\page MoMaService \section rules_com_highqsoft_moma_rules_jvmservice_MoMaLauncher \addindex MoMaService MoMaLauncher Package \b com.highqsoft.moma.jvmservice The MoMaLauncher class is used to start MoMa processes triggered by external events. The event handler used to trigger a new MoMa process must implement the interface com.highqsoft.moma.jvmservice.EventHandlerIF. The MoMaLauncher can either be started from command line or as a Microsoft Windows Service using the MoMaService class. Each MoMaLauncher can handle a single event queue, but different types of events within the queue. For each type of event there must be one job file to execute. The MoMaLauncher expects the arguments -IniFile \. All other configuration items are read from the properties file. This file contains also the configuration of the event handler and the whole content is passed to the event handler. The properties used to configure the MoMaLauncher itself are \li \b MoMaLauncher.EventHandlerClass
The name of the class that implements the EventHandlerIF. \li \b MoMaLauncher.EventTypes
A list of event types separated with commas. For each event type in the list a property named EventType.\.MomaControlFile must exist that contains the full qualified name of a MoMa job file. \li \b MoMaLauncher.Logfile
The name of the logfile where the Messages from the MoMaLauncher and the event handler are stored. \li \b MoMaLauncher.EmptyQueueSleepMilliseconds
If there is no event waiting in the queue the MoMaLauncher waits this amount of time until it checks the queue again. The default value is 10 seconds. \li \b MoMaLauncher.MinEventAgeSeconds
Defines the delay before an event is processed. A value greater than 0 is only needed if the event is written before the data to process are available. \li \b MoMaLauncher.MaxRetryCount
Defines the maximum retry count for failed events. If the retry count of an event has reached this number the MoMaLauncher does not try to process it again. \li \b MoMaLauncher.RetryIntervalSeconds
Defines the number of seconds between two attempts to retry failed imports. \li \b EventType.\.MomaControlFile
The job file used if an event of type \ was found. There must be one entry for each event type configured in \e MoMaLauncher.EventTypes. All Job files are parsed and validated during startup. If you need to change one of the job files the MoMaLauncher must be restarted!
