Camel Restlet and CXF SOA Integration Issue - soap

Question

I am new to Camel and am facing an issue with a route I need to setup. It will be great if someone can either guide me to the correct forum or better still rectify the issue I am facing.
Here is what I need to do - expose a restlet endpoint to accept data; use this data as input to an external SOAP web service and send back the response in JSON format back to the caller...
Here is what I have done...however, I am getting the following error while Camel tries to call the Web Service...can anyone guide me here? Thanks.
I am using camel 2.11.1 and cxf-codegen-plugin version 2.7.11
I am getting the following exception: org.restlet.data.Parameter cannot be cast to java.lang.String.
public class IntegrationTest extends CamelTestSupport {
String restletURL = <url>;
#org.junit.Test
public void integTest() throws Exception {
//trying to simulate the rest service call...
template.sendBodyAndHeader(restletURL, "Body does not matter here", "data", "{\"FromCurrency\":\"AUD\",\"ToCurrency\":\"USD\"}");
}
#Override
protected RouteBuilder createRouteBuilder() throws Exception {
return new RouteBuilder() {
#Override
public void configure() throws Exception {
System.out.println("In Counfigure");
String cxfEndpoint = "cxf://http://www.webservicex.net/CurrencyConvertor.asmx?"
+ "wsdlURL=http://www.webservicex.net/CurrencyConvertor.asmx?wsdl&"
+ "serviceName={http://www.webserviceX.NET/}CurrencyConvertor&"
+ "portName={http://www.webserviceX.NET/}CurrencyConvertorSoap&"
+ "dataFormat=MESSAGE";
XmlJsonDataFormat xmlJsonFormat = new XmlJsonDataFormat();
SoapJaxbDataFormat soap = new SoapJaxbDataFormat("net.webservicex", new ServiceInterfaceStrategy(CurrencyConvertorSoap.class, true));
GsonDataFormat gson = new GsonDataFormat(ConversionRate.class);
gson.setFieldNamingPolicy(FieldNamingPolicy.UPPER_CAMEL_CASE);
from(restletURL).routeId("Restlet")
.process(new Processor() {
#Override
public void process(Exchange exchange) throws Exception {
String data = (String) URLDecoder.decode((String) exchange.getIn().getHeader("data"), "UTF-8");
System.out.println(data);
// get the mail body as a String
exchange.getIn().setBody(data);
Response.getCurrent().setStatus(Status.SUCCESS_OK);
}
})
.unmarshal(gson)
.marshal(soap)
.log("${body}")
.to(cxfEndpoint)
.unmarshal(soap)
.marshal(xmlJsonFormat);
.log("${body}");
}
};
}
}
However, the sample works when I try out the individual pieces - restlet alone and CXF alone...
Thanks,

Answer 1

Sure Willem, here is the entire configure implementation:
#Override
public void configure() throws Exception {
String restletURL = "restlet:http://localhost:8080/convert/{data}?restletMethods=get";
String cxfEndpoint = "cxf://http://www.webservicex.net/CurrencyConvertor.asmx?"
+ "portName={http://www.webserviceX.NET/}CurrencyConvertorSoap&"
+ "dataFormat=MESSAGE&loggingFeatureEnabled=true&defaultOperationName=ConversionRate&defaultOperationNamespace={http://www.webserviceX.NET/}&synchronous=true";
SoapJaxbDataFormat soap = new SoapJaxbDataFormat("net.webservicex", new ServiceInterfaceStrategy(CurrencyConvertorSoap.class, true));
soap.setVersion("1.2");
GsonDataFormat gson = new GsonDataFormat(ConversionRate.class);
gson.setFieldNamingPolicy(FieldNamingPolicy.UPPER_CAMEL_CASE);
from(restletURL).routeId("Restlet")
.process(new Processor() {
#Override
public void process(Exchange exchange) throws Exception {
String data = (String) URLDecoder.decode((String) exchange.getIn().getHeader("data"), "UTF-8");
exchange.getIn().setHeader("org.restlet.http.headers", "");
exchange.getIn().setHeader("data", "");
exchange.getIn().setBody(data);
Response.getCurrent().setStatus(Status.SUCCESS_OK);
}
})
.unmarshal(gson)
.marshal(soap)
.to(cxfEndpoint)
.unmarshal(soap)
.marshal(gson)
.process(new Processor() {
public void process(Exchange exchange) throws Exception {
String output = exchange.getIn().getBody(String.class);
exchange.getOut().setBody(output);
}
});
}

Answer 2

The issue I was facing has been resolved. In addition to "exchange.getIn().setBody(data);", I added the following line of code "exchange.getIn().setHeader("org.restlet.http.headers", "");" in order to get rid of the class cast exception I was getting. The restlet headers were causing this issue and once these headers were removed (I didn't need the headers in the first place), everything worked as expected.
Thanks,
Ritwick.
