Spring-ws response when using split/aggregate

[wheli]

Hello,

I have a Java DSL route that takes a spring-ws request and sends a response. 

from("spring-ws:rootqname:{urn:foo}barRequest?endpointMapping=#endpointMapping")
.beanRef(BeanRef.UTILS, "blah")
.beanRef("xdsLogic", "processResponse")
.marshal(jaxbRs);

This works fine. I am now attempting to grab all the attachments from the
request, split them, process them simultaneously, aggregate the results and
then send a response. Functionally, it works, but i am no longer getting the
response back.

from("spring-ws:rootqname:{urn:foo}barRequest?endpointMapping=#endpointMapping")
.split().method(BeanRef.SOAP_ATTACHMENT_SPLITTER,
"splitMessageOnAttachments")
.beanRef(BeanRef.UTILS, "blah")
.aggregate(constant(true), new
SoapAttachmentAggregationStrategy())
.completionSize(simple("${in.header[" +
HeaderKeys.SOAP_ATTACHMENT_COUNT + "]}"))
.beanRef("xdsLogic", "processResponse")
.marshal(jaxbRs);

If i comment out the split, aggregate, and completionSize lines, the
response works again. So the splitting and aggregating is definitely
screwing something up, but I can't figure out what it is exactly.  I tried
adding "exchange.setPattern(ExchangePattern.InOut);" to the end of
"processResponse", but that doesn't seem to make any difference. 

Any ideas?

Hi,

You may need to provide the reply aggregation strategy in the split() method
itself. It should be something like below. Also i doubt that the MEP needs
to be set before splitting.

  split(new MyExpression(), new
SoapAttachmentAggregationStrategy());

I recently worked on a similar thing, and we were sending data via direct
component. We got the aggregated response back to the caller. I had used
scatter-gatherer EIP for this to work.

Thanks,
Kalyan
