I am trying to create a folder in Alfresco using Mule ESB and Alfresco WS.

I am getting an error complaining about it a MIME issue. the flows is as below:

<flow name="MuleProxyFlowWS" doc:name="MuleProxyFlowWS">
    <http:inbound-endpoint exchange-pattern="request-response"
        host="localhost" port="8088" path="createCase" doc:name="HTTP" />

        service="com.alfresco.cmis.ws.ObjectService" doc:name="SOAP"
        enableMuleSoapHeaders="false" mtomEnabled="true"

Set Content-Type property before calling jaxws:client like:

 <set-property propertyName="Content-Type" value="whatever it is" />

For xml, it is application/xml
