Returns:

String - path where the SR doc for Application Event Logging is stored.

start

public void start(java.lang.String strAETitle,
         java.lang.String strIP,
         int port)
           throws java.io.IOException

Starts the SCP.

Parameters:

strIP - IP at which Server has to be started.

strAETitle - value of AE Title for service provider.

port - port at which Server has to be started.

Throws:

java.io.IOException - throws IOException if IO operation fails.

start

public void start(java.lang.String strAETitle,
         int port)
           throws java.io.IOException

This method will Start the Server on the local host at the port specified.

Parameters:

onAssociateReceive

public void onAssociateReceive(ClientSession objClientSession)

This method notifies when Association Request, Associate Release Request or Abort is received from one of the SCUs. If Association Request is received, Create Association Negotiator which negotiates the request with the existing default association and creates an AgreedAssociation which contains the negotiated association values. AssociationNegotiator returns the Association Response as AssociateAC when request is accepted or returns AssociateRQ is none of the values in Association Request are acceptable. If Associate Release Request is received, Create a Associate Release Response and send the response to the SCU using the respective ClientSession. If Abort is received, An Abort response must be generated and sent using ClientSession.

Parameters:

objClientSession - instance of Client Session.
