Hi,

I still receive an error:

clientaxis\Battle\OrderB.java:322: PrettyElementToStream(org.w3c.dom.Element,jav
a.io.OutputStream) in org.apache.axis.utils.XMLUtils cannot be applied to (org.w
3c.dom.Element,java.io.StringWriter)
      XMLUtils.PrettyElementToStream(result, w);
              ^
1 error

Thank you for your time.

here is some of the code relavant to this issue: perhaps you could understand what I am exactly doing:

package clientaxis.Battle;
import java.util.Vector;
import java.util.Set;
import java.util.HashSet;
import java.util.Collections;
import java.util.Iterator;
import java.io.StringWriter;

import javax.xml.parsers.DocumentBuilder;

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.message.SOAPEnvelope;
import org.apache.axis.message.SOAPBodyElement;
import org.apache.axis.utils.XMLUtils;

import org.w3c.dom.Document;

//import com.wrox.jws.stockcore.StockCore;

public class OrderB {

... some code goes here...

public String getBattleService(String[] uniqb) throws Exception {
   //final String methodName = "OrderB.main";
     StringWriter w = new StringWriter();
    try {

      // We need a namespace-aware parser
      documentBuilderFactory = DocumentBuilderFactory.newInstance();
      documentBuilderFactory.setNamespaceAware(true);
      parser = documentBuilderFactory.newDocumentBuilder();

      // We create the document for the request (the XML document that will
      // be embedded inside the SOAP body).
      Document document = parser.newDocument();

      // The <portfolio/> element is the root of our document;
      Element requestElement = document.createElementNS(nameSpaceURI,
       orderbattleTag);
     // Element command        = document.createElement(args[0]);
    Element command        = document.createElement(uniqb[0]);
      requestElement.appendChild(command);

      for(int index = 1; index < uniqb.length; index++) {
        Element ticker = document.createElement(tickerTag);

  (Element)requestElement.cloneNode(true));
      } else {

    // server. You might need to replace the following URL with what is
        // suitable for your environment
        String endpointURL =

        Service service     = new Service();
        Call    call        = (Call)service.createCall();

        // Create a SOAP envelope to wrap the newly formed document

        SOAPBodyElement requestBody     =
     new SOAPBodyElement(requestElement);
        requestEnvelope.addBodyElement(requestBody);

        // Set the endpoint URL (address we are talking to) and method name
        call.setTargetEndpointAddress(new URL(endpointURL));
        call.setSOAPActionURI(orderbattleTag); // method name = tag name

        // Submit the document to the remote server
        SOAPEnvelope responseEnvelope = call.invoke(requestEnvelope);

        // Get the <orderbattle/> element from the response
        SOAPBodyElement responseBody =
          (SOAPBodyElement)responseEnvelope.getBodyElements().get(0);
        result = responseBody.getAsDOM();
      }

      XMLUtils.PrettyElementToStream(result, w);
      return w.toString();

        } catch (Exception exception) {
         throw exception;
    }
}
