get detailed soap fault

[El...@lionbridge.com]

i'm coding a web service and i do have a SOAP fault. 
i read in apache's soap doc for troubleshooting this indication about my 
error : 


"The detailed problem may be indicated within the <stackTrace> element 
found inside the <detail> element of the <SOAP:Fault> that was returned 
with the SOAP response envelope."


the problem is that i don't know how to get this stackTrace here is the 
fault detection code i have :

        if(!response.generatedFault()) 
        {
                Parameter result = response.getReturnValue(); // response 
was OK
                System.out.println("Result= "+ result.getValue());
        }
        else {
 
                Fault f = response.getFault(); // an error occured
                System.err.println("Fault= " + f.getFaultCode() + ", " + 
f.getFaultString());
        }

what kind of code should i put to get more details as described in soap 
documentation ?
regards
