when an appliance definition is the top-level element (as is the case with an appliance artifact).

Nested Elements

`info`	Descripton of the appliance.
`process`	Java virtual machine configuration.
`codebase`	The application codebase to be deployed on the virtual machine.

Examples

The following sample appliance defines a virtual machine configuration named hello, a virtual machine configuratured with two environment variables FOO and foo, and a codebase referencing a part defintion.

      <variable name="FOO" value="BAR"/>
    </environment>
    <properties>
      <property name="foo" value="bar"/>
    </properties>
  </process>
  
  <codebase uri="link:part:dpml/metro/dpml-metro-sample?message=Hello%20World&port=1024"/>
