'Http status 405 - http method get is not supported by this url(Blank Page)
I have a web app that is used as a web online shop. Here customers can log in and search through products and order them.
Admins can review all orders and add/delete products on the app. I have a problem with adding a new product. When I fill out the form on the admin-add-product.jsp page and submit the data, I get redirected to AddProducts servlet, but I only get a blank page and the product isn't added to the database.
admin-add-products.jsp
