axis java.lang.reflect.InvocationTargetException异常

Question

我用的是tomcat5.0+asix1.4+weblogic8.1
deploy.wsdd文件:
  <service name="UsecarrequestAction" provider="java:RPC">
    <parameter name="className" value="com.bossy.traffic.webService.UsecarrequestAction"/>
    <parameter name="allowedMethods" value="nQueryUseCarRequest"/>
    <operation   name="nQueryUseCarRequest"   returnType="ns:Response"/>   
    <typeMapping deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
      encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
      qname="ns:Response"
      serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
      type="java:java.util.ArrayList"
      xmlns:ns="bean.service.ws.zcjl.com"/>
  </service>
服务端:返回List
public List nQueryUseCarRequest()
{
 List list = null;
try
{
String rl_id = "6";
if(rl_id.equals("6"))
         {                 
String dp_id="10010106111716180168";
String dTime = "";
Usecarrequest uc = new Usecarrequest();
    JdbcDao dao=uc.nQueryUserCarRequest(dTime,dp_id);
    list = dao.getListfromResultSet();
         }
}
catch(Exception e)
{
e.printStackTrace();
}
return list;
}
客户端:  Object obj = null;
    Call call;
try {
call = (Call) service.createCall();
call.setTargetEndpointAddress(new java.net.URL("http://192.168.2.170:7001/services/UsecarrequestAction") );
 call.setOperationName("nQueryUseCarRequest");
 obj = (Object) call.invoke(new Object[] {} );异常代码
