camel http component 500

Question

i was creating cxf/camel webservice and i've created for test code like this:

@GET
@Path("/user")
@ProduceMime({ "application/json" })
public String user(@FormParam("token") String token) throws Exception {

        CamelContext context = new DefaultCamelContext();

        context.addRoutes(new RouteBuilder() {
            public void configure(){
                from("direct:start").to("http://google.com");
            }
        });

        context.start();

        return token;

    }

}

Then i've compiled it and copied do FUSE ESB deploy folder. My webservice was installed, but when i opened URL with my webservice i got 500 response:

  org.apache.cxf.interceptor.Fault: Failed to create route route17 at: >>> To[http://google.com] <<< in route: Route[[From[direct:start]] -> [To[http://google.com]]] because of Failed to resolve endpoint: http://google.com due to: No component found with scheme: http

import org.apache.camel.component.http.*;
import org.apache.camel.component.http.helper.*;

on ESB i have turned on camel-http

Answer 1

You need to install the camel-http feature. From the Fuse ESB console you can type:

features:install camel-http

And then after that you can install/start your bundle.

And as Ben says, what you are doing inside the rest service is totally wrong. You should setup Camel route once. If you want to call a http endpoint from Java code using Camel, then you do not need a route, but you can use a ProducerTemplate. See the Camel docs for more details.

Answer 2

couple of things, "No component found with scheme: http" means that you are missing the camel-http dependency in your bundle

next, you should setup your Camel context/routes once...not in a method call like this.
