How to Configure Apache Tomcat Server 9 for Your Web Applications
Configuring Apache Tomcat Server 9 for your web applications is an important step in the development process. In this section, we will discuss some of the key configuration options that you can use to customize Tomcat for your specific needs.
Step 1: Configure the Server
The first step in configuring Tomcat for your web applications is to configure the server. This includes settings such as the server port, the shutdown port, and the location of the server logs. You can configure the server by editing the server.xml file in the CATALINA_HOME/conf directory.

<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
Step 2: Configure the Web Applications
The next step is to configure your web applications. This includes settings such as the context path, the servlet mappings, and the security constraints. You can configure your web applications by editing the web.xml file in the WEB-INF directory of your web application.
Here is an example of how to configure a simple servlet mapping:
<servlet>
<servlet-name>HelloServlet</servlet-name>
<servlet-class>com.example.HelloServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloServlet</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>
Step 3: Deploy Your Web Applications
The final step is to deploy your web applications to the Apache Tomcat Server 9. You can do this by copying your web application directory to the CATALINA_HOME/webapps directory. Tomcat will automatically deploy your web application and make it available at the context path that you configured in the web.xml file.
