Please use NetBeans IDE with Tomcat Server to edit the attached Java web project called Product_Maintenance. The attached PDF describes all the functionality this web application should have. All JSP’s should look similar to the screenshots in this document. Listed below are the details for this project.
Operation
When the application starts, it displays the Index page. This page contains a link that leads to the Products page that can be used to add, update, or delete products.
To add a new product, the user selects the Add Product button. This displays the Product page with all text fields empty. Then, the user can fill in the text fields and click on the Update Product button to add the product.
To edit an existing product, the user selects the Edit link for the product. This displays the Product page with all existing data for the product displayed. Then, the user can edit any entries and click on the Update Product button to update the data for the existing product.
To delete a product, the user selects the Delete link for the product. This displays the Confirm Delete page. Then, if the user confirms the deletion by selecting the Yes button, the product is deleted and the Products page is displayed to reflect the new data. If the user selects the No button, the Products page is displayed.
Specifications
Use a Product class like the one shown later in this document to store the product data.
Use a ProductIO class like the one shown later in this document to read and write the product data to a text file named products.txt in the WEB-INF directory.
Use a text file like the products.txt file shown later in this document as a starting point for the products that are available to the application.
Use server-side validation to validate all user entries. In particular, make sure the user enters a code, description, and price for each product. In addition, make sure the product’s price is a valid double value.
The Product.java, ProductIO.java, and product.txt files are attached in the “midterm_project” zipped folder in Blackboard.
