> I am calling an endpoint using cxfrs client with the http api. So I have 
> something like that in the DSL : 
> .... 
> .setHeader(CxfConstants.CAMEL_CXF_RS_USING_HTTP_API, constant(true)) 
> .setHeader(Exchange.HTTP_PATH, simple("/endpoint/${header.myHeader}")) 
> .setHeader(Exchange.HTTP_METHOD, constant(POST)) 
> .to("cxfrs:bean:myClient") 
> .... 
> This usually works fine. 
> I had a somewhat nasty error when someone did a copy paste of my server, 
> with the variable substitution style (something like /endpoint/{myVariable}) 
> at that point, ${header.myHeader} resolved to {myVariable}, thus the url the 
> client will try to resolve is  /endpoint/{myVariable}. When trying to parse 
> this URL, CXF will not be happy, since there is no value to replace what it 
> thinks to be a variable, and will throw an IllegalArgumentException with 
> message Unresolved variables; only 0 value(s) given for 1 unique 
> variable(s). 
> After looking a bit in the code, I understood better what happens. 
> In order to avoid that, it would be nice to use the mechanism of CXF to 
> replace variables in URI. 
> In the DSL, we would have something like : 
> .... 
> .setHeader(CxfConstants.CAMEL_CXF_RS_USING_HTTP_API, constant(true)) 
> .setHeader(CxfConstants.CAMEL_CXF_RS_VAR_VALUES, 
> simple("[${header.myHeader}]")) 
> .setHeader(Exchange.HTTP_PATH, constant("/endpoint/{myVariable}")) 
> .setHeader(Exchange.HTTP_METHOD, constant("POST")) 
> .to("cxfrs:bean:myClient") 
> ....
