  • Configure Tomcat's server.xml file to set ports, deployment paths, etc.

2. Create a Java Web Application

  • Create a new Java Web application that contains Servlets, JSPs, and other files.
  • Make sure your application complies with the Java EE specification.

3. Package the application as a WAR file

  • Use a build tool such as Maven or Gradle to package the application as a WAR (Web archive) document.

4. Deploy the WAR file to Tomcat

  • Copy the WAR file to Tomcat’s webapps directory.
  • Tomcat will automatically unpack the WAR file and deploy it as a web application.

5. Start Tomcat

  • Start the Tomcat server. You can run catalina.sh start from the command line or startup.bat in Windows.

6. Access the Web application

  • Open the URL of the Tomcat server in the browser (for example, http://localhost: 8080/your-application-name).
  • This will load and execute your Java web application.

Tips:

  • The default port of Tomcat is 8080.
  • You can configure the deployment settings of your web application in Tomcat's conf/web.xml file.
