Hi Guys,


What i'm trying to achieve:


I'm creating a B2 that the user will upload a .csv and the B2 will add the file data to a custom table. It works fine when the user upload a csv file with 15k rows and 4 columns (961kb), but when i double that  the upload page redirect the user to a "file not found" page.


The csv that i need to upload have more then 1kk rows with 20 columns (10 int, 10 varchars). I'm using:



DiskFileItemFactory factory = new DiskFileItemFactory();

ServletFileUpload upload = new ServletFileUpload(factory);

List<FileItem> fields = upload.parseRequest(request);

Iterator<FileItem> it = fields.iterator();


and returning a string List of the fileItem.getString() it found. With the result, i tried two ways:


Creating a unique sql query string
Did each insert separately


Both ways are not working for larger files. In this case, what would be the best approach to insert multiple values?
