T5 Deletion of the uploaded file?

[ael <al...@dash.com.ph>]

Any guide on how to delete the uploaded file?

Any best practice?

Or I will just use the java io?

//////////////// Java Delete using io ////////////////

    String fileName = "file.txt";
    // A File object to represent the filename
    File f = new File(fileName);

    // Make sure the file or directory exists and isn't write protected
    if (!f.exists())
      throw new IllegalArgumentException(
          "Delete: no such file or directory: " + fileName);

    if (!f.canWrite())
      throw new IllegalArgumentException("Delete: write protected: "
          + fileName);

    // If it is a directory, make sure it is empty
    if (f.isDirectory()) {
      String[] files = f.list();
      if (files.length > 0)
        throw new IllegalArgumentException(
            "Delete: directory not empty: " + fileName);
    }

    // Attempt to delete it
    boolean success = f.delete();

    if (!success)
      throw new IllegalArgumentException("Delete: deletion failed");


////////////// Upload File //////////////////

Java Class

public class Index
{
	@Property
        private UploadedFile file;

        public void onSuccess()
        {
            File copied = new File("C:/temp/" + file.getFileName());
            
            file.write(copied);
        }
        
        @Persist(PersistenceConstants.FLASH)
        @Property
        private String message;


        Object onUploadException(FileUploadException ex)
        {
            message = "Upload exception: " + ex.getMessage();

            return this;
        }
}
