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 |
Required |
|---|---|---|
|
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>
