Spring ws - AxiomSoapMessage & attachment with MTOM are inline

Question

Hi, im trying to understand how the AxiomSoapMessageFactory handles request (the body & attachment) but i dont understand some points (or they are maybe features)

i 'm using AxioSoapMessageFactory like this :

<bean id="messageFactory" class="org.springframework.ws.soap.axiom.AxiomSoapMessageFactory">
    <property name="payloadCaching" value="true"/>
    <property name="attachmentCaching" value="true"/>
</bean>

Here is the point :

I have thought that the AxiomSoapMessage will contain :

• the SoapMessage in the axiomMessage property like in my request
• the attachment in the attachments property.This one is stored in a temp directory thanks to (attachmentCaching=true)

But the attachment is intead inline See this screenshot

So why is the attachment inline like here ? Is what any interceptor will see ? What is the benefit of have an attachment inline if the attachmentCaching (see above) was set to true ?

I know i should ask this on the Spring forum but it seems almost death concerning answers. Thanks in advance for your help !
