Apache Tomcat
Apache Tomcat is a common and frequently used open source Java servlet
container that implements Oracle’s Java Servlet and JavaServer Pages (JSP)
specifications. By doing so, Tomcat provides the means to run Java code in a
web server environment. Java programmers love it because they can write
web applications in a language they already know. Tomcat can be used as a
standalone pure-Java web server, but it is often used in conjunction with the
regular Apache web server or another general-purpose web server. In those
instances, Tomcat serves requests from the other web server.
WildFly
WildFly is more than a web server. It is an application runtime for Java web
applications. As such, it does more than Tomcat, which may be exactly what
you need, or it may be overkill, depending on your project. It is used to host
many enterprise-focused applications and is the open source community-
developed upstream from which Red Hat builds its JBoss Enterprise
Application Platform (EAP).
