Hi, thanks for making it work;
You might want to reuse (CXF) JAXRSUtils.**getStructuredParams(query,
"&"),

this will return JAX-RS MultivaluedMap which will hold list values, and
will take care of parameters having multiple values (&a=1&a=2, etc).

I'm still not sure how it can be resolved with Simple Binding Style, but I
think I can manage to do a patch, unless Raul (Simple Binding Style guru)
can beat me to it :-)

Cheers. Sergey

Thanks a lot for helping out and the heads-up.

Yes, you are right.  I could get the query portion alone using:

String query = exchange.getIn().getHeader(**Exchange.HTTP_QUERY,
String.class);

Taking up from your hint, I am doing the following and my flow looks
complete :

***Interface ***
      @GET
      @Path("search")
      @Produces(MediaType.**APPLICATION_JSON)
      public String searchGet();


***Implementation - Target method***

public SearchResult<WikiSearchHit> wikiGet(Exchange exchange){
          String q = exchange.getIn().getHeader("q"**, String.class);
          String size = exchange.getIn().getHeader("**size",
String.class);
          String start = exchange.getIn().getHeader("**start",
String.class);


***Router***
public class RestToBeanRouter extends RouteBuilder {

      @Override
      public void configure() throws Exception {

          from("cxfrs://bean://rsServer?**bindingStyle=SimpleConsumer")
                  .process(new ParameterProcessor())
                  .removeHeaders("CamelHttp*")
                  .multicast()
                  .parallelProcessing()
                  .aggregationStrategy(new CoreSearchResponseAggregator()*
*)
                  .beanRef("**searchRestServiceImpl", "wikiGet")
                  ....
                  .end()
                  .marshal().json(JsonLibrary.**Jackson);
          //.to("log://camelLogger?**level=TRACE");

      }


      class ParameterProcessor implements Processor {
          @Override
          public void process(Exchange exchange) throws Exception {

              Map<String, String> stringStringMap =
convertQueryStringAsMap(**exchange.getIn().getHeader(**
Exchange.HTTP_QUERY,
String.class));

              //System.out.println("**stringStringMap = " +
stringStringMap);

              for (Map.Entry<String, String> eachParamEntry :
stringStringMap.entrySet()) {
                  exchange.getIn().setHeader(**eachParamEntry.getKey(),
eachParamEntry.getValue());
              }
          }


          private Map<String,String> convertQueryStringAsMap(String
queryString){

              return
Splitter.on("&").**omitEmptyStrings().**trimResults().**
withKeyValueSeparator("=").**split(queryString);

          }

      }
}


Thanks a ton !!!
