Hi,
I want to listen to all the all the errors when my message passes through
bus. After doing some reading on forum, I think I should add a
messageExchangeListener which will listen to all errors.
I got this listener by Bruce's postpublic class ExceptionListenerService
implements ExchangeListener {
public void exchangeAccepted(ExchangeEvent event) {
// TODO Auto-generated method stub
}
public void exchangeSent(ExchangeEvent event) {
MessageExchange me = event.getExchange();
Exception exception = null;
if (me.getError() != null) {
exception = analyzeException(me);
}
me.setError(exception);
}
/**
* This method abstracts any special exception handling behavior.
*
* @TODO Abstract this further using pluggable strategies to hold the
* custom functionality. Then we just stuff the strategies that are
* named in the servicemix.xml config into an array and just walk the
* array, invoking the execute method on each strategy.
*
* @param error The exception that was thrown
* @param endpointName The name of the endpoint that threw the exception
* @return
*/
private Exception analyzeException(MessageExchange me) {
Exception error = me.getError();
String serviceName = me.getEndpoint().getServiceName().toString();
String endpointName = me.getEndpoint().getEndpointName();
String errorMessage = error.getMessage();
// Add calls to custom processing here
StringBuilder newErrorMessage =
new StringBuilder("The following error was caused by service:
[");
newErrorMessage.append(serviceName != null ? serviceName : "null");
newErrorMessage.append("] and endpoint: [");
newErrorMessage.append(endpointName != null ? endpointName :
"null");
newErrorMessage.append("] ");
newErrorMessage.append("Original error: ");
newErrorMessage.append(errorMessage);
return new Exception(newErrorMessage.toString(), error);
}
}
Now how can I configure it in servicemix?
please help
Regard,
Pratibha
