Problems converting access database to excel

Question

is there any method to convert access db to excel spreadsheet.
currently i'm using a 'cheat' way of retrieving the results to a table and convert to excel using this:
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition","attachment; filename=\"file.xls\";");
the problem is that i need to delete the records in the database after saving the the excel file. this method does not let me perform response.sendRedirect() method after saving as excel. so, after i retrieve the results into a table, i delete the records in the database and prompt the user to save the excel file. this is risky cos if the user select cancel when prompted to save, the records in the databse will long be gone.
i need help if anyone could suggest a solution to this.
1. another method to convert access db to excel spreadsheet , or
2. the excel file will be saved automatically without having the user to click to save, or
3. to be able to get to delete the db records after saving.
i really need the help from you people. thanks.

Answer 1

I find your problem description confusing.
Here's what it sounds like you're saying:
You've got records in an Access database to start with. A user makes a request to see records in a browser. You've got a servlet that queries the Access database using JDBC, turns the result set into a CSV file, sets the content type to "application/vnd.ms-excel", and then displays the response as an MS Excel spreadsheet in the browser.
So far, so good?
That sounds like one use case to me - call it "Query Database For Records".
Then it sounds like you want to implement another use case - call it "Modify Database". You'd like to be able to let the client manipulate the Excel data you've sent down and then resynch with the database when they say they're done.
Again, okay?
If that's true, treat them like two separate cases. It sounds like you want to do a multipart file upload of the Excel data where you'd have your servlet take the uploaded data and insert it back into the Access database.
If I understand you correctly, Access is your persistence mechanism. I don't understand why you'd want to update Access AND save the Excel file. I read this as "I want to have one data source of record with the latest info, and I happen to like sending it down to clients in an Excel spreadsheet because that's what they're used to seeing."
I'm sure this doesn't help you solve your problem yet, but it might help my understanding of what you're really trying to do here. - MOD
