中文XML论坛--webservice客户端访问异常

客户端调用的代码是
public Call testGetAttachment() {
  try {
   Service service = new Service();
   Call call = (Call) service.createCall();
   call.setTargetEndpointAddress(new java.net.URL(url));

// 设定调用的方法名
call.setOperation("getAttachment");

   call.addParameter("docId",
     org.apache.axis.encoding.XMLType.XSD_LONG,
     ParameterMode.IN);

   QName qn = new QName("urn:Attachment", "Attachment");
   call.registerTypeMapping(Attachment.class, qn, BeanSerializerFactory.class, BeanDeserializerFactory.class);
   call.setReturnClass(Attachment.class);
   //call.setReturnType(Contants, javaType)
   //call.setReturnType(org.apache.axis.encoding.XMLType.MIME_DATA_HANDLER);
   long docId = 11111;
   Object[] argsa = { docId};
   Attachment att =(Attachment) call.invoke(argsa);


   System.out.println("att:"+att.getDocType());
   byte[] b = att.getFileContent();
   saveFile(b,"aaa.pdf");

  } catch (Exception e) {
   e.printStackTrace();
  }
  return null;
}
