WSDP and AXIS

[Serghei Jelauc]

Hi javers.
I have deployed a small servise (for examle) which is simply returns the String, using AXIS. But I tryed to create a client using WSDP from SUN. It doesn't work. Here is example:
Service:

package echo;
public class EchoMessage
{
public String getEcho(String msg)
{
return msg+" returned";
}
}

deploy.wsdd :

<deployment xmlns="http://xml.apache.org/axis/wsdd/"
            xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
 <service name="EchoService" provider="java:RPC">
  <requestFlow>
      <handler type="soapmonitor"/>
  </requestFlow>
  <responseFlow>
      <handler type="soapmonitor"/>
  </responseFlow>

  <parameter name="className" value="echo.EchoMessage"/>
  <parameter name="allowedMethods" value="getEcho getNumber"/>
 </service>
</deployment>

Client:

 
package soap;
import java.net.*;
import java.util.*;
import javax.xml.soap.*;
public class Request
{
  public static void main(String[] args)
  {
    try
    {
      SOAPConnectionFactory scFactory = SOAPConnectionFactory.newInstance();
      SOAPConnection con = scFactory.createConnection();
      MessageFactory factory = MessageFactory.newInstance();
      SOAPMessage message = factory.createMessage();
      SOAPPart soapPart = message.getSOAPPart();
      SOAPEnvelope envelope = soapPart.getEnvelope();
      SOAPHeader header = envelope.getHeader();
      SOAPBody body = envelope.getBody();
      header.detachNode();
      Name bodyName = envelope.createName("getEcho", "", "http://localhost:8080/axis/services");
      SOAPBodyElement gltp = body.addBodyElement(bodyName);
      Name name = envelope.createName("arg0");
      SOAPElement messageElement = gltp.addChildElement(name);
      messageElement.addTextNode("Test message");
      URL endPoint = new URL("http://localhost:8080/axis/services/EchoService");
      SOAPMessage response = con.call(message, endPoint);
      con.close();
      SOAPPart sp = response.getSOAPPart();
      SOAPEnvelope se = sp.getEnvelope();
      SOAPBody sb = se.getBody();
      Iterator it = sb.getChildElements();
      SOAPBodyElement bodyElement = (SOAPBodyElement)it.next();
      String echo = bodyElement.getValue();
      System.out.println("Returned echo is: "+echo);
    }
    catch(Exception e)
    {
      System.out.println("Exception: "+e.getMessage());
    }
  }
}

When I try to execute client the output message is "Exception: null"
I looked at soapmonitor and both SOAP Request and SOAP Response look normal - two absolutly normal SOAP messages.
Where is ERROR?
Thanks in advance.

I suggest you get the stack trace so you can see which statement throws the exception:

catch(Exception e)
    {
      System.out.println("Exception: "+e.getMessage());
      e.printStackTrace( System.out );
    }
