How can I call a web service with no parameters via a
producerTemplate?
Hi,
I have to call a web service with an operation that maps to:
public java.lang.String ping();
When I try to call it using a productTemplate I keep getting:
Get the wrong parameter size to invoke the out service, Expect size 0, Parameter size 1. Please check if the message body matches the CXFEndpoint POJO Dataformat request.
I've tried calling with a null body and without specifying a body at all, but it still generates the same error.
Is there any way I can call this operation?
Thanks
Jim

You set a wrong url, please remove the option of dataFormat=MESSAGE because
you just invocation the web service with a string instead of SOAP message
output stream.

Dear William,
Actually Web method contains single argument, so I have passed
"Hello"(*exchange.getIn().setBody("Hello"); *). Can u tell me what is the
problem of bellow code.
*Web Service Method:*
public String getApplication(String data) {
System.out.println("getApplication");
return "GetApplication Method Call :";
}
*Calling Code.*
static CamelContext context;
public static void main(String args[]) throws Exception {
CamelContext context = new DefaultCamelContext();
ProducerTemplate template =
context.createProducerTemplate(0);
context.start();
String url =
"cxf://http://localhost:8081/buzzor-service/services/ApplicationService?"
+
"wsdlURL=http://localhost:8081/buzzor-service/services/ApplicationService?wsdl&"
+
"serviceName={http://service.application.buzzor.atpl.com}ApplicationService&"
+
"portName={http://service.application.buzzor.atpl.com}ApplicationServiceHttpPort&"
+ "dataFormat=MESSAGE";
Exchange reply = sendSimpleMessage(template, url);
org.apache.camel.Message out = reply.getOut();
String result = out.getBody(String.class);
System.out.println(reply);
Thread.sleep(10000);
context.stop();
}
private static Exchange sendSimpleMessage(ProducerTemplate template,
String endpointUri) {
Exchange exchange = template.request(endpointUri, new
Processor() {
public void process(final Exchange exchange) {
exchange.getIn().setBody("Hello");
exchange.getIn().setHeader(CxfConstants.OPERATION_NAME,
"getApplication");
exchange.getIn().setHeader(CxfConstants.OPERATION_NAMESPACE,
"http://service.application.buzzor.atpl.com");
exchange.getIn().setHeader(Exchange.FILE_NAME, "testFile");
exchange.getIn().setHeader("requestObject",
new DefaultCxfBinding());
}
});
return exchange;
}
*After Executing this code. no error thrown by this code but web service
also not called.
in result variable Bellow Message has been received
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"

As you set the invocation parameter as POJO list, you need to set the dataFormate to be POJO.
Because camel-cxf default data format is POJO, removing the endpointUri option of dataFormat should work for you.

Done Required changes still have some issue.
String endpointUri=

Exchange exchange = template.request(endpointUri, new Processor() {
public void process(final Exchange exchange) {
List<String> oList = new ArrayList<String>();
oList.add("Hello");
exchange.getIn().setBody(oList);
exchange.getIn().setHeader(CxfConstants.OPERATION_NAME,
"getApplication");
exchange.getIn().setHeader(CxfConstants.OPERATION_NAMESPACE,

exchange.getIn().setHeader(Exchange.FILE_NAME, "testFile");
exchange.getIn().setHeader("requestObject",

SOAPMessage message = processSOAP(exchange);
System.out.println(message);

Please use exchange.getIn() instead of exchange.getOut() in the process method.

Dear,
I also want to call third party web service using camel but i am unable to
call.
I have tried two things
First is:Creating SOAP String manually.
Exchange exchange = template.request(endpointUri, new Processor() {
public void process(final Exchange exchange) throws Exception {
exchange.getIn()
.setBody(
"<soap:Envelope
xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"
+ "<soap:Body><ns1:getApplication
xmlns:ns1=\"http://service.application.buzzor.atpl.com\">"
+ "<arg0
xmlns=\"http://service.application.buzzor.atpl.com\">hello world</arg0>"
+ "</ns1:getApplication></soap:Body></soap:Envelope>");
}
});
return exchange;
This code will call Web Service but instead of creating manually string when
i have tried bellow code for calling web service it will give an error
String url =
"cxf://http://localhost:8081/buzzor-service/services/ApplicationService?"
+
"wsdlURL=http://localhost:8081/buzzor-service/services/ApplicationService?wsdl&"
+
"serviceName={http://service.application.buzzor.atpl.com}ApplicationService&"
+
"portName={http://service.application.buzzor.atpl.com}ApplicationServiceHttpPort&"
+ "dataFormat=MESSAGE";
Exchange exchange = template.request(url, new Processor() {
public void process(final Exchange exchange) {
exchange.getOut().setBody("Hello");
exchange.getOut().setHeader(CxfConstants.OPERATION_NAME,
"getApplication");
exchange.getOut().setHeader(CxfConstants.OPERATION_NAMESPACE,
"http://service.application.buzzor.atpl.com");
exchange.getOut().setHeader(Exchange.FILE_NAME, "testFile");
exchange.getOut().setHeader("requestObject",
new DefaultCxfBinding());
}
});
return exchange;
*Exception is "org.apache.camel.InvalidPayloadException: No body available
of type: java.io.InputStream on: Message: [Body is null]. Caused by: No type
converter available to convert from type: null to the required type:
java.io.InputStream with value null. Exchange[Message: Hello]. Caused by:

java.io.InputStream with value null]"*
Can any one help me to resolved my problem.
Thanks in Advance.

Thank you Willem, that works.
My call is now:
return template.requestBodyAndHeaders( this.groupsUri,
new Object[0], headers, String.class );
and I get the expected response.
The "ping" operation is just a test one, but now it means I can make my
test use much more of my main code.
Thanks again.

Can you try to set the message with new object array with a length 0 ?
Like this
exchange.getIn().setBody(new Object[0]).

Hi,
Can you post a snippet of the call you are making with the producerTemplate,
WSDL document and the exact error you get...
Thanks,
