Camel Enrich in a Loop
Hello, I have the following use case, >From a route, I want to call a remote service A using CXF which gives me a list of data. For each data element in the list, I populate a response object, and then I again have to call service B to get addtional data to enrich this response object. Finally, I will return a collection of response objects. How should I implement this in the best way? For example, Response - Collection X f1 f2 f3 f4 Service A returns Collection I map from each element of this collection to create a new X with fields f1 and f2 populated. Then I call Service B which returns object Q with which I populate fields f3 and f4. Finally I return a collection of X What are the best patterns to realize this use case? -- View this message in context: http://camel.465427.n5.nabble.com/Camel-Enrich-in-a-Loop-tp5736543.html Sent from the Camel - Users mailing list archive at Nabble.com.

Re: Camel Enrich in a Loop
I am not sure whether a simple Splitter / Aggregator combination can help me address this. Should these be sufficient for the case that I described? -- View this message in context: http://camel.465427.n5.nabble.com/Camel-Enrich-in-a-Loop-tp5736543p5736629.html Sent from the Camel - Users mailing list archive at Nabble.com.
Re: Camel Enrich in a Loop
See also the content enricher EIP. Or use a java bean and do the calls from there and merge the replies into a response etc. You dont have to do 100% in Camel routes. You can use java code as well.
