choose the 1st from two(many) Search-responses
I am total newbie in Camel, but hope here I am right ...
.. The Camel looks pretty powerfull for my needs, but i don't found any
sample, than make something similar. I want perform parallely two or more
request into some search engines and get back the only dirst request. Just
like the example below have to send back the the winner from 2 searches,
where win the first finished search:
like
Input: "Camel Apache"
Process::
1) http://www.google.de/search?q=Camel+Apache
2) http://www.bing.com/search?q=Camel+Apache
Output:::
resp1!=null? {1} : {2}
Assumes the response have the similar format (xhtml for ex.) and need not to
be converted at all. Just for start the pure RAW will be ok. In another
words the looser's answer will be ignored/broken.
I just found the sample for Camel+Tomcat, but...
...really it is not so easy to make a fist step! Which EIP is it? Please
help! It should be really simple.
search
Add a search to uri, eg ?search=camel

Hi
Take a look at, see the async client API section
http://camel.apache.org/async
Its also covered in chapter 10 in the Camel book in more details.

Hi Claus,
thank you for answer. As for me it should be _VERY_ easy to make it.
Somethink like 2-lines but...
...i try to finish it already 3 (!) days. Samlples with Camel, Spring,
Xml-Scheme, MQ, e.t.c even works sometimes. But any my modification gives me
almost the same - any_kind_of_errors :( I "LOVE" spring-dynamic-weaving. So
many hops via so different levels of abstraction don't give me full
imagination how it should work. Only runtime is able to detect what is
really wrong.
Could you please kill me with your draft DSL without Spring, if it is
possible? It should be maximal 3 lines of code, am I right? Just
Implementation this on pure java is not much complex...

You can also just from a java bean send 2x async requests to an
endpoint and grab the first that completes.

I think you are looking for the http://camel.apache.org/scatter-gather.html
scatter-gather pattern. If you use the proper
http://camel.apache.org/aggregator2.html aggregation strategy
(completionSize=1, etc), this should work for you...
