Calling Web service from Java Concurrent Program

Question

Hi,
I created a Java concurrent program and created executable. Here is my code.
    public void runProgram(CpContext ctx) {
        String value = "Java Concurrent Program Testing";
        Hello hell = new Hello();
        String returnValue = hell.testURL(value);
        if(returnValue.equalsIgnoreCase("TRUE")){
            ctx.getLogFile().writeln("-- Java Concurrent Program Testing --", 0);
            ctx.getOutFile().writeln("-- Java Concurrent Program Testing --");
            ctx.getReqCompletion().setCompletion(ReqCompletion.NORMAL, "");
        else{
            ctx.getLogFile().writeln("-- Hello World! --", 0);
            ctx.getOutFile().writeln("-- Hello World! --");
            ctx.getReqCompletion().setCompletion(ReqCompletion.NORMAL, "");
    }testURL() call the web service and get the response. but when I am selecting View Output option I am always geting out put as
-- Hello World! --I tested the logic of calling web service. It giving me out put "true". Here is my Web service calling code
    public String testURL(String Value){
        HttpURLConnection httpConn = null;
        ByteArrayOutputStream bout = null;
        String setWebServiceURLResponse = "";
        String responseString="";
        String outputString = "";
        try{
            httpConn = getHttpConnection();
            bout = new ByteArrayOutputStream();
            String xmlInput = soapBodyStart +
            "<ns1:getTestURL>\n" +
            "            <ns1:URL>"+Value+"</ns1:URL>\n" +
            "        </ns1:getTestURL>"+
            soapBodyEnd;
            byte[] buffer = new byte[xmlInput.length()];
            buffer = xmlInput.getBytes();
            bout.write(buffer);
            byte[] b = bout.toByteArray();
            httpConn = setHttpConnectionRequest(b,httpConn);
            //Read the response.
            InputStreamReader isr = new InputStreamReader(httpConn.getInputStream());
            BufferedReader in = new BufferedReader(isr);
            //Write the SOAP message response to a String.
            while ((responseString = in.readLine()) != null) {
                outputString = outputString + responseString;
            //Parse the String output to a org.w3c.dom.Document and be able to reach every node with the org.w3c.dom API.
            Document document = parseXmlFile(outputString);
            String formattedSOAPResponse = formatXML(outputString);
            System.out.println("Formatted response = \n" +formattedSOAPResponse);
            //NodeList nodes = document.getElementsByTagName("setWebServiceURLResponse");
            //NodeList nodes = document.getElementsByTagName("getTestURLResponse");
             NodeList nodes = document.getElementsByTagName("ns0:getTestURLResponse");
            int len = nodes.getLength();
            System.out.println("Inside testURL Node Lenght  = "+ len);
            for(int s=0; s<nodes.getLength() ; s++){
                Node authenticateResultNode = nodes.item(s);
                if(authenticateResultNode.getNodeType() == Node.ELEMENT_NODE){
                    Element authenticateResultElement = (Element)authenticateResultNode;
                    //NodeList authenticateResultValueNode = authenticateResultElement.getElementsByTagName("ns0:return");
                    //NodeList authenticateResultValueNode = authenticateResultElement.getElementsByTagName("return");
                     NodeList authenticateResultValueNode = authenticateResultElement.getElementsByTagName("ns0:return");
                    Element authenticateResultValue = (Element)authenticateResultValueNode.item(0);
                    NodeList textFNList = authenticateResultValue.getChildNodes();
                    //System.out.println("Authenticate Result : " + ((Node)textFNList.item(0)).getNodeValue().trim());
                     setWebServiceURLResponse = ((Node)textFNList.item(0)).getNodeValue();
                     //System.out.println("Authenticate Response in getAuthenticate method : " + authenticateresponse);
                }//end of if clause
            }//end of for loop with s var
            System.out.println("Inside setWebServcieURLToFile response = " + setWebServiceURLResponse);
        catch(Exception e){
            e.printStackTrace();
        return setWebServiceURLResponse;
    }Where I am going wrong ?

sample code:
static string url = "http://my.webservice.url"; ---------------> The actual web service URL
Call = new Call(url); --------------------------------------------------> The call object used by JAX-RPC
Object[] params = new Object[]{param1, param2};---------> build the call parameters
Boolean/Integer/Whatever result = call.invoke("method name", params);------>call the invoke method to get the result
