## org.springframework.web.jsf.el
Class WebApplicationContextFacesELResolver

    java.lang.Object
      javax.el.ELResolver
          org.springframework.web.jsf.el.WebApplicationContextFacesELResolver

    public class WebApplicationContextFacesELResolver

extends ELResolver

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>
