Can I use multiple EL resolvers in JSF 2.0?

I would like to know about EL-resolvers in JSF. Can we use several EL resolvers in a project ?. Say, if I use Spring DelegatingVariableResolver , can I add another EL resolver like Seam SeamELResolver ?

My expectation is DelegatingVariableResolver delegate to another EL recognizer when it receives an error or exception during the translation process.

DelegatingVariableResolver is deprecated since Spring 3.2, then yes, you can declare several ElResolver as:

 <application> <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver> <el-resolver>com.agitech.erp.bean.BeanResolver</el-resolver> <locale-config> <default-locale>fr</default-locale> </locale-config> </application> public class BeanResolver extends javax.el.ELResolver { ........ }

if you use MyFaces, you can choose a way to organize custom transformers using

 <context-param> <param-name>org.apache.myfaces.EL_RESOLVER_COMPARATOR</param-name> <param-value>org.apache.myfaces.el.unified.CustomLastELResolverComparator</param-value> </context-param>
