couldnt call one webservice from other webservice getting not an interface error and IllegalArgumentException at runtime

**yash_java** · September 2nd, 2014, 07:34 AM

Task :
I have to a develop client which access a webservice (which in turn will communicate with another dummy webservice) to give back the response to the client.

What I have developed so far :

I have developed a client and two webservices.

My Code :

dummy webservice
- a webservice which will give a hard coded response

package groups.yashey;
 
import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.xml.soap.SOAPMessage;
 
@WebService
public interface SendFaxResponseInterface {
 
  @WebMethod
  public void sendFaxResponse();
}
 
package groups.yashey;
 
 
import javax.jws.WebService;
import javax.jws.WebMethod;
import java.io.FileOutputStream;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPHeaderElement;
import javax.xml.soap.SOAPBody;
import javax.xml.soap.SOAPBodyElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPHeader;
import javax.xml.soap.SOAPMessage;
import javax.xml.soap.SOAPPart;
 
 
@WebService
public class SendFaxResponseWebService implements SendFaxResponseInterface {
  @WebMethod
  public void sendFaxResponse() {
  MessageFactory factory = null;
  SOAPMessage soapMsg = null;
  SOAPPart part = null;
  SOAPEnvelope envelope = null;
  SOAPHeader header = null;
  SOAPBody body = null;
  SOAPHeaderElement headerElement = null;
  SOAPBodyElement element = null;
  SOAPBodyElement soapElement1 = null;
  SOAPBodyElement soapElement2 = null;
  SOAPBodyElement soapChildElementOfSoapElement2 = null;
  SOAPBodyElement soapSecondChildElementOfSoapElement2  = null;
  UserDetailsBean userBeanObj = new UserDetailsBean();
  userBeanObj.setUsername("admin");
  userBeanObj.setPassword("admin");
 
 
  if(  userBeanObj.getUsername().equals("admin") && userBeanObj.getPassword().equals("admin") ) {
  try{
  factory = MessageFactory.newInstance();
  soapMsg = factory.createMessage();
  part = soapMsg.getSOAPPart();
  envelope = part.getEnvelope();
  header = envelope.getHeader();
  body = envelope.getBody();
 
 
  headerElement = header.addHeaderElement(envelope.createName("Response","","http://ws.easylink.com/RequestResponse/2011/01"));
  headerElement.addChildElement("SenderKey").addTextNode("http://xoa.xpedite.com/JobSubmit");
  headerElement.addChildElement("RequestID").addTextNode("BNP_TEST_JOB14");
  headerElement.addChildElement("ProcessingID").addTextNode("0ACD321E-1163-130724184717275");
 
 
  element = body.addBodyElement(envelope.createName("jobSubmitResult","","http://ws.easylink.com/JobSubmit/2011/01"));
 
 
  soapElement1 = (SOAPBodyElement) element.addChildElement("Status");
  soapElement1.addChildElement("StatusCode").addTextNode("0");
  soapElement1.addChildElement("SubmissionTime").addTextNode("2013-07-24T18:47:17.275Z");
  soapElement1.addChildElement("CompletionTime").addTextNode("2013-07-24T18:47:18.180Z");
  element.addChildElement("SubmitId").addTextNode("BNPTest1");
 
 
 
 
  soapElement2 = (SOAPBodyElement) element.addChildElement("MessageResult");
  soapElement2.addChildElement("MessageId").addTextNode("BNP_TEST1_MSG14");
 
 
  soapChildElementOfSoapElement2 = (SOAPBodyElement) soapElement2.addChildElement("Status");
  soapChildElementOfSoapElement2.addChildElement("StatusCode").addTextNode("0");
  soapChildElementOfSoapElement2.addChildElement("StatusMessage").addTextNode("OK");
  soapChildElementOfSoapElement2.addChildElement("SubmissionTime").addTextNode("2013-07-24T18:47:17.338Z");
  soapChildElementOfSoapElement2.addChildElement("CompletionTime").addTextNode("2013-07-24T18:47:18.180Z");
 
 
  soapSecondChildElementOfSoapElement2 = (SOAPBodyElement) soapElement2.addChildElement("JobId");
  soapSecondChildElementOfSoapElement2.addChildElement("XDN").addTextNode("flusme");
  soapSecondChildElementOfSoapElement2.addChildElement("MRN").addTextNode("1130365");
 
