How to configure and deploy a web application in Tomcat?

To configure and deploy a web application in Tomcat, you can follow these steps:

1. Create a new directory in the webapps folder of Tomcat to store files for the web application.
2. Copy all files of the web application (such as HTML, JSP, Servlet, static resources, etc.) to this newly created directory.
3. Find the server.xml file in the conf directory of Tomcat, modify it by adding a new tag within the existing tag to specify the path and corresponding directory for the Web application, for example:

<Context path="/mywebapp" docBase="/path/to/mywebapp" />

The path property in Tomcat defines the access path of the web application, while the docBase property specifies the directory path where the web application is located.

1. Save the server.xml file and restart the Tomcat server.
2. Visit http://localhost:8080/mywebapp (assuming the port number is 8080) to access the deployed web application.

It is important to ensure the correct file structure of a web application, including the WEB-INF directory and web.xml configuration file when deploying a web application. Additionally, Tomcat Manager can be used for deploying and managing web applications.
