New features in WildFly
The eighth release of WildFly is based on modular architecture introduced in the previous
release named JBoss AS 7. It has improved on several key points, including areas of per-
formance and management. The most important change for the developers is that this re-
lease implements the Java EE 7 standard completely. Some of the most notable improve-
ments include the following:
• WildFly 8 implements all standards presented by Java EE 7 specifications, which
are also described in this chapter.
• The web server module was completely rewritten under the name Undertow. It
supports both blocking and non-blocking operations. Early performance tests (for
r6&hw=i7&test=plaintext
)
show major performance improvements in HTTP re-
quest handling. Undertow is also available as a separate project and is possible to
be used without WildFly.
• The final WildFly release has reduced the number of used ports. Now, it uses only
two of them, one (
9990
) for management, JMX, and web administration, and the
second one (
8080
) for standard services, including HTTP, WebSockets, remote
JNDI, and EJB invocations.
• Now, it is possible to limit a user's management permissions using the Manage-
ment
role based access control
(
RBAC
). All configuration changes can be
tracked using the audit log.
• For previous releases, any upgrade operation requires a completely new server in-
stallation. WildFly brings the patching feature, allowing to install and rollback
modules using management protocols.
In the next section, we will describe all the required steps to install and start a new applica-
tion server.
