Hi,
I created one webservice in the OSGI format and installed it in the
servicemix.
The webservice worked fine and i was able to send and receive requests
through SoapUI software.
I tried to add some apache camel code inside this so that i can send a
string to a file.
The implementation is as follows
This is my webservice implementation class.
package com.webservice.calculator;
import java.util.logging.Logger;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.xml.bind.annotation.XmlSeeAlso;
import javax.xml.ws.RequestWrapper;
import javax.xml.ws.ResponseWrapper;
import org.apache.camel.CamelContext;
import org.apache.camel.Component;
import org.apache.camel.Endpoint;
import org.apache.camel.Exchange;
import org.apache.camel.Producer;
import org.apache.camel.ProducerTemplate;
import org.apache.camel.component.file.FileComponent;
import org.apache.camel.component.log.LogComponent;
import org.apache.camel.impl.DefaultCamelContext;
import com.progress.pso.payments_api.PaymentsApi;
/**

@javax.jws.WebService(
serviceName = "CalculatorService",
portName = "CalculatorSoapPort",
targetNamespace = "http://calculator.webservice.com";,
wsdlLocation =
"file:/D:/harbeer/Maven_Project/payment-web-service-osgi/src/main/resources/wsdl/Calculator.wsdl",
endpointInterface =
"com.webservice.calculator.CalculatorPortType")
public class CalculatorPortTypeImpl implements CalculatorPortType {
private static final Logger LOG =
Logger.getLogger(CalculatorPortTypeImpl.class.getName());
private PaymentsApi paymentApi;
private CamelContext camel;
private ProducerTemplate template;
public CalculatorPortTypeImpl() throws Exception {
camel = new DefaultCamelContext();
template = camel.createProducerTemplate();
camel.addComponent("file", new FileComponent());
camel.start();
}
public void setPaymentApi(PaymentsApi paymentApi) {
this.paymentApi = paymentApi;
}
/* (non-Javadoc)
* @see
com.webservice.calculator.CalculatorPortType#subtractNumbers(java.math.BigInteger
inputOne ,)java.math.BigInteger inputTwo )*
*/
public java.math.BigInteger subtractNumbers(java.math.BigInteger
inputOne,java.math.BigInteger inputTwo) {
try {
sendToCamelFile("harbeer");
return paymentApi.subtractNumbers(inputOne, inputTwo);
} catch (Exception ex) {
ex.printStackTrace();
throw new RuntimeException(ex);
}
}
private void sendToCamelFile(String name) {
try {
// get the log component
Component component = camel.getComponent("file");
Endpoint endpoint =
component.createEndpoint("file:///D:/harbeer");
Exchange exchange = endpoint.createExchange();
exchange.getIn().setBody(name);
exchange.getIn().setHeader(FileComponent.HEADER_FILE_NAME,
"harbeer.txt");
// now we want to send the exchange to this endpoint and we then
need a producer
// for this, so we create and start the producer.
Producer producer = endpoint.createProducer();
System.out.println(producer);
producer.start();
System.out.println(name);
producer.process(exchange);
producer.stop();
} catch (Exception e) {
// we ignore any exceptions and just rethrow as runtime
throw new RuntimeException(e);
}
}
}
I installed this new webservice implementation inside servicemix 4 as an
osgi bundle.
I got following exception when i called webservice method subtractNumbers();

Please help if i am missing some thing.
