Uninformative AxisFault "(0)null"

[Christian Hvid]

Hi list.
I am looking for some information on what possible could cause the  
following exception:

AxisFault
 faultCode: {http://xml.apache.org/axis/}HTTP
 faultSubcode:
 faultString: (0)null
 faultActor:
 faultNode:
 faultDetail:
        {}string: return code:  0

	at org.apache.axis.client.Call.invoke(Call.java:1691)
	at [my code]

I am using generated code from WSDL2Java. I have tried with Axis 1.1  
and Axis 1.2 RC3 - the above trace is from 1.1.

I can see from reading the source code for HTTPSender that the fault is  
likely due to a missing value for MC_HTTP_STATUS_CODE in the message  
context. What could cause that? Is it a server side problem or is it a  
bug in Axis?
