WebApplicationContextFacesELResolver

extends ELResolver
java.lang.Object
   ↳ ELResolver
     ↳ org.springframework.web.jsf.el.WebApplicationContextFacesELResolver

Class Overview

Special JSF 1.2 ELResolver that exposes the Spring WebApplicationContext instance under a variable named "webApplicationContext".

In contrast to SpringBeanFacesELResolver, this ELResolver variant does not resolve JSF variable names as Spring bean names. It rather exposes Spring's root WebApplicationContext itself under a special name, and is able to resolve "webApplicationContext.mySpringManagedBusinessObject" dereferences to Spring-defined beans in that application context.

Configure this resolver in your faces-config.xml file as follows: 

 <application>
   ...
   <el-resolver>org.springframework.web.jsf.el.WebApplicationContextFacesELResolver</el-resolver>
 </application>
