resolveComponentURI

protected Component resolveComponentURI(java.lang.String componentURI)

Resolves the specified URI to a Component using the compositeActivator. There are two cases that we need to handle:

• URI containing just Composite name(s) (i.e. no Service name specified)
• URI containing Composite name(s) and a Service Name

Parameters:

componentURI - The URI of the Component to resolve

Returns:

The Component for the specified URI or null if not founds

resolveServiceURI

protected ComponentService resolveServiceURI(java.lang.String bindingURI,
                                             Component targetComponent)

Examines the Services on the specified Component and returns the Service that matches the specified Binding URI.

Parameters:

bindingURI - The Binding URI to resolve on the Component

targetComponent - The Component containing the Services

Returns:

The Service with the specified serviceName or null if no such Service found.
