public void downloadComplete(int transferToken)
                      throws NFMSException

Specified by:

downloadComplete in interface FileManagementServiceInterface

Throws:

NFMSException

initialize

public void initialize(java.util.Properties p,
                       InitializationObjectInterface io)
                throws java.lang.Exception

This method is to fulfill the instantiation contract.

setSystemProperties

protected void setSystemProperties(java.util.Properties p,

                            throws NFMSConfigurationException

Just because this is messy, it is a separate method. It will set the grid and user info values. or warn if the defaults are used Note that this is made to intercept null values, so that if there is no entry in a properties file and the default is null, it is assumed that NFMS cannot run without this and an exception will be thrown.

Throws:

NFMSConfigurationException
