Using Eclipse to create a web service, Axis Exception

[Chris Stabler]

hi all,

i am using Eclipse Galileo to create w WSDL from a simple java piece of code. i am using Axis/Tomcat 6.0. File name is Converter.java

 package wtp;

public class Converter
{
  public float celsiusToFarenheit ( float celsius )
  {
    return (celsius * 9 / 5) + 32;
  }

  public float farenheitToCelsius ( float farenheit )
  {
    return (farenheit - 32) * 5 / 9;
  }
}
   

once the WSDL is created, everything looks fine. now i need to create the client which i do from eclipse.

I get the following java files in my Converter/src now in my project:

ConverterProxy
ConverterService
ConverterServiceLocator
ConverterSoapBindingStub

i now want to write a simple client to retrieve information if i passed in a Celsius or F value.

  package wtp;

import java.rmi.RemoteException;

import org.apache.axis.*;


import wtp.ConverterSoapBindingStub;
import wtp.ConverterServiceLocator;


public class ConverterClient {

        public static void main(String[] args) {
                try {
                        float celsiusValue = 100;
                        ConverterSoapBindingStub stub = new ConverterSoapBindingStub();

                    
                        System.out.println("Celsius : " + celsiusValue + " = " + "Farenheit : " + stub.celsiusToFarenheit(celsiusValue));
                } catch (AxisFault e) {
                        e.printStackTrace();
                } catch (RemoteException e) {
                        e.printStackTrace();
                }

        }
}  

i get no errors but when i run the client i get the following error messages:

AxisFault
faultCode: {http://xml.apache.org/axis/}Server.NoEndpoint
faultSubcode:
faultString: No endpoint
faultActor:
faultNode:
faultDetail:
{http://xml.apache.org/axis/}exceptionNamerg.apache.axis.NoEndPointException
{http://xml.apache.org/axis/}stackTrace:No endpoint

at wtp.ConverterClient.main(ConverterClient.java:26)

No endpoint
at wtp.ConverterSoapBindingStub.celsiusToFarenheit(ConverterSoapBindingStub.java:103)
at wtp.ConverterClient.main(ConverterClient.java:26)

I am totally new to web services and have no idea what i am doing. just trying something in the dark. If anyone could offer some help it would be appreciated.

I also noticed that my Converter.java file with the actual code has been changed to:

 /**
 * Converter.java
 *
 * This file was auto-generated from WSDL
 * by the Apache Axis 1.4 Apr 22, 2006 (06:55:48 PDT) WSDL2Java emitter.
 */

package wtp;

public interface Converter extends java.rmi.Remote {
    public float celsiusToFarenheit(float celsius) throws java.rmi.RemoteException;
    public float farenheitToCelsius(float farenheit) throws java.rmi.RemoteException;
}   

So i am trying to figure out how it is going to know what functionality is in each of those functions now. Sorry for the noob questions. thanks much in advance.

i noticed that that Stub constructor actually needs a URL and a Service so it can gather an endpoint for the service.

 public ConverterSoapBindingStub(java.net.URL endpointURL, javax.xml.rpc.Service service) throws org.apache.axis.AxisFault {
         this(service);
         super.cachedEndpoint = endpointURL;
    }  

i was able to change the code to get the URL, which is just, "http://localhost:8080/Converter/services/Converter" but i find no where to actually get the service so i am stuck for now.

Updated Code:

   package wtp;

import java.rmi.RemoteException;

import javax.xml.rpc.ServiceException;

import org.apache.axis.*;


import wtp.ConverterSoapBindingStub;


public class ConverterClient {
	
		

        public static void main(String[] args) throws ServiceException {
        	
        	String loc;
    		Converter conv;
    		
                try {
                        float celsiusValue = 100;

                        ConverterServiceLocator locator = new ConverterServiceLocator();
                        loc = locator.getConverterAddress();
                        conv = locator.getConverter(); //doesnt return a service
                       // ConverterSoapBindingStub stub = new ConverterSoapBindingStub(loc, ???);
              
                        System.out.println("Celsius : " + celsiusValue + " = " + "Farenheit : " + stub.celsiusToFarenheit(celsiusValue));
                } catch (AxisFault e) {
                        e.printStackTrace();
                } catch (RemoteException e) {
                        e.printStackTrace();
                }

        }
}

Could any one solve this problem because I also have the same problem.

Thanks

Please help,

I have the same problem. When I create a web service client using WTP, I get a package with following files:
MyService_BindingStub.java
MyService_PortType.java
MyService_Service.java
MyService_ServiceLocator.java
MyService_Proxy.java

And?

OK, I generate a class and try to combine my calls like above. What ever I try I end up with the “NoEndPointException”.

Please tell me how to write the WSClient.

Thanks

Ron

should you be using the proxy to actually communicate w/the web service rather than the stub? the proxy will have all the wsdl endpoint information in it already......

[sahil nanda]

hi,
service locator creates the endpoint and also execute the actual implementation of web service i.e. the stub will be called from service locator.
service locator actually implements the service which you have created.


do this in your main method.

ConverterServiceLocator testService = new ConverterServiceLocator();
float fah = testService.celsiusToFarenheit (98.4);
System.out.println(fah);


this code should work....
