Method Detail

requestServiceOnPort

public void requestServiceOnPort(int repeaterPort)

Handles a request for the CA Repeater Service on the specified port.

The request for CA Repeater services does not always result in an instance of the CA Repeater from being started since various conditions may prevent it. These situations are considered normal and are logged but do not result in any exceptions being raised.

Things that are handled as part of the normal processing:

1. The library configuration has disabled the service.
2. There have been previous requests for the CA Repeater Service on this port which have not yet been cancelled.
3. An instance of the CA Repeater was already started by someone else on the local machine.
4. The attempt to start a new CA Repeater service instance results in an unexpected error.

Parameters:

repeaterPort - the port on which the service is requested.
