How to invoke a simple webservice with camel? - web-services

Question

this is my route:
<route>
<from uri="timer:timerName?period=2000"/>
<to uri="ahc:http://www.google.com/search?q=Camel"/>
<log message="${property.CamelHttpResponseCode}"/>
</route>
i want to get response code status but i got this error
Exchange[Message: [Body is null]]
How can i fix this problem ?

Answer 1

I guess reading the "Get the response code" paragraph in the documentation would have helped :
Exchange exchange = template.send("ahc:http://www.google.com/search", new Processor() {
public void process(Exchange exchange) throws Exception {
exchange.getIn().setHeader(Exchange.HTTP_QUERY, constant("hl=en&q=activemq"));
}
});
Message out = exchange.getOut();
int responseCode = out.getHeader(Exchange.HTTP_RESPONSE_CODE, Integer.class);

For this simple case you can use camel-jetty. Otherwise there are additional components such as Camel-Restlet for calling and exposing HTTP services.
http://camel.apache.org/jetty.html
<route>
<from uri="direct:start"/>
<to uri="http://www.google.com/search?q=Camel"/>
<route>
Edit:
Just for testing purposes you can do like this:
<route>
<from uri="jetty://localhost:5050/test"/>
<to uri="jetty://http://www.google.com?q=Camel"/>
<route>
Then use a tool like postman in chrome or fiddler and call your localhost service.
