Apache | Integrating with Tomcat (mod_proxy_ajp) | Creating a Simple Web App in Tomcat

Tags:

First, configure Tomcat so it works by itself. The goal is to run a simple JSP through Apache that displays only Tomcat Page from Tomcat.

For the web program created here, create a directory named hello under {Tomcat installation directory}/webapps.

C:\apache\apache-tomcat-9.0.29\webapps>dir

C:\apache\apache-tomcat-9.0.29\webapps>

In the created directory, create the configuration file {Tomcat installation directory}/webapps/hello/WEB-INF/web.xml and write the following.

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0">

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

</web-app>

Then create the file {Tomcat installation directory}/webapps/hello/index.jsp, which will be displayed on the screen, and write the following.

<html>
<body>
<h1>Tomcat Page</h1>
</body>
</html>

Now run the command file {Tomcat installation directory}/bin/startup.bat to start Tomcat. A console window like the following should appear.
