Why don't change lifecycle state of mule runtime? - web-services

Question

I want to save some informaion to database when I send a request to mule service.
for this issue: I wrote below config in xml file:
<mule xmlns:vm="http://www.mulesoft.org/schema/mule/vm" xmlns:http="http://www.mulesoft.org/schema/mule/http"

and IpClient class:
public class IpClient implements Callable,ModelNotificationListener<ModelNotification> {
#Override
public void onNotification(ModelNotification notification) {
// TODO Auto-generated method stub
System.out.println("Notification order event: " + notification.getActionName() );
if(notification.getAction() == ModelNotification.MODEL_DISPOSED || notification.getAction() == ModelNotification.MODEL_STOPPED){
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = new Date();
ConnectDB c = new ConnectDB("localhost:3306", "accounting", "root", "");
String sql = " INSERT INTO weather (ip, date, CurrentState) VALUES (?,?,?) ";
PreparedStatement ps = null;
try {
ps = c.getConnnection().prepareStatement(sql);
ps.setString(1, "127.0.0.1");
ps.setString(2, dateFormat.format(date).toString());
ps.setString(3, notification.getActionName());
ps.executeUpdate();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
c.close();
}
}
}
#Override
public Object onCall(MuleEventContext eventContext) throws Exception {
MuleMessage msg = eventContext.getMessage();
String remClient = msg.getProperty("remoteClientAddress", PropertyScope.INVOCATION);
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = new Date();
ConnectDB c = new ConnectDB("localhost:3306", "accounting", "root", "");
String sql = " INSERT INTO weather (ip, date, CurrentState) VALUES (?,?,?) ";
PreparedStatement ps = c.getConnnection().prepareStatement(sql);
ps.setString(1, remClient);
ps.setString(2, dateFormat.format(date).toString());
ps.setString(3, msg.getMuleContext().getLifecycleManager().getCurrentPhase());
ps.executeUpdate();
c.close();
return msg.getPayload();
}
}
this program just works correctly if I start to run service. for example my service run before suddenly it was dissposed(for example my wsdl(http://wsf.cdyne.com/WeatherWS/Weather.asmx?wsdl doesn't work)). my log program saved all records in state of start and after dissposing it works similar. if I stoped my service and run it again it works correctly and it saves all records in dissposed mode.
I don't know how to change my program that it saves correctly in runtime.

Answer 1

The (ill named) Initializer bean is not used as a <component> anywhere in the configuration so there's no way its onCall method will ever get called.
If your intention with:
<notification event="COMPONENT-MESSAGE"/>
is to have the Initializer called for each component invocation you then have to make it implement ComponentMessageNotificationListener (like you made it implement ModelNotificationListener).
