After sending a test SOAP request to (compiled) "Drools Camel server example", running on JBoss7 application server, the following exception occurs:
...
java.lang.ClassCastException: org.apache.cxf.binding.soap.SoapMessage cannot be cast to java.lang.String
        at org.kie.jax.soap.PreCxfTransportSoapProcessor.process(PreCxfTransportSoapProcessor.java:36) [kie-camel-6.0.1.Final.jar:6.0.1.Final]
...

I used the following patch (hack), to make the example work:

diff --git a/kie-camel/src/main/java/org/kie/jax/soap/PreCxfTransportSoapProcessor.java b/kie-camel/src/main/java/or

         SOAPMessage soapMessage = MessageFactory.newInstance().createMessage( mimeHeaders,
                                                                               is );

It seems to me that the call to:
...
exchange.getIn().getHeaders()
...
 (apart from valid MIME headers, such as host, content-type etc ) also (wrongly?) returns the entire SOAP request object, which then cannot be typecast to string.
