Not getting response back when splitter and agreegator pattern
implemented in camel
Can you please advice on below issue I am facing while using camel for
implementing splitter/ aggregator pattern
I am using producer template to invoke the route like below
response = template.requestBody("direct:start5",req,String.class);
My route is like below
from("direct:start5").setHeader(Exchange.HTTP_METHOD,constant("GET")).setHeader(Exchange.HTTP_QUERY,
body()).split(body(String.class).tokenize("}")).process(new
SplitProcessor()).to(property).aggregate(SpliterStratergy).header(Exchange.HTTP_METHOD).ignoreInvalidCorrelationKeys().completionSize(4).to(agre);
As per this route Camel splits my request and the call goes to
SpliterStratergy for each splited part.
In this class I am aggregating the response for all splits
The final out put can be sent on the next point in the route.
How ever I am not getting the final response back on the response variable.
For any other EP I am getting data back in the response variable
Can you explain how to solve this issue.
I can solve this issue by putting the final output on mock end point and
then using consumer to read data However expectation in real life production
enviroment is to get data back from producer template's request method
Regards
Pankaj

Hi
Sounds like you need this EIP instead
http://camel.apache.org/composed-message-processor.html
And look for the splitter only example how to do that.

See that link, and the splitter only example, eg you can do fork/join
work easily.

Thanks a Lot for your time,
I have implemented this pattern and facing one issue please clarify below
After the final output is created by AgreegationStratergy class will
producer template's request body and header method will return it as
response
Or
I need to drop this output on some endpoint and retrive it by some
mechanisum.
As per your reply i should look at below link
http://camel.apache.org/composed-message-processor.html
which talks about sending output to mock end point and retriving it from
there by second route
Please confrim
