I have a java application with Apache ServiceMix and Apache Camel.
Here is my Camel Spring XML configuration:
<?xml version="1.0" encoding="UTF-8"?>

I send request to external service. When the await time for the external service exceeded limit (currently I simulate it on mock), Camel throws SocketTimeoutException. Then we get Internal Server Error (code 500) in the browser, because application expect valid SOAP response, instead of this get exception and can't parse it. Error:

What I would like to achieve is:
- catch SocketTimeoutException on the Camel site
- then send some SOAP fault response back to application
I have try so far to catch SocketTimeoutException using onException and doCatch, but without success.
EDIT My final Camel Spring XML configuration:
<?xml version="1.0" encoding="UTF-8"?>

And FaultHandler:
public class FaultHandler {
//SOAP response for timeout
public String timeoutExceptionMessage() {
String message = "mySoapMessage";
return message;
}
}
