xfire框架的web service无法实现大文件下载并报错

[Jason-Jiao]

我使用xfire框架做的一个web service通过使用DataHandler代理的方式实现大文件下载，且客户端可以调用服务端的接口并且有log输出，但是无返回值，并报如下错误：

最终无法实现文件下载的功能。

客户端代码如下：
实现代码如下：
String otaServiceUrl = "http://10.0.0.53:8080/NeoCloudService/services/NeoOtaService";
Service otaServiceModel = new ObjectServiceFactory().create(INeoOtaService.class, null,
"http://10.0.0.53:8080/NeoCloudService/services/NeoCloudService?wsdl", null);
XFireProxyFactory serviceFactory = new XFireProxyFactory();
try {
INeoOtaService otaService = (INeoOtaService) serviceFactory.create(otaServiceModel, otaServiceUrl);
Client fileClient = Client.getInstance(otaService);
fileClient.setProperty("mtom-enabled", "true");
fileClient.setProperty(HttpTransport.CHUNKING_ENABLED, "true");
String fileName = "NeoCloudService.war";
File downloadFile = new File("/home/jiao/log", fileName);
DataHandler downloaddh = otaService.downloadFile(fileName);
System.out.println(downloaddh.getName());
try {
downloadFile.createNewFile();
InputStream in = downloaddh.getInputStream();
FileOutputStream out = new FileOutputStream(downloadFile);
byte[] buff = new byte[2014 * 1024];
int len = -1;
while(-1 != (len=in.read(buff, 0, buff.length))){
out.write(buff, 0, len);
}
in.close();
out.flush();
out.close();
System.out.println("down over");
} catch (IOException e) {
e.printStackTrace();
}


} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

服务端代码如下：
public interface INeoOtaService {

public String uploadFile(DataHandler dh, String fileName);

public DataHandler downloadFile(String fileName);

public String searchVersionInfo();

public String updateVersionInfo();

public String addVersionInfo();

public String deleteVersionInfo();

public String sendBroadcast();
}

public class NeoOtaService implements INeoOtaService{

@Override
public DataHandler downloadFile(String fileName) {
File file = new File(ServiceProperties.getOtaUpgradeFileUrl(), fileName);
System.out.println(file.length());
DataHandler dh = new DataHandler(new FileDataSource(file));
System.out.println(dh.getName());
return dh;
}
｝

配置文件内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xfire.codehaus.org/config/1.0"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"

System.out.println(file.length()); System.out.println(dh.getName()); 这两句输出在服务端可以正常打出。
