Custom exception missing extends Exception in jaxb generated classes.

[Srinivas Kasani]

Hi,
I'm using a WSDL first approach with apache cxf 2.2. I have a custom defined exception defined in WSDL. When i'm generaetd the stubs, for the exception class, I donot see header called which extends from Exception in the generated stub.

Example:
<soap:fault name="SecurityException" use="literal"/>

In the generated classes, I see the generated class as

public class SecurityException {

}

I was exception to see, something like public class SecurityException extends Exception instead.
Is there any special parameter I'm missing to specify. Please advice.

Thanks,
