Camel for Rest Service
Hi,
I am new to Apache camel and trying to Configure camel for invoking a rest
webservice and getting a response in JSON and type cast it. I tried the
following but, am not able to get the response anywhere.
Had the configuration file "camel-context.xml" as
------------------------------------------
<cxf:rsClient id="signOnRsClient"
address="http://158.151.224.44:8080/organizations?match&CountryISOAlpha2Code=GB&CustomerReferenceText=REFTEXT&DUNSNumber=210021531"
/>
<route streamCache="true">
<from uri="direct:cafe" />
<log message="****************Sign ON Request Fired************" />
<bean ref="signOnRequestHandler" />
<to uri="cxfrs://bean://signOnRsClient"/>
<bean ref="signOnResponseHandler" />
------------------------------------------
In signOnRequestHandler, I had the following lines for appending the request
parameters
------------------------------------------
public void process(Exchange exchange) throws Exception {
@SuppressWarnings("unchecked")
Message inputMessage = exchange.getIn();
inputMessage.setHeader("x-dnb-user", "uatuser1");
inputMessage.setHeader("x-dnb-pwd", "password-1");
}
------------------------------------------
I had main java file , where am trying to invoke the from:uri for initiating
the rest action as below
------------------------------------------
public static void main(String[] args) throws Exception {
AbstractApplicationContext applicationContext;
ProducerTemplate template;
applicationContext = new
ClassPathXmlApplicationContext("camelcontext.xml");
CamelContext camelContext =
applicationContext.getBean("camelContext", CamelContext.class);
template = camelContext.createProducerTemplate();
template.sendBody("direct:cafe", ExchangePattern.InOut);
}
------------------------------------------
In the response, am not able to figure out on how to process it. The
response handler is as below
------------------------------------------
public void process(Exchange exchange) throws Exception {
System.out.println("--->" + exchange.getOut().getHeaders().toString());
System.out.println("--->" + exchange.getOut());
------------------------------------------
I might have done something wrong in the above things, which am unaware.
Please guide me on how to resolve this.
Thanks, Bala

Not sure, but I think you should try something like this :
(InputStream) is = exchange.getIn().getBody();
Read the byte array into a string and then convert jsonstring to your
object.

I am getting the InOut in the response. If you look at my example closely, I am sending InOut using the below line
template.sendBody("direct:cafe", ExchangePattern.InOut);
And, this is wat am getting in the response and not the actual JSON Object. My Response handler code is as below.
System.out.println("--->" + exchange.getIn().getHeaders().toString());
System.out.println("--->" + exchange.getIn().getBody());
Thanks

What's invocation looks like, you should get a Response object from the message body.
If you are using camel-cxfrs you will not see the under layer response (XML or JSON).

Sorry, I Can't understand your reply. Can you please be more specific.
If you look at what am trying, I try to use the Configuration file for
invoking a uri and from the configuration file, am trying to call a rest
service, from which am getting the response in JSON which am trying to read.
Please help.
Thanks, Bala

After upgrade to CXF 2.7.1 it will be possible to do
Response response = ...
MyType myType = response.readEntity(MyType.class);
At the moment, one can also register a ResponseReader client side
provider, it's no longer available in CXF 2.7.x but can help with
casting 'response.getEntity()' in JAX-RS 1.1 to a specific type, see
http://cxf.apache.org/docs/jax-rs-client-api.html#JAX-RSClientAPI-Limitations
Finally, I guess the conversion should work with a proxy-based cxfrs
client...
Cheers, Sergey

Hi Willem
Thanks for the response. Am able to get the response, after I changed the code. In the body "exchange.getIn().getBody()", I don't get anything. Can you please let me know on how do I get a JSON response ? Am not able to get a good material for this in internet too.
Thanks in advance

If you are using the processor to handle the response message you need to take the in message instead of take the out message.
As Camel Pipeline will copy the out message of previous exchange to the next exchange in message.

If you are using the processor to handle the response message you need to take the in message instead of take the out message.
As Camel Pipeline will copy the out message of previous exchange to the next exchange in message.
