Chapter 17. Implementing event notification 285

17.4 Implementing the setEventStatus() method

The setEventStatus() method sets the status of an event in the event store. It:

 Checks that the status value is valid and throws the

InvalidStatusChangeException exception if it is not.

 Changes the status of the event that is identified by eventID in the event store.

Example 17-5 shows the setEventStatus() method implementation for the

RMEventStore.

Example 17-5 The setEventStatus() method

public void setEventStatus(String eventID, int status) throws

InvalidStatusChangeException {

RMLogger.trace(CWConnectorUtil.LEVEL4, "Entering setEventStatus");

// obtain connection from connection pool

RMServerRMIInterface connection;

try {

connection = (RMServerRMIInterface) connectionPool.getConnection();

} catch (Exception e) {

CWConnectorExceptionObject c = new CWConnectorExceptionObject();

c.setMsg("Unable to obtain connection to the application");

c.setStatus(CWConnectorConstant.APPRESPONSETIMEOUT);

throw new InvalidStatusChangeException(c);

}

try {

// set status of event in event table to the status provided

RMDataImplementation aDataImpl =

getRMDataImplementationInstance(eventID, status);

connection.updateObject(aDataImpl);

// free up connection from connection pool

connectionPool.releaseConnection(connection);

} catch (Exception e) {

CWConnectorExceptionObject c = new CWConnectorExceptionObject();

c.setMsg("Unable to delete event from the event table");

c.setStatus(CWConnectorConstant.APPRESPONSETIMEOUT);

throw new InvalidStatusChangeException(c);

}

RMLogger.trace(CWConnectorUtil.LEVEL4, "Exiting setEventStatus");

}
