java - Apache camel simple http example -

i pretty new camel. have been trying fetch data http source. here's code:

from("timer://runonce?repeatcount=1")     .to("http4://webservice.com/example.xml")     .process(new structurexml())     .to("mock:resource")     .stop(); 

and:

class structurexml implements processor {      public void process(exchange httpexchange) throws exception {         string httpres = httpexchange.getin().getbody(string.class);         string[] lines = httpres.split("\n");         pattern p = pattern.compile("<map key='(.+)' value='(.+)'/>");         hashmap<string, integer> mapdata = new hashmap<string, integer>();          for(string line : lines) {             matcher m = p.matcher(line);              if(m.find())                 mapdata.put(m.group(1), integer.parseint(m.group(2)));         }          httpexchange.getin().setbody(mapdata);     } } 

well example works right want know possible ways further improve situation(e.g xml processing using xpath , etc), want know ways can store java object inside message can use in route(e.g: direct:resource instead of mock)

about java objects:

more information can found here: http://camel.apache.org/data-format.html

• jaxb
• xstream
• beanio
• jibx
• xmlbeans

these data formats useful transforming xml pojo. recomend try beanio (detailed documentation, many examples, etc).

about xpath:

it's hard tell specified without web-service response.

example:

setbody().xpath("/soap:envelope/soap:body/s:insertresponse/s:data",             xmlnamespaces.getnamespace()). 

about example:

you need set lot of properties , header (before http request), worked fine. example:

    setproperty(exchange.content_type).constant("application/soap+xml").     setproperty(exchange.content_encoding).constant("gzip").     setproperty(exchange.charset_name).constant("utf-8").     setheader(exchange.content_type).exchangeproperty(exchange.content_type). 

and don't see creating request web-service. easy of velocity (http://camel.apache.org/velocity.html), or, maybe, using soap date format (http://camel.apache.org/soap.html).

you can use jetty (http://camel.apache.org/jetty.html) instead of http4 (for me it's easier)
