Posted ByJava Servlets are basically objects which sends back a response based on the incoming request. They are basically used to extend the functionality of a web server. To implement a servlet, you need to have the servlet-api.jar and since we’re using MySQL for DB authentication, you also need to have the mysql-connector-java-bin.jar. Without these two, your application won’t run.If you’re using Netbeans and have GlassFish Server installed, the servlet-api.jar will already be there in your library. If no, you can manually add it. For MySQL connectivity, you will need to manually add the JAR. If you’re using Eclipse, to create a Servlet project, you need to have the Java Web plugin and Apache Tomcat (or any other server for the matter) installed. If you’re not aware of how to check the MySQL connectivity from NetBeans, you can check out this.

How To Create A Servlet Project In NetbeansThe first thing that you need to do to create a servlet project on Netbeans is choose Java Web from the categories. After that, select Web Application. Once you have done this, your JARs will get added to the Libraries.Tech Tip: Need to catch up your coding work urgently? Get an instant access to your online private work space on your preferred device(PC/Mac/android/iOS) to build/test web projects online with remotely accessible virtual PCs from, You can also access complete MS office on the same work space by visiting. Try out hosted SharePoint and Exchange from Apps4Rent to enhance your team collaboration. Building the ApplicationNow that you’re all set, you can get into the coding part.

The first thing that you need to do is modify the servlet file. You will need to get the data from your HTML file and authenticate it against the MySQL database. For utilising MySQL, I have installed. You can just run it and then connect to the DB. Always make sure the server is running, before trying to run the project.Here’s the servlet code that I have used.
