Returning an Array over Axis

I have a very nice Axis Web Service running in which I call a "query" function which returns an arbitrarily sized array of type String[].

I call the axis implementation file with the following call (Assume all setup of service is correct):

java.lang.String[] yes_list = (java.lang.String[])handler.query(groupName, password, accountName, conditions);

handler.query is the function which returns the String[]. Regardless, this function, while actually successfully running through Axis, brings about the following exception on the local machine:

java.lang.ClassCastException
java.lang.ClassCastException
at $Proxy0.query(Unknown Source)
at _2._0._0._127.axis.services.adminHandlerServicePort.adminHandlerClient2.main(adminHandler
Client2.java:77)

I have checked the mailing list for possible causes but to know avail. Would somebody be kind enough to offer some advice as to how I could stop this message from coming up?

Below is my client program:

package placeholder.axis.services.clientHandlerServicePort;

public class clientHandlerClient2
{
static String url = "http://placeholder/axis/services/clientHandlerServicePort";
static String router = "http://placeholder/axis/clientDirect";

static String service = "clientDirectService.wsdl";

    public static void main(String[] args)
    {
       try
       {
    System.err.println("This Client tests getReport");

    ServiceFactory sf = ServiceFactory.newInstance();
           URL u = new URL(router + "/" + service);
           QName serviceName = new QName(url,"clientHandlerService");
           Service s = sf.createService(u,serviceName);

QName portName = new QName(url,"clientHandlerServicePort");

           List handlerChain = s.getHandlerRegistry().getHandlerChain(portName);
           HandlerInfo hi = new HandlerInfo(LoggingHandler.class,null,null);
           handlerChain.add(hi);

           //Checking for proper syntax of call
           if (args.length!=3)
    {
            System.err.println("Incorrect usage of Client. Please use the following:");
System.err.println("clientHandlerClient" + " [Account Name]" + "   [Password]" + "   [Conditions]");
           }
           else
       {
                System.out.println("Thank You. Processing. . .");
  ClientHandler handler = (ClientHandler) s.getPort(portName, ClientHandler.class);

  String accountName   = args[0];
                String password    = args[1];
                String conditions = args[2];

  if(s == null)
             System.out.println("Service Not Working Properly");

String[] queryList = handler.query(accountName, password, conditions);

System.out.println("Testing in csv format");
String format = "csv";

String[] rawQueryList = handler.getQuery(accountName, password, queryList, format);

  System.out.println("Finished.");
    }
        }
catch(Exception e)
{
  System.err.println("Error running Client:");
  System.err.println(e);
  e.printStackTrace();
}
    }

}

I would appreciate any comments on this manner. I have checked the axis-mailing list for previous solutions however have found none have been helpful for me to diagnose.

Sincere Thanks,

James Crosson
