Rest to Stax not working

[sonu123 <sa...@rediffmail.com>]

Hi,
I have a route which accepts a post request in plain/text format in the REST
DSL, I want to forward it to another route where I intend to parse incoming
body (XML)  using stax component.  My route look like this.

restConfiguration()
.component("servlet")
	.contextPath("Drools-Router/rest")
	.port(9090)
	.enableCORS(true)
	.bindingMode(RestBindingMode.off)

.post().consumes("text/plain")
	.type(String.class)
	.produces("text/plain")
	.outType(String.class) 
	.to("direct:multicastdemo")

from("direct:mainRoute")
.tracing().routeId("stax-parser")
      .log("Content of the body in the main route: ${body}")	
	.to("stax:com.cacib.passer.handler.UserStory1XMLSaxHandler")   
.transform().method("routingService", ,"createRoutingResponse")
.end()

I am getting this exception
/org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 0; Unexpected
EOF in prolog
 at [row,col {unknown-source}]: [1,0]/

When I am changing my first  route to keep XML Payload into  a file  and 
second route read data from the same file, then it is working as expected.  
My modified route, which is working as expected look some like this 

.post().consumes("text/plain")
.type(String.class)
	.produces("text/plain")
	.outType(String.class) 
	.to("file:target/in?fileName=abc-${date:now:yyyyMMdd}.xml")

.from("file:target/in?noop=true&delay=1000")
.tracing().routeId("stax-parser")
      .log("Content of the file in the main route: ${body}")	
	.to("stax:com.cacib.passer.handler.UserStory1XMLSaxHandler")   
	.transform().method("routingService", "createRoutingResponse")
.log("After Drools processing : ${body} ")
.end()
	.log("Done processing a  file: ${body} ");

Can you please tell me where I am doing wrong.

I had a similar problem recently with JaxRS component.

The output of the JaxRS was an instance of javax.ws.rs.core.Response.

I needed to pull the Entity out of the response and set that to my Body before doing an XML parse.

Here is the snippet I had:

Response jaxrsResponse = newExchange.getIn().getBody(Response.class);
if (jaxrsResponse != null)
	newExchange.getIn().setBody(jaxrsResponse.getEntity());

					                                                return newExchange;
