All...
I've got a very puzzling problem issue with CXF v2.0.1. I implemented a
SOAPHandler that logs all the SOAP messages being sent over the wire. It's
very similar to the one that ships as an example in the CXF distribution
except that I'm logging to a log4j Logger.
What's strange is that in one case the behavior of my SOAP service changes
depending on whether the logging is enabled or not! (The SOAPHandler itself
is enabled always, just the logging of the messages is enabled/disabled at
runtime.) Even stranger, is that when the logging is enabled the service is
working fine, but when the logging is disabled, the service errors with an
unmarshalling error (see below).
Logging a SOAP message shouldn't be affecting the parsing of a message in
any way. Here's the relevant code:
private void log(SOAPMessageContext smc)
{
if (!log.isTraceEnabled()) return;
Boolean outbound =
(Boolean)smc.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
SOAPMessage msg = smc.getMessage();
try
{
if (outbound.booleanValue())
{ los.write(">\n".getBytes()); }
else
{ los.write("<\n".getBytes()); }
msg.writeTo(los);
los.flush();
}
catch (Exception e)
{ log.error(e.getMessage(), e); }
}
It seems to me that either SOAPMessageContext.getMessage() or
SOAPMessage.writeTo() must have some sort of sideaffect?!? Surely this
can't be intended?
Here's the error I'm getting when logging is NOT enabled (the code above
returns on the initial if condition check):

Does anyone have any ideas on what is going on?
