This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
First, the Felicitos for your excellent blog, right now I'm starting to navigate the worlds of java, jsp and struts the most frequently consulted. I have the sigueinte dilemma: I have a page in struts to upload a file according to date, where when you click the accept button, leads me to my main proceedings (leer.java) and validates that by this date there is no records in the BD to insert them, however if there is need to show a popup window to confirm or user to remove them. As I can create struts a confirmation message that shows the user yes / no and if you choose to send it back to the page leer.java to delete the record in the database and load the new file uploaded.
