Class WebApplicationContextFacesELResolver
java.lang.Object
javax.el.ELResolver
org.springframework.web.jsf.el.WebApplicationContextFacesELResolver
public class WebApplicationContextFacesELResolver
- extends javax.el.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>
