Client Application for Apache Axis Web Services

[gabsaga.tata]

The following client application works fine when I pass in a state code
which returns the full state name as a string.
On the other hand, if I don't pass in any arguments, it should return a
vector of StateObj objects but this doesn't seem to be working because
I get the exception below.
There are no compile time errors or warnings.
I have also included the WSDL. Any help will be greatly appreciated.
Thanks. Gabsaga

package com.states;

import java.util.Vector;

public class StatesClient
{
public static void main(String [] args) throws Exception
{
// Make a service
com.ws.StatesService service = new com.ws.StatesServiceLocator();

// Now use the service to get a stub to the service
com.ws.States st = service.getstates();

if (args.length == 0)
{
Vector vec = new Vector();
vec = st.getAllStates();
StateObj obj = null;
String stateName = null;
String stateCode = null;

System.out.println("State Code \t\t State Name");
System.out.println("----------------------------------------");
for (int i = 0; i < vec.size(); i++)
{
obj = (StateObj)vec.elementAt(i);
stateCode = obj.getStateCode();
stateName = obj.getStateName();
System.out.println(stateCode + "\t\t" + stateName);
}
}
else
{
String stateCode = args[0];

// Make the actual call
System.out.println("State name for code " + stateCode + " = " +
st.getAState(stateCode.toUpperCase()));
}
}
}
