- Field Detail
  - SERVICE_COMPONENT
```
static final String SERVICE_COMPONENT
```
    Manifest header specifying the XML documents within a bundle that contain the bundle's Service Component descriptions.
    The attribute value may be retrieved from the Dictionary object returned by the Bundle.getHeaders method.

    Constant Field Values
  - COMPONENT_NAME
```
static final String COMPONENT_NAME
```
    A component property for a component configuration that contains the name of the component as specified in the name attribute of the component element. The value of this property must be of type String.
    
    See Also:
    
    Constant Field Values
  - COMPONENT_ID
```
static final String COMPONENT_ID
```
    A component property that contains the generated id for a component configuration. The value of this property must be of type Long.
    The value of this property is assigned by Service Component Runtime when a component configuration is created. Service Component Runtime assigns a unique value that is larger than all previously assigned values since Service Component Runtime was started. These values are NOT persistent across restarts of Service Component Runtime.

static final String COMPONENT_FACTORY
```
    A service registration property for a Component Factory that contains the value of the factory attribute. The value of this property must be of type String.

  - REFERENCE_TARGET_SUFFIX
```
static final String REFERENCE_TARGET_SUFFIX
```
    The suffix for the target property of a reference. These properties contain the filter to select the target services for a reference. The value of a target property must be of type String.
