Go to "File" > "New" > "Dynamic Web Project". Enter a project name and click "Next". Choose a Target Runtime (e.g., Apache Tomcat) and click "Next". Configure the project settings as desired and click "Finish". 2. Create a Servlet: Right - click on the src folder in your Dynamic Web Project. Go to "New" > "Servlet". Enter a package name (or use the default) and specify a name for your servlet. Click "Next". Configure the servlet settings (such as URL mapping) and click "Next". Optionally, you can select the checkboxes to generate doGet() and/or doPost() methods if you want to handle GET or POST requests. Click "Finish".
