> Hi there,
> We have a simple SOAP layer that returns data pulled from the DB using Axis.
> Nothing special here.
> In our testing, one of the objects happened to have an invalid XML 1.0
> character (0x10) in its description field. As it's not an application Fault
> (our application currently doesn't check for it. It no doubt should,
> obviously), Axis2 wasn't aware of it until it's notified by the Woodstox
> BufferingXMLWriter of an invalid character (through IOException). Axis2
> caught the exception (at , and raised an AxisFault. It then proceeded to
> send the Fault as its own message (envelope) back to the client. All is
> well, except that Axis2 was in the middle of writing out response provided by
> the business application. That led to a corrupted byte stream that contained
> a partial, not well-formed envelope, followed immediately by the Fault
> envelope. Something to the effect of a purging (not flushing) to clear the
> output stream before sending out the Fault message would seem desirable.
> It may not be so bad if the client receives such a corrupted stream, and
> throws some sort of error. The Fault message becomes meaningless, obviously,
> which isn't great either. But, what's worse is that the Axis2 client
> (ServiceClient.sendReceive) actually was able to parse the corrupted byte
> stream, and somehow considered the Fault message be the content of the last
> XML element that contained the invalid character. Now, that's really bad.
> This may have been logged in JIRA, but I couldn't seem to find it.
