This will enable to choose any file form file system and upload to server. I have used Servlet for handling File upload request for simplicity.
Next thing is that form method should be HTTP POST with enctype as multipart/form-data, which makes file data available in parts inside request body. By the way from Servlet 3.0 API, Servlet is supporting multipart form data and you can use get Part() method of Http Servlet Request to handle file upload.
JSP is similar to PHP and ASP, but it uses the Java programming language.
To deploy and run Java Server Pages, a compatible web server with a servlet container, such as Apache Tomcat or Jetty, is required.
And remember to create a Java package for the project, here we use the package name As you can see, this class has 4 fields according to 4 columns in the table book in database: id, title, author and price. On running, this page looks something like this: As you can see, on this page we have two hyperlinks at the top menu for creating a new book (Add New Book) and showing all books (List All Books). Http Servlet Response; /** * Controller * This servlet acts as a page controller for the application, handling all * requests from the user.
Name the project as Bookstore: Remember to choose Target runtime as Apache Tomcat v8.0 and Dynamic web module version as 3.1 (this is the Java servlet version). Then convert this project to a Maven project by right click on the project, select Configure As you can see, the dependencies here are for Servlet, JSP, JSTL and My SQL connector Java (a JDBC driver for My SQL). The following is code of the object will be passed from a servlet which we will create later.Now, the most difficult but interesting part is implement a Java Servlet that acts as a page controller to handle all requests from the client. Follow this tutorial in case you don’t know how to add Apache Tomcat server in Eclipse.Please note that Tomcat's default port is 8080, but the version refer to in the Downloads section (the pre-configured version), has its port set to 80.Here’s the full source code of the package net.codejava.javaee.bookstore; import tag to determine whether this object is available or not. The JDBC connection information will be read from Servlet’s context parameters. List; /** * Abstract * This DAO class provides CRUD database operations for the table book * in the database.If available (not null) the form is in editing mode, otherwise it is in creating mode. This method is invoked only one time during life cycle of the servlet so it’s reasonable to put the DAO instantiation code here: It looks something like this when an error occurs: So far we have completed the code of the project.
