> --------------------------------------------------------------------
>
> Key: CAMEL-12541
> URL: https://issues.apache.org/jira/browse/CAMEL-12541
> Project: Camel
> Issue Type: Bug
> Components: camel-cxfrs
> Affects Versions: 2.21.1
> Reporter: Willian Antunes
> Priority: Major
>
> 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";

> </beans>
> {code}
> h4. When rsClient producer does not work as expected
> XML works fine, but when I do the same thing programmatically it doesn't.
> {code:java}
> @Bean("serviceEndpoint")
> public SpringJAXRSClientFactoryBean serviceEndpoint() {
> SpringJAXRSClientFactoryBean clientFactoryBean = new
> SpringJAXRSClientFactoryBean();

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

> {code}
> 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

> 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.