 
  // writing the soap message to console
  //soapMsg.writeTo(System.out);
 
 
 
 
  // writing the soap message to file
  soapMsg.writeTo(new FileOutputStream("NewSoapMessage.xml"));
  System.out.println("Soap message written to the file");
 
 
  }catch(Exception e){
    e.printStackTrace();
       }
     }
  }
}

another Webservice
- this is responsible to access the dummy webservice on the client request

package groups.yashey;
 
import javax.jws.WebService;
import javax.jws.WebMethod;
 
@WebService
public interface SendFaxClientWSInterface {
 
  @WebMethod
  public void sendFax();
}
 
package groups.yashey;
 
import javax.jws.WebService;
import javax.jws.WebMethod;
 
@WebService
public class SendFaxClientWS implements SendFaxClientWSInterface {
 
  @WebMethod
  public void sendFax() {
  new SendFaxResponseWebServiceService(). getSendFaxResponseWebServicePort().sendFaxResponse();
  }
}

client
- a stand alone program to call the webservice.

import groups.yashey.*;
public class SendFaxWebServiceClient {
  public static void main(String...ar) {
     new SendFaxClientWSService().getSendFaxClientWSPort().sendFax();
  }
}

extra helper classes

- this class helps to get the data to the webservice

package groups.yashey;
 
 
public class UserDetailsBean {
  private String username;
  private String password;
 
  public UserDetailsBean() {
  System.out.println("UserDetailsBean Object is Created");
  }
 
  public String getUsername() {
  return username;
  }
 
  public void setUsername(String username) {
  this.username = username;
  }
 
  public String getPassword() {
  return password;
  }
 
  public void setPassword(String password) {
  this.password = password;
  }
}

- these classes are used to publish the webservices

package groups.yashey;
import groups.yashey.SendFaxResponseInterface;
import groups.yashey.SendFaxResponseWebService;
import groups.yashey.SendFaxClientWSInterface;
import groups.yashey.SendFaxClientWS;
 
import javax.xml.ws.Endpoint;
 
public class PublishWebService1 {
  public static void main(String...ar) {
 
  SendFaxResponseInterface sendFaxWebService = new SendFaxResponseWebService();
  //SendFaxClientWSInterface sendFaxWebServiceClient = new SendFaxClientWS();
 
  Endpoint.publish("http://localhost:7770/sendFaxWebService", sendFaxWebService);
  //Endpoint.publish("http://localhost:7771/sendFaxWebServiceClient", sendFaxWebServiceClient);
 
  System.out.println("SendFax webservice is ready...");
  //System.out.println("SendFax webservice client is also ready...");
 
  }
}
 
package groups.yashey;
import groups.yashey.SendFaxResponseInterface;
import groups.yashey.SendFaxResponseWebService;
import groups.yashey.SendFaxClientWSInterface;
import groups.yashey.SendFaxClientWS;
 
import javax.xml.ws.Endpoint;
 
 
public class PublishWebService2 {
  public static void main(String...ar) {
 
  SendFaxClientWSInterface sendFaxWebServiceClient = new SendFaxClientWS();
  Endpoint.publish("http://localhost:7771/sendFaxWebServiceClient", sendFaxWebServiceClient);
 
  //System.out.println("SendFax webservice is ready...");
  System.out.println("SendFax webservice client is also ready...");
  }
}

Errors Iam getting :

- both are run time errors
- one is saying my service is not an interface
- other one throwing IllegalArgumentException at my dummy web service
