Websocket

One of the most attractive features is JSF 2.3 added native websocket support, it means you can write real-time applications with JSF and no need extra effort.

To enable websocket support, you have to add javax.faces.ENABLE_WEBSOCKET_ENDPOINT in web.xml.

Copy

<context-param>
  <param-name>javax.faces.ENABLE_WEBSOCKET_ENDPOINT</param-name>
  <param-value>true</param-value>
</context-param>

Hello Websocket

Let’s start with a simple example.

* How to use PostgreSQL with WildFly and JBoss

How to connect WildFly to PostgreSQL

Download the PostgreSQL driver

Download a compatible drive with your instance (e.g. PostgreSQL JDBC 4.2 Driver, 42.7.1):

https://jdbc.postgresql.org/download.html

Add PostgreSQL driver to WildFly

In [WILDFLY_HOME]/modules

create the directory:

Copy

`1`	`/org/postgresql/main`

and copy the jdbc file.

Some developers suggest creating the structure in *modules/system/layers/*base adding the custom module to the WildFly/JBoss exiting layered modules. This approach is not recommended by RedHat, here you can read an explanation.
