cast of returning object to vector doesn't work

[Martina Brose]

Hi, I tryed to make a web service using the wsdl2java tool (Axis beta1).
First everything went fine. I was able to compile the code, to deploy the
the service and to invoke the service using my client application. I got no
problems sending Strings, Vectors etc. and recieving Strings or Booleans.
The only problem is recieving a Vector.
The ServiceImplementation methode that should return the vector is:

public Vector getVal(String key) throws java.rmi.RemoteException,
beepingSoap.sessionXmpl.WrongKeyException {
      if(logedUsers.containsKey(key)==true)
      {
         Vector valueList = new
Vector(((User)logedUsers.get(key)).getList());
         return valueList;
      }
      else
      {
         throw new WrongKeyException("Illegal Session Key");
      }
}

The corresponding part of the SoapBindingStub is:

public java.util.Vector getVal(java.lang.String in0) throws
java.rmi.RemoteException, beepingSoap.sessionXmpl.WrongKeyException{
    if (super.cachedEndpoint == null) {
        throw new org.apache.axis.NoEndPointException();
    }
    org.apache.axis.client.Call call = getCall();
    javax.xml.rpc.namespace.QName p0QName = new
javax.xml.rpc.namespace.QName("", "in0");
    call.addParameter(p0QName, new
javax.xml.rpc.namespace.QName("http://schemas.xmlsoap.org/soap/encoding/";,
"string"), javax.xml.rpc.ParameterMode.PARAM_MODE_IN);
    call.setReturnType(new
javax.xml.rpc.namespace.QName("http://xml.apache.org/xml-soap";, "Vector"));
    call.setUseSOAPAction(true);
    call.setSOAPActionURI("");
    call.setOperationStyle("rpc");
    call.setOperationName(new
javax.xml.rpc.namespace.QName("urn:sessionXmpl", "getVal"));

    Object resp = call.invoke(new Object[] {in0});

    if (resp instanceof java.rmi.RemoteException) {
        throw (java.rmi.RemoteException)resp;
    }
    else {
        return (java.util.Vector) resp;    // This is line 180 !!!
    }
}

But when I try to invoke the getVal Methode by:
    ServiceAppService service = new ServiceAppServiceLocator();
    ServiceApp port = service.getServiceApp();
    Vector valueList = new Vector(port.getVal(key));
I get the following error message:

java.lang.ClassCastException: [Ljava.lang.Object;

So why can't the object returned to the stub be casted to a vector? I even
tryed to cast it to a String, in case the returned object was a fault
message, but I got the same exception.
Can you help me?
