Testing Adapter Module in NWDS

Question

hi,
I have got a code for adapter module,I wanted to test it standalone using NWDS.
class XML2EdifactBean
public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData)
          throws ModuleException { //Some Code... }
I am getting some error while executing the adapter module ,so I want to call the function using main method.Can you provide me with a sample code for this.
regards,
Ujjwal Kumar.

This would be too complex to do all necessary steps for a stand alone test.
I recommend to split the generic adapter module stuff and the part, you really want to do something.
For the adapter modul, which we used on Teched session:
GetHostName.java code for 3.0/7.0
I did following: I introduced a helper class and passed the DOM code
public class HelperClass {
     String hostElementName = "host";
     String hostName = "host";
    public static void main(String[] args) {
        try {
            InputStream in = new FileInputStream(new File("in.xml"));
            OutputStream out = new FileOutputStream(new File("out.xml"));
            new HelperClass().execute(in, out);
        } catch (Exception e) {
            e.printStackTrace();
    public void setHostElementName(String hostElementName){
         this.hostElementName = hostElementName;
    public void setHostName(String hostName){
         this.hostName = hostName;
    public void execute(InputStream in, OutputStream out){
         try  {
              DocumentBuilderFactory factory;
        factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        Document document = builder.parse(in);
        Element rootNode = document.getDocumentElement();
        if(rootNode != null)  {
            Element childElement =
            document.createElement(hostElementName);
            childElement.appendChild(document.createTextNode(hostName));
            rootNode.appendChild(childElement);
        // Transforming the DOM object to Stream object.
        TransformerFactory tfactory = TransformerFactory.newInstance();
        Transformer transformer = tfactory.newTransformer();
        Source src = new DOMSource(document);
        Result dest = new StreamResult(out);
        transformer.transform(src,dest);
         } catch(Exception e){}
in the bean class, I used the helper class:
     XMLPayload xmlpayload = msg.getDocument();
            InputStream in = xmlpayload.getInputStream();
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            HelperClass hc = new HelperClass();
            hc.setHostElementName(hostElementName);
            hc.setHostName(hostName);
            hc.execute(in,out);
            byte[] docContent = out.toByteArray();
            if(docContent != null)  {
                xmlpayload.setContent(docContent);
                inputModuleData.setPrincipalData(msg);
Now I can test the parser in the NWDI
