How to deploy a war file in Tomcat 7

To deploy a WAR (Web ARchive) file in Apache Tomcat 7, you can follow these steps:

  1. Place the WAR file in the webapps directory of your Tomcat installation. The default location is /usr/local/tomcat/webapps on Linux and C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps on Windows.

  2. Start the Tomcat server if it is not already running.

  3. Open a web browser and navigate to http://localhost:8080/, where 8080 is the default port number for Tomcat.

  4. The WAR file will be automatically deployed and a new folder with the same name as the WAR file will be created in the webapps directory. The contents of the WAR file will be extracted to this folder.

  5. You can access the web application by appending the context path of the application to the base URL. The context path is the name of the WAR file without the .war extension. For example, if the WAR file is named myapp.war, the context path is /myapp and you can access the application at http://localhost:8080/myapp/.

Note: These steps assume that you have already installed Tomcat and set it up correctly. If you have not done so, you can follow the instructions in the Tomcat documentation to install and configure Tomcat.
