    How to invoke a rest service from Camel routes

    Jboss Beginner Newbie

      Thanks Grzegorz

      This is what i am trying to achieve

       

      1) REST UI http://localhost:9090/route/customerservice/customers/GOOG

       

      2) Calls :http://www.webservicex.net/stockquote.asmx/GetQuote?symbol=RHT   FROM camel endpoint ) But it throws error

       

      MY CONFIGURATION and class files are :

       

      1 )Call http://localhost:9090/route/customerservice/customers/GOOG from REST UI

       

      2) This invokes my Route

       

      public class CustomerServiceRoute extends RouteBuilder {

          @Override

          public void configure() throws Exception {

              getContext().setTracing(true);

              from("cxfrs://http://localhost:9090/route?resourceClasses=com.fusesource.samples.CustomerServiceResource")    

                      .to("cxfrs://http://www.webservicex.net/stockquote.asmx/GetQuote?symbol=GOOG")

                      .to("file:target/goog");

          }

      }

       

       

      Class CustomerServiceResource

       

      @Path("/customerservice/")

      public class CustomerServiceResource {

          @Context

          private UriInfo uriInfo;

       

          public CustomerServiceResource() {

          }

          @GET

          @Path("/customers/{id}/")

          @Produces("text/xml")

          public Customer getCustomer(@PathParam("id") String id) {

              return null;

          }

       

      }

       

      CAMEL.XML

       

      <cxf:rsServer id="rsServer" address="http://localhost:9090/route"

                        serviceClass="com.fusesource.samples.CustomerServiceResource"/>

          <bean id="customerServProcessor" class="com.fusesource.samples.CustomerServiceProcessor"/>

       

          <bean id="routeBuilder" class="com.fusesource.samples.CustomerServiceRoute"/>

          <camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">

              <routeBuilder ref="routeBuilder"/>

          </camelContext>
