Connection exception

Hi people. I'm doing a data migration script, using Java, from data in
phpgroupware, to opengroupware. I take data from the phpgroupware database
using sql, and I create the dates, contacts and tasks in ogo using xmlrpc,
but there is a problem and this is the exception:


..org.opengroupware.jogi.ogo.ConnectionException: Address already in use:
