EJB 调用webservice问题

我企图让EJB中的Sessionbean 能使用CallStockData这个类来调用Web 服务 
在部署之前 已单独测试过CallStockData类能成功调用Web服务
在部署完测试Remote接口的时候 抛出如下异常 小弟已困惑数日 在线求高手相助package stockserver;import org.apache.axis.*;
import org.apache.axis.client.*;
import org.apache.axis.client.Service;
import java.net.URL;
import javax.xml.rpc.ParameterMode;
import org.apache.axis.client.Call;public   class CallStockData{
     public static String [] GetStockDataByType(String type){
         try {
             Service service = new Service();
             Call call = (Call) service.createCall();             call.setTargetEndpointAddress(new URL(
                     "http://localhost:7001/Stock-Service/XMJJ")); //服务地址(wsdl描述地址)
             call.setOperationName("GetStockData"); //调用服务函数             call.addParameter("string", org.apache.axis.Constants.XSD_STRING,
                               ParameterMode.IN); //参数类型说明             call.setReturnClass(String[].class); //返回类型说明            return (String[]) call.invoke(new Object[] {type}); //得到返回的结果
         } catch (Exception e) {
             System.out.println("Call WebService Error : " + e.toString());
             return null;
         }      }}java.lang.NoClassDefFoundError: org/apache/axis/client/Service
