xfire 窄接口方式实现的客户端、偶尔报错，请指教

11097082 2014-02-18 09:48:23
服务器端也是用XFIRE写的，客户端端利用窄接口的方式进行实现，测试通过，但是运行起来，偶尔会报错，并且如果这个客户端运行的频率越高报错的几率及越大，请大大帮忙。



  String serviceUrl = "http://127.0.0.1:8080/ws/services/TestModelService";

			

		

	   Service serviceModel = new ObjectServiceFactory().create(ITestModelService.class, null,

			   serviceUrl , null);

		

	   XFireProxyFactory serviceFactory = new XFireProxyFactory();

	   TestModel tm=new TestModel();

	   tm.setId(111);

	   tm.setMobile("133333333");

	   tm.setName("zzzzzzzzzzzz");

	   try {

		  ITestModelService tws=(ITestModelService)serviceFactory.create(serviceModel, serviceUrl);

		

		  String rs=tws.addModel(tm);

		  System.out.println(rs);

		  

		  TestModel tm1=tws.getModel();

		  

		  System.out.println(tm1.getName());

		  

		

	   } catch (MalformedURLException e) {

		// TODO Auto-generated catch block

		  e.printStackTrace();

	   }


这个代码可以运行，但是当5秒运行一次，就会报错：
org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: Fault: java.lang.NullPointerException

有时甚至会出现SOKET没有关闭的情况。

大概每6小时左右还会出现这样的一个错误：

引用 10 楼 11097082 的回复:
对的，因为我使用一天timer定时通过WEBSERVICE上报信息，通常是可以的，但是有时候会报错； 而且有时发现链接服务端被拒绝，好像服务端的WEBSERVICE被关闭一样，但是通过HTTP是可以登录到服务平台。
对于服务端的WEBSERVICE类似宕机情况，只有重启TOMCAT才能 解决。我平台的系统是SSH2

也许是服务端的问题，服务端返回的soap报文不合法引起客户端readMessage出现异常,检查下服务端日志 或者直接wireshark类软件监控此端口的http消息，检查出问题时的请求/应答报文内容

我测试代码、准备用作设备状态上报的，计划通过定时器每5秒执行一次，大部分时候运行正确的，但是就是偶尔会报错，我是奇怪好好可以运行的程序，没理由会出现空指针啊

空指针还不好去debug吗？ 还有你的代码哪里每五秒执行一次了？
