out of memory error using axiomsoapmessagefactory and jaxb2marshaller

[drellim]

My jaxb2marshaller has mtomEnabled=true

I have declared messagefactory

<bean id="CSmessageFactory" class="org.springframework.ws.soap.axiom.AxiomSoapMessageFactory">
        <property name="payloadCaching" value="false"/>
</bean>

I refer to this in my gateway definition
<property name="messageFactory" ref="CSmessageFactory"/>

my web service extends WebServiceGatewaySupport and calls
getWebServiceTemplate().marshalSendAndReceive(requ est);

my endpoint extends AbstractMarshallingPayloadEndpoint and overrides invokeInternal

I am trying to upload a large xml file

I get the following error

The schema defines the xml as base 64 encoded

Can anyone suggest what I am doing wrong, please?

Thanks

I removed all reference to the schema, and now the stack trace is
