Apache Tomcat server is for Java Servlet and JSP. When you call a page that doesn’t exist in the tomcat server, or when an existing page returns an error, the tomcat server will display the version number as shown below. This might be a security risk, especially if you are running an old Tomcat server that has some known exploits.
