that can be used to interactively execute any standard SQL statement against a database that's running on a server.
This tutorial also assumes that an appropriate servlet/JSP container and database server are available on the server that you're using.
If the ender user linked to /book, it would not take them back to the listing but back to a form, which not correct. We have created the following files for this bookstore example: $ find . ./Web Content/WEB-INF/pages/Book Form ./Web Content/WEB-INF/pages/Book Listing ./src/META-INF/Needed for Java EE dependency injection (CDI) ./src/com/bookstore/Domain/model object ./src/com/bookstore/Book Repository Repository implementation using Java collections (just for testing) ./src/com/bookstore/Book Interface to Book Repository so we can swap it out with JDBC, JPA, JCache and Mongo DB version later ./src/com/bookstore/web/Book Editor Servlet that loads Book (do Get) form and handles Book form submissions (do Post).
This is why we do a send Redirect instead of a forward. It is everything you could want from a CRUD listing. ./src/com/bookstore/web/Book List Servlet that looks up a list of books and displays the listing package com.bookstore; import
Next, create the jsp to list all the users in the Web Content folder.
In this case, it will redirect the request to our servlet to list all the users in the database.
To render the HTML form, the servlet delegates to as follows: (ending in slash) represents a collection of books, while /book (no slash) represents a single book (using REST style URL).
