How do i control my soap foult back to the client ?

here is some of my route:

from("cxf:bean:hubws?dataFormat=MESSAGE").streamCaching()
.onException(Exception.class).process(new LogError("")).end()
.bean(AddIpBean.class)
.bean(SetRoutingKey.class)
.bean(Util.class, "setMiljo")
.multicast()
.to("direct:channel1", "direct:channel2","direct:channel3")
.aggregationStrategy(new HubAggregationStrategy())
.stopOnException();

from("direct:channel1")
.onException(Exception.class).process(new LogError("MQFAIL")).end()
.setHeader(HubConstants.LOGSTATE.getValue(),
constant(HubConstants.MQSTART.getValue()))
.bean(Mq.class, "mqHeaders")
.bean(Mq.class, "logStart")
.choice()
.when(header(HubConstants.MILJO.getValue()).contains("U"))
.inOnly("activemqU:topic:HUB_TOP01")
.when(header(HubConstants.MILJO.getValue()).contains("T"))
.inOnly("activemqT:topic:HUB_TOP01")
.when(header(HubConstants.MILJO.getValue()).contains("S"))
.inOnly("activemqS:topic:HUB_TOP01")
.when(header(HubConstants.MILJO.getValue()).contains("P"))
.inOnly("activemqP:topic:HUB_TOP01");

I have create an error so the ("activemqU:topic:HUB_TOP01") throws an
exception, the MQ i down.

.onException i go to LogError class, and what i want to get back to the
client is a soapfoult only with the message "MQFAIL"

But how...

I trien tryed to do some code that change the exchange:

exchange.setException(null);

Message out = exchange.getOut();
out.setBody("MQFAIL");
out.setHeader(org.apache.cxf.message.Message.RESPONSE_CODE, new
Integer(500));

but the client get this message back:

Sequential processing failed for number 0. Exchange[Message: MQFAIL].
