import java.io.File;
import java.io.FileOutputStream;

import javax.activation.DataHandler;
import javax.jws.WebService;

@WebService(endpointInterface = "com.ws.mtom.WSInterface")
public class WSImpl implements WSInterface {

    @Override
    public String writeFile(DataHandler sTr) {
        try {
            File file = new File("D:\\xml\\efg.xml");
            file.createNewFile();
            FileOutputStream fop = new FileOutputStream(file);    
            sTr.writeTo(fop);           
        } catch (Exception e) {
            return "Fail to write content in file";
        }
        return "Chutiyap hogaya hai.";

        Service service = Service.create(wsdlUrl, qname);
        DataSource ds = new ByteArrayDataSource(getFileContentAsString("D:\\xml\\abc.xml").getBytes(), "text/plain; charset=UTF-8");
        DataHandler handler = new DataHandler(ds);

Try this :

   FileWriter fw = new FileWriter(file.getAbsoluteFile());
    BufferedWriter bw = new BufferedWriter(fw);
    //convert your DataHandler to String
    String stringToWrite = IOUtils.toString(sTr.getInputStream, "UTF-8");
    //Write String to file
    bw.write(stringToWrite);
