Creating a Web service

Question

Hi,
I have a web dynpro application that can access an external database via EJB. I also have a web module (JSP). In the web dynpro application there is a button that calls a webpage from my web module. 
Supposedly, when I click the button, the values in webpage will be taken from my external database (e.g. the text values of my webpage will come from my database).
I have been told to create a web service using my EJB and have to import that web service to my web module using a java class. Can someone point me to a tutorial on how to do this?

Hi mlsaldua,
please check this code
public class WsClnt2 {
     static final String userid = "test";
     static final String password = "init2you";
     static String soapRequestMsg = "<ns1:MaterialGetDetail
xmlns:ns1='urn:sap-com:document:sap:soap:functions:mc-style'><Material>R-1111</Material><Plant>1200</Plant><Valuationarea>1200</Valuationarea></ns1:MaterialGetDetail>"
     static class TheAuthenticator extends Authenticator {
     public PasswordAuthentication getPasswordAuthentication() {
           return (new PasswordAuthentication(userid,
password.toCharArray()));
     public static void main(String[] args) {
            try{
                   String url =
http://host:port/sap/bc/srt/rfc/sap/ZWS_MATERIAL_DETAIL?sap-client=800
                       Authenticator.setDefault(new TheAuthenticator());
                       MessageFactory msgf = MessageFactory.newInstance();
                       SOAPMessage msg = msgf.createMessage();
                       SOAPBody body =
msg.getSOAPPart().getEnvelope().getBody();
                       DocumentBuilderFactory dbf =
DocumentBuilderFactory.newInstance();
                       dbf.setNamespaceAware(true);
                       DocumentBuilder db = dbf.newDocumentBuilder();
                       ByteArrayInputStream bis=new
ByteArrayInputStream(soapRequestMsg.getBytes());
                       org.w3c.dom.Document doc = db.parse(bis);
                       body.addDocument(doc);
                       SOAPConnection connection  =
SOAPConnectionFactory.newInstance().createConnection();
                   SOAPMessage reply = connection.call(msg, url);
               reply.writeTo(System.out);
                 } catch (Exception e) {
                       // TODO Auto-generated catch block
                       e.printStackTrace();
