Struts 1X: Cómo subir un archivo ("uploading")?

Dejo como referencia este código para poder crear un formulario en cual podamos subir (aka "upload") un archivo con Struts 1X.

Código JSP:

<html:form action="/snapshotUploadAction.do" method="post" enctype="multipart/form-data">
File : <html:file property="formFile" /> <html:submit />
</html:form>

<c:if test="${not empty fileUploadForm.message}">
<p style="color:red;">${fileUploadForm.message}</p>
</c:if>

Código del ActionForm:

import org.apache.struts.action.ActionForm;
import org.apache.struts.upload.FormFile;

public class FileUploadForm extends ActionForm {

   private static final long serialVersionUID = 1L;

   protected FormFile formFile;
   protected String message;

   public String getMessage() {
      return message;
   }

   public void setMessage(String message) {
      this.message = message;
   }

   public FormFile getFormFile() {
      return formFile;
   }

   public void setFormFile(FormFile formFile) {
      this.formFile = formFile;
   }
}

Código del Action:

import java.io.File;
import java.io.FileOutputStream;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.upload.FormFile;
import com.eol.core.controller.form.FileUploadForm;

/**
* Basic action to be used to upload files.
* @author gsolano
*
*/
public class FileUploadAction extends Action{

@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
  HttpServletRequest request, HttpServletResponse response)
  throws Exception {

 FileUploadForm uploadForm = (FileUploadForm) form;
 FileOutputStream outputStream = null;
 FormFile formFile = null;
 String path="";
 formFile = uploadForm.getFormFile();

 if(formFile != null) {  
  try { 
     path = getRepositoryPath() +  formFile.getFileName();
     System.out.println("File will be uploaded to this path: " + path);
     outputStream = new FileOutputStream(new File(path));
     outputStream.write(formFile.getFileData());
 
  } catch(Exception exception) {
   System.out.println(exception);
  }
  finally {
      if (outputStream != null) {
          outputStream.close();
      }
  }
  /* Do something with the just uploaded file*/
  processUploadedFile(path);  
  uploadForm.setMessage("The file " + formFile.getFileName() + " was uploaded successfully.");
 }
 return mapping.findForward("success");
}

/**
 *
 * @param path
 */
protected void processUploadedFile(String path) {
 /*MUST OVERRIDE TO DO SOMETHING WITH THE UPLOADED FILE*/
}

/**
 * This path where the file will be uploaded is put in a method to allow
 * classes extending to be able to override it.
 * @return
 */
protected String getRepositoryPath() {
 return getServlet().getServletContext().getRealPath("")+"/";
}
}
