struts upload with DynaValidatorForm

[Niklas Rosencrantz]

IS something like the following good practice for file upload with struts?
Does it work with struts 1.3.9?

  <form-bean name="uploadItemForm" type="org.apache.struts.validator.DynaValidatorForm">
 <form-property name="newItem"
  type="org.apache.struts.upload.FormFile" />
</form-bean>
 

package p;
/**
 *
 * @author developer
 * CreateAction.java
 *
 */
import org.apache.struts.action.*;
import org.apache.struts.upload.*;
import java.sql.*;
import javax.servlet.http.*;
import java.io.*;
import javax.imageio.*;
public class CreateAction extends Action {
    public ActionForward execute(
            ActionMapping mapping,
            ActionForm form,
            HttpServletRequest request,
            HttpServletResponse response) throws Exception {      
        DynaValidatorForm dForm = (DynaValidatorForm) form;     
        FormFile file= (FormFile) dForm.get("file");
        FileOutputStream fileOut = new FileOutputStream(file.getFileName());
        byte[] data= file.getFileData();
        fileOut.write(data);
        fileOut.flush();
        fileOut.close();       
        return mapping.findForward("success");
    }
}  

Thank you
