Red Hat JBoss Enterprise Application Platform Administration I

The web engine in Red Hat JBoss Enterprise Application Platform 7 (JBoss EAP 7) is Undertow, and it uses the XNIO API.

Undertow provides new features such as load balancing, reduction of number of ports, and support of web sockets and the HTTP/2 protocol.

The five main components in Undertow are: buffer caches, server, servlet container, handlers, and filters.

You can define the default application by changing the welcome-content file handler, or by changing the default-web-module attribute.

You can configure a server with HTTP, HTTPS, and AJP listeners.

To enable an SSL connection, you need a certificate file to identify the servers. The certificate must exist in a Java Key Store (JKS).

JBoss EAP generates a self-signed certificate to enable a default HTTPS port for serving the applications.
