java.lang.Objectjavax.el.ELResolver
org.springframework.web.jsf.el.WebApplicationContextFacesELResolver
public class WebApplicationContextFacesELResolver
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>
