Getting RichFaces version in runtime

Did you ever need to know or display RichFaces version or revision when running your application? It’s rather easy to do. RichFaces registers VersionBean bean under a4j name which can give you that information.

<h:panelGrid columns="2">
   <h:outputText value="Project name:" />
   <h:outputText value="#{a4j.projectName}" />
   <h:outputText value="Vendor:" />
   <h:outputText value="#{a4j.vendor}" />
   <h:outputText value="Version:" />
   <h:outputText value="#{a4j.version}" />
</h:panelGrid>

Output:

Project name: 	Jboss Richfaces
Vendor: 	richfaces.org
Version: 	v.3.3.1.GA SVN $Revision: 14228 $ $Date: 2009-05-14 09:56:51 -0700 (Thu, 14 May 2009) $

You can also just render #{a4j}, then you will get:

Jboss Richfaces by richfaces.org, version v.3.3.1.GA SVN $Revision: 14228 $ $Date: 2009-05-14 09:56:51
