Help! Cannot invoke operation on web service!

I am at a total loss. I am probably doing something obviously wrong and stupid but I've been staring at this for two days and can't see straight anymore.

I implemented a web service in JBoss 4.0.1 SP1 as a POJO with a method "String getDocuments(String userid, String password)". The web service seems to deploy just fine and I can use the URL?wsdl command to see my WSDL but my test client cannot seem to invoke this method. I get an AxisFault saying there is no such method. My code, WSDL and exception is below. Any and all suggestions are greatly appreciated!

The code of interest in my test servlet is:

private String callWebServiceForGetDocuments(String userid, String passwd) throws Exception {
    //
    // Get the url
    //
    String urlString = "http://localhost:8080/MyApp/MyWS?wsdl";
    if (urlString == null || urlString.length() == 0) {
      throw new Exception("URL is not set.  See your system administrator.");
    }
    URL url = new URL(urlString);    
    //
    // Get a handle to the service call
    //
    String wsNamespace = "http://webservice.company.com/";
    String wsName = "MyService";
    String wsPort = "MyWSPort";
    String wsOperation = "getDocuments";
    QName qname = new QName(wsNamespace, wsName);
    QName port = new QName(wsNamespace, wsPort);
    QName operation = new QName(wsNamespace, wsOperation);
    ServiceFactory factory = ServiceFactory.newInstance();
    Service service = factory.createService(url, qname);
    for (Call c : service.getCalls(port)) {
      log.error("OPERATION ON SERVICE: " + c.getOperationName());      
    }
    Call call = service.createCall(port, operation);
    //
    // Call the web service
    //
    log.info("making web service call: wsNamespace=" + wsNamespace + " wsName=" + wsName + " wsPort=" + wsPort + " wsOp=" + wsOperation);
    return (String)call.invoke(new Object[] {userid, passwd});    
  }

The exception is thrown by call.invoke(). As you can see, I loop over the calls provided by the web service and "getDocuments" is in the list so I am assuming I am seeing the web service.

The exception is:

I figured this out. For everyone else's benefit, for whatever reason, JBoss 4.0.1 does not like web services being deployed in an expanded state. When we deployed our WAR file that contained the web service in a .war file (vs. in an expanded .war directory), everything worked.
