---------------------------------
Summary: LoggingInInterceptor throws when pretty printing MTOM
messages
Key: CXF-4475
URL: https://issues.apache.org/jira/browse/CXF-4475
Project: CXF
Issue Type: Bug
Components: Core
Affects Versions: 2.6.1
Reporter: aaron pieper
Priority: Minor
I'm using CXF to implement some SOAP web services. I've added a
LoggingInInterceptor to my interceptor chain through an XML configuration file
so that incoming SOAP messages will be logged. My configuration file looks like
this:
--------------------
<jaxws:endpoint id="foo" implementor="#fooServiceImpl" address="/FOO">
<!-- snip... -->
<jaxws:inInterceptors>
<ref bean="loggingInInterceptor"/>
<!-- snip... -->
</jaxws:endpoint>
<bean id="loggingInInterceptor"
class="org.apache.cxf.interceptor.LoggingInInterceptor">
<property name="prettyLogging" value="true"/>
</bean>
--------------------
This logging setup works OK for non-MTOM messages. But when an incoming message
uses MTOM, I get an error:
--------------------
org.xml.sax.SAXParseException: Content is not allowed in prolog.
at net.sf.saxon.event.Sender.sendSAXSource(Sender.java:425)

at
org.apache.cxf.interceptor.LoggingInInterceptor.logging(LoggingInInterceptor.java:152)
--------------------
The pretty-printing logic in AbstractLoggingInterceptor requires the message to
be well-formed XML, but MTOM messages have various non-XML headers and
boundaries. The "content not allowed in prolog" comes from
AbstractLoggingInterceptor trying to parse one of these boundaries as XML.
I've been able to work around this problem by disabling pretty printing.
