Service-Template Descriptor Element
A service-template
element defines a template for a service
element, simplifying the task of deploying multiple instances of the same service definition. The template should contain a parameterized service
element that is instantiated using a service-instance
element.
This element may only appear as a child of an application
element.
The following attributes are supported:
Attribute |
Description |

---|---|---|

Specifies the identifier for the service template. This identifier must be unique among all service templates in the application. |
Yes |
A template may declare parameters that are used to instantiate the service
element. You can define a default value for each parameter. Parameters without a default value are considered mandatory and values for them must be supplied by the service-instance
element.
Here is an example to demonstrate the use of this element:
<icegrid> <application name="IceBoxApp"> <service-template id="ServiceTemplate"> <parameter name="name"/> <service name="${name}" entry="DemoService:create"> <adapter name="${service}" .../> </service> </service-template> <node name="Node1"> <icebox id="IceBoxServer" ...> <service-instance template="ServiceTemplate" name="Service1"/> </icebox> </node> </application> </icegrid>
