> As described in the documentation you can use [camel-cxfrs as producer|https://github.com/apache/camel/blob/39c0d63d923bfe9236834ecb1c4470bb7e9e7eaa/components/camel-cxf/src/main/docs/cxfrs-component.adoc#how-to-configure-the-rest-endpoint-in-camel]. You have some approaches like using a proxy created from a interface which maps all the services available in the targeted REST web service (sample [here|https://github.com/willianantunes/honesto-sqn/blob/d4bf48257fc64a4725894c7f07c24bb1a516d410/src/main/java/br/com/willianantunes/serenata/JarbasAPI.java#L14]). As I'm using Spring Boot and Apache Camel I may create a bean through XML or programmatically.
> h4. Creating the test sample
> I'm testing with the following:
> [https://gist.github.com/willianantunes/58979bfb91ee30c7ff4e235940e60880]
> You can find a copy of JarbasAPI [here|https://github.com/willianantunes/honesto-sqn/blob/d4bf48257fc64a4725894c7f07c24bb1a516d410/src/main/java/br/com/willianantunes/serenata/JarbasAPI.java#L14].
> h4. When rsClient producer works as expected
> When I do using the first approach using the configuration below everything works fine:
> {code:xml}
> <?xml version="1.0" encoding="UTF-8"?>
> <beans xmlns="http://www.springframework.org/schema/beans"
>        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

>                   serviceClass="br.com.willianantunes.serenata.JarbasAPI"/>
> </beans>

>         SpringJAXRSClientFactoryBean clientFactoryBean = new SpringJAXRSClientFactoryBean();

>         clientFactoryBean.setServiceClass(JarbasAPI.class);
>         return clientFactoryBean;
>     }

> Although it has no difference compared to XML, it does not work.
> h4. When does it fail?
> Debugging you can see the following:
>  * The bean is correctly got [here|https://github.com/apache/camel/blob/a4cfea6823d31eacf57489ffffe1ffeead9a256b/components/camel-cxf/src/main/java/org/apache/camel/component/cxf/jaxrs/CxfRsComponent.java#L76] is CxfRsComponent.
>  * When a message is sent and there is a _to_ command with the URI *cxfrs:bean:serviceEndpoint,* I see the message arriving [here|https://github.com/apache/camel/blob/a4cfea6823d31eacf57489ffffe1ffeead9a256b/components/camel-cxf/src/main/java/org/apache/camel/component/cxf/jaxrs/CxfRsProducer.java#L94] in CxfRsProducer.
>  * The method [invokeProxyClient|https://github.com/apache/camel/blob/a4cfea6823d31eacf57489ffffe1ffeead9a256b/components/camel-cxf/src/main/java/org/apache/camel/component/cxf/jaxrs/CxfRsProducer.java#L103] is called.
>  * The SpringJAXRSClientFactoryBean which I provided as bean is ignored. A new one is created [here|https://github.com/apache/camel/blob/834a59910e4b6b8d089e229b39f6c8673e7c3f9a/components/camel-cxf/src/main/java/org/apache/camel/component/cxf/jaxrs/CxfRsEndpoint.java#L414] and when it arrives to the next line the method invoked is from [CxfRsSpringEndpoint|https://github.com/apache/camel/blob/834a59910e4b6b8d089e229b39f6c8673e7c3f9a/components/camel-cxf/src/main/java/org/apache/camel/component/cxf/jaxrs/CxfRsSpringEndpoint.java] which uses [configurer.ConfigureBean|https://github.com/apache/camel/blob/834a59910e4b6b8d089e229b39f6c8673e7c3f9a/components/camel-cxf/src/main/java/org/apache/camel/component/cxf/jaxrs/CxfRsSpringEndpoint.java#L77] that only works with XML.
> h4. Versions used
>  * Spring Boot: 1.5.12.RELEASE
>  * Apache Camel: 2.21.1
> h4. Proposal to make it works
> The idea obviously is to make both approaches work, maybe merging the configuration or as long as the user is providing a custom SpringJAXRSClientFactoryBean then making it the standard instead of creating a new one for each request as it is available in the CxfRsSpringEndpoint from the start.
