求助！java调用webservicejava.net.SocketException: Unexpected end of file from server

[coolboy8816]

java调用.net开发的webservice报错，服务端有返回，但是java客户端收到返回值为null：
代码如下：
String soapAction = nameSpace+DownloadOrUpload;

// 指定WebService的命名空间和调用的方法名
SoapObject so = new SoapObject(nameSpace, DownloadOrUpload);
//设置参数
so.addProperty("ip",prop[0]);
//
if(!"GetWaitInspectionList".equals(DownloadOrUpload)){
so.addProperty("ticketCode",prop[1]);
}

SoapSerializationEnvelope envelope = null;
if(anchemode.equals("1")){
envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12);
}else{
envelope = new SoapSerializationEnvelope(SoapEnvelope.VER10);
}


envelope.bodyOut = so;
envelope.dotNet = true;
//
envelope.setOutputSoapObject(so);
HttpTransportSE transport = null;
try {
transport = new HttpTransportSE(endPoint,30000);

transport.reset();
int i = 0;
while(i<2){
try {

transport.call(soapAction, envelope);
i ++;
} catch (Exception e) {
e.printStackTrace();
i++;
}
}
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}


String strout = "101";
SoapObject object = null;
Object result = "";
try {
object = (SoapObject) envelope.bodyIn;
if(object==null){
log.info("联网返回为null");
return "";
}

} catch (Exception e) {
e.printStackTrace();
log.info("联网异常:"+e.getMessage());
}

try {
result = object.getProperty(0);
} catch (Exception e) {
e.printStackTrace();
log.info("数据异常:"+e.getMessage());
}
String gStr=result.toString();

报错：

求助大神支持，谢谢

应该是网络不稳定造成的，客户端做异常处理，然后重发。

网络没问题的，我重复发也不行，用VC做测试程序就可以正常接收到返回。
