Error using call.invoke

[Susan G. Conger]

I have a web service that has been deployed on an axis server.  The
deploy.wsdd is below:

<deployment xmlns="http://xml.apache.org/axis/wsdd/";
            xmlns:java="http://xml.apache.org/axis/wsdd/providers/java";>

 <service name="CookBooks" provider="java:RPC">
  <namespace>http://books</namespace>
  <parameter name="className" value="books.Books"/>
  <parameter name="allowedMethods" value="addBook listBooks"/>
  <parameter name="scope" value="Session"/>
     <operation name="addBook" qname="operNS:addBook"
xmlns:operNS="http://books"; >
       <parameter name="in" type="tns:BooksInfo" xmlns:tns="http://books"/>
     </operation>
     
     <operation name="listBooks" qname="operNS:listBooks"
xmlns:operNS="http://books"; returnQName="listBooksReturn"
returnType="rtns:ArrayOf_tns1_BooksInfo"
xmlns:rtns="http://localhost:8084/axis/services/CookBooks"; >
     </operation>

     <typeMapping
       xmlns:ns="http://localhost:8084/axis/services/CookBooks";
       qname="ns:ArrayOf_tns1_BooksInfo" 
       type="java:books.BooksInfo[]"
       serializer="org.apache.axis.encoding.ser.ArraySerializerFactory"
       deserializer="org.apache.axis.encoding.ser.ArrayDeserializerFactory"
       encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
     />
     <typeMapping
       xmlns:ns="http://books";
       qname="ns:BooksInfo"
       type="java:books.BooksInfo"
       serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
       deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
       encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
     />

 </service>
</deployment>

When I run the following code I get an java.lang.InstantiationException:
books.Books

public class TestClient {
    
    public static void main(String [] args) {
        try {
            String endpoint =
"http://localhost:8084/axis/services/CookBooks";;  
            Service service = new Service();
            Call call = (Call) service.createCall();
  
            call.setTargetEndpointAddress (new java.net.URL(endpoint));
            call.setOperationName (new QName
("http://soapinterop.org/CookBooks";, 
                                   "listBooks"));
            BooksInfo[] bs = (BooksInfo[])call.invoke( new Object[] {} );
// List out the cook books
            System.out.println ("List of available COOK BOOKS");
            System.out.println ("============================");
        System.out.println ("");
        System.out.println ("");
        
        } catch (Exception e) {
            System.err.println(e.toString());
        }
    }


Anyone got any ideas?

Thanks,
Susan
