apache camel - call an external web service

I would like to send an http post to an external web service that I need to call.

<from uri="cxfrs://http://localhost:9876?resourceClasses=MyResource"/>
            <log message="Received. " loggingLevel="INFO" logName="MyLogger"/>
            <setHeader headerName="CamelHttpMethod">
                 <constant>POST</constant>
            </setHeader>
            <setHeader headerName="Content-Type">
                <constant>application/json</constant>
            </setHeader>
            <setBody>
                <simple>param1=param1value&amp;param2=param2value</simple>
            </setBody>
<to uri="http://samplesample.com?bridgeEndpoint=true" />
<log message="body is ${body}" loggingLevel="INFO" logName="MyLogger"/>

I'm getting an exception:

Caused by: org.apache.camel.component.http.HttpOperationFailedException: HTTP operation failed invoking http://samplesample.com with statusCode: 400

It works fine when I launch a request using rest client. Any help will be appreciated.

Instead of putting your request parameters to the message body you should set the appropriate headers, e.g. for adding HTTP querying parameters use

<setHeader headerName="CamelHttpQuery">
 <constant>param1=param1value&amp;param2=param2value</constant>
</setHeader>

or for adding HTTP path parameters use

<setHeader headerName="CamelHttpPath">
 <constant>/param1/20</constant>
</setHeader>

camel-cxfrs consumer will turn the REST request into a method call, so the camel-http producer may not interpreter the message rightly.

If you want to proxy REST request by using camel, you can just use camel-jetty component to do that.

from("jetty://http://localhost:9876?matchOnUriPrefix=true")
                    .to("http://samplesample.com?throwExceptionOnFailure=false&bridgeEndpoint=true");
