webservice传输大文件

server端：(根据需求写)

? 接口：

public interface MyFile {
	 public DataHandler downFile(String type,String id);
	 
}

public class MyFileImpl implements MyFile {

	public DataHandler downFile(String fileName,String id) {
		Properties p = new Properties();
		String path=id+".xml";
		File file = null;
		try {
			p.load(MyFileImpl.class.getResourceAsStream("/parameter.properties"));
		} catch (IOException e) {
			e.printStackTrace();
		}
		if(fileName.equals("0")){
			file = new File(p.getProperty("0"),p.getProperty("f0"));
		}
		if (fileName.equals("1")) {
				file = new File(p.getProperty("1"),path);
		} else if(fileName.equals("2")) {
			file = new File(p.getProperty("2"),p.getProperty("f2"));
		}else if(fileName.equals("3")){
			file = new File(p.getProperty("3"),p.getProperty("f3"));
		}
		DataHandler	dh= new DataHandler(new FileDataSource(file));
		return dh;
	}
}

测试客户端：

public class MyTest {

	public static void main(String[] args) {

		Service serviceModle = new ObjectServiceFactory().create(MyFile.class,"FileService","http://service.file.org/FileService",null);
		MyFile service = null;
		try {
			service = (MyFile) new XFireProxyFactory().create(serviceModle,"http://192.168.3.67:8080/MyFile/services/FileService");
			Client client = Client.getInstance(service);
			client.setProperty("mtom-enabled","true");
			client.setProperty(HttpTransport.CHUNKING_ENABLED,"true");
		} catch (MalformedURLException e) {
			e.printStackTrace();
		}
		String fileName="3";
		System.out.println("开始传输");
		File file1 = new File("F://","1dsa.txt");
		DataHandler dhl = service.downFile(fileName,null);
		try {
			InputStream in = dhl.getInputStream();
			FileOutputStream out = new FileOutputStream(file1);
			file1.createNewFile();
			byte[] buff = new byte[1024 * 1024];
			int len = -1;
			while (-1 != (len = in.read(buff,buff.length))) {
				out.write(buff,len);
			}
			in.close();
			out.flush();
			out.close();
			System.out.println("传输完毕");
		} catch (IOException e) {
			e.printStackTrace();
		}

	}

}

如果运行客户端报错; javax.xml.stream.FactoryConfigurationError: Provider com.bea.xml.stream.MXParserFactory not found和Exception in thread "main" org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: Fault: java.lang.NullPointerException
org.codehaus.xfire.fault.XFireFault: Fault: java.lang.NullPointerException

看过论坛上有很多帖子对于这个错误都没有解决办法，那我在这里悄悄的告诉你，少包了。少下面这2个包（红框圈住的） 导入这2个包就OK了
