I'm doing a sales system but on the Sales screen when I give it the option to save I get an error and it does not save me. I'm new to this, the error you come up with is: Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: For input string: ""

If you append the code would be better but as it seems is that you try to convert a String to an int but this has bad format, that is, with Integer.parseInt you have to convert are strings that contain only numbers.

Is there a better way to filter results with PHP / MYSQL? Return Object C # by AJAX (Json - ASP.NET - MVC 5)
