> I am investigating the exception handling capability of Axis and created a sample web
service.
> My axis web service is throwing an exception wrapped inside an AxisFault. The service
uses rampart for security.
> This is what is in the service class method:
>         if (devices == null) {
>             throw new AxisFault(new NullPointerException("No devices have been rerieved"));
>         }
> and the method throws AxisFault.
> When i invoke this call and no exception is returned, the result is obtained without
a problem.
> However, when I invoke the axis client which calls this service with parameters in a
way that I expect to get the NullPointerException above, I get the output stack shown below.

> Something seems wrong with the way the client api is parsing the fault from the soap
body. And why do I see the RampartException anyway?
> I've caught the AxisFault that is being thrown and it has no properties or the NullPointerException,
all is has is this:
> org.apache.axis2.AxisFault: Error in extracting message properties; nested exception
is:
>         org.apache.rampart.RampartException: Error in extracting message properties
> I had posted the same on the user list and was asked to file a JIRA.
> Thanks,
